Java using boolean program

Primitive Boolean constants

package com.java2novice.wrapper.booleanexp;

 public class MyBooleanConstants

 {

     public static void main(String a[])

   {

        System.out.println("Boolean object corresponding to the primitive value false"+Boolean.false);

        System.out.println("Boolean object corresponding to the primitive value true"

        +Boolean.true);

    }

}

Convert string to Boolean value

package com.java2novice.wrapper.booleanexp;

public class MyStringToBoolean

{

    public static void main(String a[])

    {

        String strBol = "true";

        Boolean bol = Boolean.parseBoolean(strBol);

        System.out.println(bol);

    }

}

Create Boolean wrapper object

package com.java2novice.wrapper.booleanexp;

public class MyBasicBoolean

{

     public static void main(String a[])

    {

        boolean b1 = true;

        Boolean bObj1 = new Boolean(b1);

        System.out.println("Wrapper class Boolean output: "+bObj1);

        Boolean bObj2 = new Boolean("false");

        System.out.println("Wrapper class Boolean output: "+bObj2);

        System.out.println(bObj1.booleanValue());

    }

}

Write byte content to a file in java Program

package com.java2novice.files;

import java.io.File;

import java.io.FileOutputStream;

import java.io.IOException;

import java.io.OutputStream;

public class ByteWriteToFile

{

    public static void main(String[] args)

    {   

        OutputStream opStream = null;

        try

        {

            String strContent = "This example shows how to write byte content to a file";

            byte[] byteContent = strContent.getBytes();

            File myFile = new File("C:/MyTestFile.txt");

            if (!myFile.exists())

           {

                myFile.createNewFile();

            }

            opStream = new FileOutputStream(myFile);

            opStream.write(byteContent);

            opStream.flush();

            }

           catch (IOException e)

           {

            e.printStackTrace();

           }

             finally

          {

              try

          {

                if(opStream != null) opStream.close();

            }

            catch(Exception ex){}

        }

    }

}
