Question

我想将状态消息打印到Console中。

   System.out.format("%-60s%10s\n", "Status 1", "[Success]");
            System.out.format("%-60s%10s\n", "Status 2", "[Failed]");
            System.out.format("%-60s%10s\n", "Status 2", "[Failed]");
            System.out.format("%-60s%10s\n", "Status 2 and some text", "[Failed]");
            System.out.format("%-60s%10s\n", "Status 2", "[Failed]");
            System.out.format("%-60s%10s\n", "Status 2", "[Success]");
            System.out.format("%-60s%10s\n", "Status 2 and some very long text", "[Failed]");
            System.out.format("%-60s%10s\n", "Status 2", "[Success]");
            System.out.format("%-60s%10s\n", "Status 2 and some very very very long text", "[Failed]");
            System.out.format("%-60s%10s\n", "Status 2", "[Success]");
            System.out.format("%-60s%10s\n", "Status 2", "[Failed]");

但正如您所看到的，第二列消息格式不正确。

Status 1                                                     [Success]
Status 2                                                      [Failed]
Status 2                                                      [Failed]
Status 2 and some text                                        [Failed]
Status 2                                                      [Failed]
Status 2                                                     [Success]
Status 2 and some very long text                              [Failed]
Status 2                                                     [Success]
Status 2 and some very very very long text                    [Failed]
Status 2                                                     [Success]
Status 2                                                      [Failed]

我想打印这样的消息：

Status 1                                                      [Success]
Status 2                                                      [Failed]
Status 2                                                      [Failed]
Status 2 and some text                                        [Failed]
Status 2                                                      [Failed]
Status 2                                                      [Success]
Status 2 and some very long text                              [Failed]
Status 2                                                      [Success]
Status 2 and some very very very long text                    [Failed]
Status 2                                                      [Success]
Status 2                                                      [Failed]

我怎么能这样做？

Answer 1

为什么不添加"-"使最后一个字段左对齐，作为第一个字段？我想"%-60s%-10s\n"会起作用。

Answer 2

您可以尝试此代码

  System.out.format("%-60s%.10s\n", "Status 1", "[Success]");
    System.out.format("%-60s%.10s\n", "Status 2", "[Failed]");
    System.out.format("%-60s%.10s\n", "Status 2", "[Failed]");
    System.out.format("%-60s%.10s\n", "Status 2 and some text", "[Failed]");
    System.out.format("%-60s%.10s\n", "Status 2", "[Failed]");
    System.out.format("%-60s%.10s\n", "Status 2", "[Success]");
    System.out.format("%-60s%.10s\n", "Status 2 and some very long text", "[Failed]");
    System.out.format("%-60s%.10s\n", "Status 2", "[Success]");
    System.out.format("%-60s%.10s\n", "Status 2 and some very very very long text", "[Failed]");
    System.out.format("%-60s%.10s\n", "Status 2", "[Success]");
    System.out.format("%-60s%.10s\n", "Status 2", "[Failed]");

在java中格式化字符串
