java - 在 java 中使用字符串格式打印列

Question

我尝试用 java 打印输出结果是这样的

---------------------------------
             qty   price   code
Coffee       2     12.000    T1
Tea          1     10.000    T1
Orange Juice 1     15.000    T1
Pineapple    1     20.000    T1
Juice
Tap Water    1     9000      T1
---------------------------------

到目前为止，这是我的代码

    System.out.print("\n");
    System.out.print("--------------------------------");
    System.out.print("\n");
    System.out.print(String.format("%-12s %-5s %-7s %-4s\n","","qty","price","code"));
    System.out.print("-------------------------------\n");
    System.out.print(String.format("%-12s %-5s %-7s %4s\n","Coffee","2","12.000","T1"));
    System.out.print(String.format("%-12s %-5s %-7s %4s\n","Tea","1","10.000","T1"));
    System.out.print(String.format("%-12s %-5s %-7s %4s\n","Orange Juice","1","15.000","T1"));
    System.out.print(String.format("%-12s %-5s %-7s %4s\n","Pineapple Juice","1","20.000","T1"));
    System.out.print(String.format("%-12s %-5s %-7s %4s\n","Tap Water","1","9000","T1"));
    System.out.print("--------------------------------");
    System.out.print("\n");

代码的输出是

---------------------------------
             qty   price   code
Coffee       2     12.000    T1
Tea          1     10.000    T1
Orange Juice 1     15.000    T1
Pineapple Juice 1     20.000    T1
Tap Water    1     9000      T1
---------------------------------

有谁知道如何修改我的代码以便我可以按我想要的方式打印:)

System.out.print("\n");
    System.out.print("--------------------------------");
    System.out.print("\n");
    System.out.print(String.format("%-15s %-5s %-7s %-4s\n","","qty","price","code"));
    System.out.print("-------------------------------\n");
    System.out.print(String.format("%-15s %-5s %-7s %4s\n","Coffee","2","12.000","T1"));
    System.out.print(String.format("%-15s %-5s %-7s %4s\n","Tea","1","10.000","T1"));
    System.out.print(String.format("%-15s %-5s %-7s %4s\n","Orange Juice","1","15.000","T1"));
    System.out.print(String.format("%-15s %-5s %-7s %4s\n","Pineapple Juice","1","20.000","T1"));
    System.out.print(String.format("%-15s %-5s %-7s %4s\n","Tap Water","1","9000","T1"));
    System.out.print("--------------------------------");
    System.out.print("\n");

因为 Pineapple Juice 的长度比其他的多，所以留了 15s 的空格，希望对您有所帮助
