Question

I was wondering how would you use the printf in Java to align a string Output to the right?

Assuming I have 2 numbers, represented as a String. eg:

123,321,321,321 
    321,324,213+

How would I align them like that?

Its

System.out.printf( "%s something ", name) ;

I can’t seem to find the % index online

Answer 1

int len = 15;
String spacer = String.format("%" + len + "d", 0).replace("0", " ");

String myNumber1 = "123,321,321,321";
String myNumber2 = "321,324,213";

System.out.println(spacer.substring(myNumber1.length()) + myNumber1);
System.out.println(spacer.substring(myNumber2.length()) + myNumber2);

This is called formatting. You can learn very interesting things here.
