Update:

The actual formatting commands depend on the data you are printing, the exact spacing you want, etc. Here's one of many possible examples:

System.out.printf("%1s  %-7s   %-7s   %-6s   %-6s%n", "n", "result1", "result2", "time1", "time2");
System.out.printf("%1d  %7.2f   %7.1f   %4dms   %4dms%n", 5, 1000F, 20000F, 1000, 1250);
System.out.printf("%1d  %7.2f   %7.1f   %4dms   %4dms%n", 6, 300F, 700F, 200, 950);
