Java calss and Method & Constructor Invocation and Variable Hiding pro

    Java Class Program

package com.jbt;

import java.lang.*;

public class testclass

{

public int i;

static

{

System.out.println("This is static block");

}

 {

System.out.println("This is ananuymous block");

}

testclass()

{

System.out.println("This is constructor");

}

void methid()

{

System.out.println("This is method");

}

}

class anotherclass

{

}

Syntax of Constructor

public class Constructor

{

public Constructor ()

{

System.out.println("Inside Constructor");

}

static void method()

{

System.out.println("This is in method");

  }

}

Constructor Invocation

public class ConstructorExample

{

public ConstructorExample()

{

System.out.println("Inside Constructor");

}

public static void main(String args[])

{

ConstructorExample cls = new ConstructorExample();

   }

}

Method Invocation

public class ConstructorExample

{

public ConstructorExample()

{

System.out.println("Inside Constructor");

}

void method()

{

System.out.println("This is in method");

}

public static void main(String args[])

          {

ConstructorExample cls = new ConstructorExample();

cls.method();

}

}

Variable Hiding

class Jbt

{

int variable = 5;

public static void main(String args[])

{

Jbt obj = new Jbt();

obj.method(20);

obj.method();

}

void method(int variable)

{

variable = 10;

System.out.println("Value of variable :" + variable);

}

void method()

{

int variable = 40;

System.out.println("Value of variable :" + variable);

}

}
