Do while and Foreach Loop in Java

Do While

package javaapplication7;

public class JavaApplication7 {

   

    public static void main(String[] args)

    {

        int i=10;

        do 

        {

            System.out.println(i);

            i--;

        } while (i>0);

        

       

    }

    

}

Foreach 

package javaapplication8;

public class JavaApplication8 {

    

    public static void main(String[] args) 

    {

        String[] fruits = new String[] { "Orange", "Apple", "Pear", "Strawberry" };

     for (String x : fruits)

     {

         System.out.println(x);

    

     }

    

}

}

While Loop in Java with Factorial Program example

package javaapplication6;





public class JavaApplication6 {



   

    public static void main(String[] args)

    {

      int fac=1;

        int i=25,temp;

        temp=i;

        while(i>=1)

        {

        fac=fac*i;

        i--;   

        }

       

        System.out.println(temp+"!="+fac);

    }

   

}

        System.out.println("Total from addition "+(esum+osum));

       

        System.out.println("Total from loop "+tsum);
