println whitespace

[mickey0]

Hello,
is there any chance to do it in a fashion way?

for (int i=5; i >= 0; i--) {
  System.out.prinln( space*i + "Hello world!");
}

I want get this:

     Hello world!
   Hello world!
  Hello world!
 Hello world!
Hello world!

thanks

for (int i=5; i>=0; i--) {
  for (int j=i; j>=1; j--) {
    System.out.print(" ");
  }
  System.out.println( "Hello world!"); /* NOTICE you misspelled print */
}

sorry, I was lloking for something general to do this and hopefully work around with the "printf"; in fact what about if I needed the opposite?

Hello!
 Hello!
  Hello!
   Hello!

Thanks

To increase spaces:

    public static void example(Integer num) {
        for (int i = num; i >= 0; i--) {
            for (int j = i; j < num; j++) {
                System.out.print(" ");
            }
            System.out.println("Hello world!");
        }
    }

    public static void main(String[] args) {
        example(5);
    }

To reduce spaces:

    public static void example(Integer num) {
        for (int i = num; i >= 0; i--) {
            for (int j = i; j > 0; j--) {
                System.out.print(" ");
            }
            System.out.println("Hello world!");
        }
    }

    public static void main(String[] args) {
        example(5);
    }

Probably be able to make that a lot more efficient, but you get the idea.

A shorter way:

for (int i=5; i>=0; i--) { 
  System.out.println("     ".substring(i) + "Hello world!"); /* NOTICE: 5 spaces */ 
}

That's a great idea chaarmann!

yes, but in that way I can't see I cood get the opposite:

Hello
 Hello
   Hello

for (int i=0; i<=5; i++) {
  System.out.println("     ".substring(i) + "Hello world!");
}
