My issue

i didnt undestand

This is the code

class Codechef {
  public static void main(String[] args) {
    int a = 4;
    int b = 1;
    while (a != b) {
      System.out.print(b + " ");
      b = b + 1;

The loop starts with a = 4 and b = 1.
Initially a is not equal to b because 4 != 1. So the code inside loop will execute and b (which is 1) will be printed. Inside the loop b also gets updated to b+1 that is 2.

Now the loop will continue and b will keep printing until a becomes equal to b. That will happen when b become 4 and the loop will stop. Thus when b becomes 4, nothing will be printed.
