The while loop is used to iterate the part of the program several times and if the iteration is not fixed then you can use while loop.
class Counting
{
public static void main(String args[])
{
int i=1;
while(i<=10)
{
System.out.println(i);
i++;
}
}
}
Output:
1
2
3
4
5
6
7
8
9
10
If you pass true in the while loop then it will be the infinitive loop(endless loop).
class InfiniteLoop
{
public static void main(String args[])
{
while(true)
{
System.out.println("Infinite loop");
}
}
}
Output:
Infinite loop
Infinite loop
Infinite loop
