Java while

What is Loops?

When we want to execute a block execute multiple time then we use loop.It executes until condition is true.

The while executes a block of code as long as a given condition is true.

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

Sample program with if
Write a program or WAP to print 1 to 10 using while loop.

class SampleSwitch
{
   public static void main(String args[])
   {
        int num= 4;
	while (num <= 10) {
	  System.out.println(num);
	  num++;
	}
   }
}

Output:

1
2
3
4
5
6
7
8
9
10
