Question

  public class Test {
        public static void main(String[] args){
            if (5.0 > 5) // (5.0<5) for both case it is going to else
                System.out.println("5.0 is greater than 5");
            else 
                System.out.println("else part always comes here");
                     /*another sample*/
            if (5.0 == 5) 
                System.out.println("equals");
            else 
                System.out.println("not equal");
        }
    }

can any one explain the first “if statement” why it always come to else part

second else part prints “equals “

Answer 1

You’re testing whether or not (5.0 < 5) or (5.0 > 5). Since (5.0 == 5) then that means it’s not less then 5 (false) and not greater then 5 (false). So both (5.0 < 5) and (5.0 > 5) will return false and you will always hit the else statement.

If you did the following (which is what you did in the second half):

if (5.0 == 5)
    System.out.println("5.0 is equal to 5");
else 
    System.out.println("else part always comes here");

Then you will no longer hit the else statement (as you saw in the second half of your question).
