Difference between Comparable and Comparator Interface

Comparable 
1) Comparable is an interface.

2) Comparable is located in the java.lang package

3) It is in the collections framework of java since java 1.2.

4) Its author is Josh Bloch.

5) Comparable interface contains  one methos i.e "int compareTo(Object o)" to implement.

6) It compares this object with the argument object for sorting order. and it returns the
negative integer or zero or positive integer value based on this object is greater than
or equal to the specified argument object.

7) It throws ClassCastException if the specified object prevents it from being compare to this object.

8) Except Number class most of the

Interface

package java.lang;
import java.util.*;
public interface Comparable {
  public int compareTo(T o);
}

Example:

/**
 * @author raj
 *
 */
public class Planet implements Comparable{
private int size;
private String name;

public Planet(String name, int size) {
this.setName(name);
this.setSize(size);
}

public int compareTo(Planet planet) {

return  this.getSize() == planet.getSize() ? 0
  : this.getSize() < planet.getSize() ? -1
  : 1;

}

public String toString() {
StringBuilder builder = new StringBuilder();
builder.append(getName());
builder.append(" : ");
builder.append(getSize());
return builder.toString();
}

public int getSize() {
return size;
}

public void setSize(int size) {
this.size = size;
}

public String getName() {
return name;
}

public void setName(String name) {
this.name = name;
}
}

import java.util.ArrayList;
import java.util.Collections;
import java.util.List;


public class PlanetEngine {
public static void main(String[] args) {
Planet p0 = new Planet("sun",0);
Planet p1 = new Planet("mercury",1);
Planet p2 = new Planet("venus",2);
Planet p3 = new Planet("earth",3);
Planet p4 = new Planet("mars",4);
Planet p5 = new Planet("saturn",5);
Planet p6 = new Planet("jupiter",6);
Planet p7 = new Planet("uranus",7);
Planet p8 = new Planet("neptune",8);
Planet p9 = new Planet("pluto",9);

List list = new ArrayList();
list.add(p0);
list.add(p1);
list.add(p2);
list.add(p3);
list.add(p4);
list.add(p5);
list.add(p6);
list.add(p7);
list.add(p8);
list.add(p9);

System.out.println("\n\nSORGING BYE SIZE USING COMPARABLE ");
Collections.sort(list);

for(Planet p : list) {
System.out.println(p);
}
}
}


In this example the compare to method returns the negative , zero, or positive integer values based on the size of the planet. means based on the planet size the sorting will be done.

Comparator
1) Comparator is an Interface
2) It is resides into the java.util package
3) It is in the java since java 1.2
4) Its author is Josh Bloch and Neal Gafter.
5) Comparator contains two methods 1) int compare(Object o1, Object o2) 2) boolean equals(Object objt).
6) The compare method compares two objects. It compares the first object with
the second object and based on the comparision it returs negative, zero or positive integer value.
7) It throws ClassCastException if the object
8) One can create multiple comparator based on the required sorting types.

Interface code

package java.util;
public interface Comparator {
  int compare(T o1, T o2);
  boolean equals(Object obj);
}

Example
import java.util.Comparator;


public class PlanetComparatorByName implements Comparator{

public int compare(Planet p1, Planet p2) {

if(p1.getName()==null && p2.getName()==null) {
return 0;

} else if(p1.getName()==null && p2.getName()!=null) {
return -1;

} else if(p1.getName()!=null && p2.getName()==null) {
return 1;

} else if(p1.getName().length()>p2.getName().length()) {
return 1;

} else if(p1.getName().length() return -1;

} else {
return p1.compareTo(p2);
}

}

}

import java.util.ArrayList;
import java.util.Collections;
import java.util.List;


public class PlanetEngine {
public static void main(String[] args) {
Planet p0 = new Planet("sun",0);
Planet p1 = new Planet("mercury",1);
Planet p2 = new Planet("venus",2);
Planet p3 = new Planet("earth",3);

Planet p6 = new Planet("jupiter",6);
Planet p7 = new Planet("uranus",7);
Planet p8 = new Planet("neptune",8);
Planet p9 = new Planet("pluto",9);

List list = new ArrayList();
list.add(p0);
list.add(p1);
list.add(p2);
list.add(p3);
list.add(p4);
list.add(p5);
list.add(p6);

System.out.println("\n\nSORGING BYE NAME LENGTH USING COMPARATOR ");
Collections.sort(list, new PlanetComparatorByName());

for(Planet p : list) {

Struts actions redirect and action chaining

Action redirect jsp code:

 <package name="default" extends="struts-default">  
   <action name="user" class="com.raj.UserAction">  
     <result name="success" type="redirect">REDIRECT_ACTION</result>  
   </action>  
   <action name="saveAction" class="com.raj.SaveAction">  
     <result name="success">/success.jsp</result>  
   </action>  
 </package>  

In Action redirect it makes a complete a new call to the new action. so the values in to the stack will be of the new actions. while in the case of the action chaining it will make the call to the new action with the values of the previous action and the values of the new actions. Action Chaining jsp code:

 <package name="default" extends="struts-default">  
   <action name="user" class="com.raj.UserAction">  
     <result name="success" type="chain">CHAIN_ACTION</result>  
   </action>  
   <action name="saveAction" class="com.raj.SaveAction">  
     <result name="success">/success.jsp</result>  
   </action>  
 </package>

for complete detail information about the Filter usage with example.

