如何在Java中使用String.format（）复制选项卡“ t”？

考虑为长度说明符使用负数：

%-20s

   public static void main(String[] args) {     String[] firstNames = {"Pete", "Jon", "Fred"};     String[] lastNames = {"Klein", "Jones", "Flinstone"};     String phoneNumber = "555-123-4567";      for (int i = 0; i < firstNames.length; i++) {        String foo = String.format("%-20s %s", lastNames[i] + ", " +   firstNames[i], phoneNumber);        System.out.println(foo);      }      }
