while(true) java code example

Example 1: while loop in java

public class WhileLoopDemo
{
   public static void main(String args[])
   {
      int a = 1;
      while(a < 10)
      {
         System.out.println(a);
         a++;
         System.out.print("\n");
      }
   }
}

Example 2: while loop in java

// Java infinite while loop
import java.util.*;
public class WhileLoopExample
{
   public static void main(String[] args)
   {
      boolean value = true;
      while(value)
      {
         System.out.println("Infinite loop");
      }
   }
}

Example 3: loop while in java

while(i < 5) //while i < 5 stay in the loop
{
  System.out.print(i);
  i++;
}
/*
	do someting
	change variable
    call methods
    etc...
*/

Example 4: java while

while (condition) {
  // code block to be executed
}

Example 5: while loop in java

// Iterate Array using while loop
public class ArrayWhileLoop
{
   public static void main(String[] args) 
   {
      int[] arrNumbers = {2, 4, 6, 8, 10, 12};
      int a = 0;
      System.out.println("Printing even numbers: ");
      while(a < 6)
      {
         System.out.println(arrNumbers[a]);
         a++;
      }
   }
}
