For format specifier, import the following package −

Create a formatter object and set space format specifier −

Formatter f = new Formatter();
f.format("% d", -50);
System.out.println(f);
f = new Formatter();
f.format("% d", 90);
System.out.println(f);
f = new Formatter();
f.format("%10d", -50);
System.out.println(f);
f = new Formatter();
f.format("% 10d", 90);
System.out.println(f);

      System.out.println(f);
      f = new Formatter();
      f.format("%10d", -50);
      System.out.println(f);
      f = new Formatter();
      f.format("% 10d", 90);
      System.out.println(f);
      f = new Formatter();
      f.format("%12.2f", -7.598);
      System.out.println(f);
      f = new Formatter();
      f.format("% 12.3f", 90.87787);
      System.out.println(f);