How to use projection in Hibernate ?

The projections concept is introduced in hibernate
3.0 and mainly we can do the following two operations using the projection
We can load partial object from the database
We can find the Result of Aggregate functions
Projection is an Interface given in “org.hibernate.criterion” package, Projections is a class
given in same package, actually Projection is an interface, and Projections is a class and is a
factory for producing projection objects.
In Projections class, we have all static methods and each method of this class returns
Projection interface object.
If we want to add a Projection object to Criteria then we need to call a
method setProjection()
Remember : while adding projection object to criteria, it is possible to add one object at a
time. It means if we add 2nd projection object then this 2nd one will overrides the first one
(first one wont be work), so at a time we can have only one projection object to criteria
object.
Using criteria, if we want to load partial object from the database, then we need to create a
projection object for property that is to be loaded from the database

How to use?
Criteria criteria = session.createCriteria(Entity.class);
criteria.setProjection(Projections.property("name"));
List list = criteria.list();
Iterator iterator = list.iterator();
while(iterator.hasNext())
{
             String s = (String) iterator.next();
             // ---- further code -----
}

If we add multiple projections to criteria then the last projection added will be considered
to execute

Criteria criteria = session.createCriteria(Entity.class);

Projection p1 = Projection.property("id");
Projection p2 = Projection.property("name");
criteria.setProjection(p1):
criteria.setProjection(p2):
List list=crit.list();

Here collectiions list, is going to contain the name in the form of String objects, but Entity id are
over ridden, second projection over rides the first one, i mean p2 only will works p1 will not works,
actually there is a way to add multiple projections to criteria to select more than one column value.

SessionFactory sessionFactoryObj = configurationObj.buildSessionFactory();
Session sessionObj = sessionFactoryObj.openSession();

Criteria criteriaObj = sessionObj.createCriteria(Entity.class);
criteriaObj.addOrder(Order.desc("id"));

ProjectionList projList = Projections.projectionList();
projList.add(Projections.property("id"));
projList.add(Projections.property("category"));
criteriaObj.setProjection(projList);

List entityList = criteriaObj.list();
Iterator iteratorObj = entityList.iterator();
System.out.println("ID \t CATEGORY ");

while(iteratorObj.hasNext()){
       Object data[] = (Object[])iteratorObj.next();
      System.out.println(data[0]+" \t "+data[1]);
}

How to use criterion in Hibernate ?

Criterion 
Criteria criteria = session.createCriteria(Entity.class);
Criterion criterion =Restrictions.gt("id", new Integer(11));
// .gt() : means greater than
// id is a variable of our POJO class Entity.java
criteria.add(criterion); // adding criterion object to criteria class object
List l = criteria.list(); // executing criteria query

In our above example we are fetching the data by comparing id greater than (>) 11
If we want to put more conditions on the data (multiple conditions) then we can use
.and() method ,. or() method , .eq() method using the Restrictions class

Restrictions
Criteria criteria = session.createCriteria(Entity.class);
criteria.add(Restrictions.and(Restrictions.like("name","%M%"),Restrictions.eq("category",ne
w String(“bird”))));
List list = criteria.list();
Iterator it = list.iterator();

Configuration configurationObj = new Configuration();
configurationObj.configure("hibernate.cfg.xml");

SessionFactory sessionFactoryObj = configurationObj.buildSessionFactory();
Session sessionObj = sessionFactoryObj.openSession();

Criteria criteriaObj = sessionObj.createCriteria(Entity.class);
Criterion criterion = Restrictions.gt("id", new Integer(0)); 
// means : where id > 0

criteriaObj.add(criterion);

criteriaObj.addOrder(Order.desc("id")); 
// will fetch the data into descending order
//criteriaObj.addOrder(Order.asc("id")); 

// will fetch the data into ascending order
List entityList = criteriaObj.list();
Iterator entityListIterator=entityList.iterator();
System.out.println("ID\t NAME \t CATEGORY");
System.out.println("-------------------------");
while(entityListIterator.hasNext()){
            Entity entityObj=(Entity)entityListIterator.next();            System.out.print(entityObj.getId());            System.out.print(" \t"+entityObj.getName());            System.out.println(" \t"+entityObj.getCategory());
}
System.out.println("-------------------------");
sessionObj.close();
sessionFactoryObj.close();

Hibernate + How to add condition in annotation ?

There are two ways to add the condition/where clause into the annotation class
1) at the class level
2) at the field method or field declaration

@Entity
@Table(name = "TBLM_PACKAGE")
@Where(clause = "PACKAGE_MODE!='DESIGN'")
public class PkgData{

       private String packageMode;


      @Column(name = "PACKAGE_MODE")
public String getPackageMode() {
return packageMode;
}

public void setPackageMode(String packageMode) {
this.packageMode = packageMode;
}

}

Everything about java main(String[] args) method

main method is the first method which get called automatically when the program executes.
there  must be only one main in a java program which you want to execute.
in main method signature/prototype 
public : 
It is a access specifier which defines the scope of the method it must be public

static: 
makes the method  to be called with the class name as to run the program we use the class name. thats is the reason static is there in main method.

void:
void states that the main method doesnt return anything. and it must be void only.

main : it is a name of method.

(String[] args) :  here args is an array of String class and it must be string class array only.
here instead of String[] args you can use varargs i.e String... args

main method cannot be override
main method can be overloaded.
