Example:

In the example below, the if code block is created which executes only when the variable called i is divisible by 3.

public class MyClass {
  public static void main(String[] args) {
    int i = 15;
    if (i % 3 == 0)
      System.out.println(i+" is divisible by 3.");
  }
}

The output of the above code will be:
