Printf in Java with variable spaces [duplicate]

Question

I have a problem with printf in java. I would like to define the spaces with a variable.

    String a = "bar";
    String b ="foo";

     System.out.printf("%-10s %s", b, a);

//Output:foo*7spaces*bar

The "10" should be changeable. I hope you know what I mean. Thank you guys!

Have a look at this answer: print spaces with String.format(). — Alex

String a = "bar";
String b ="foo";
int numspace = 10;
String space = String.format("%"+ numspace +"s", " ");

     System.out.printf("%s %s %s", b,space, a);
