记事本++的nppexec中的java\t间距

Question

我用java“CircleDemo”编写了一个程序，不可避免地会这样做：

System.out.printf("The circle's area \t   is \t %.2f \n", circle.getArea());
System.out.printf("The circle's diameter \t   is \t %.2f \n", circle.getDiameter());
System.out.printf("The circle's circumference is \t %.2f \n", circle.getCircumference());

在cmd中。exe显示如下所示：

The circle's area          is    3.14 
The circle's diameter      is    2.00
The circle's circumference is    6.28

漂亮、干净的格式

但是，Notepad++的控制台（nppexec）打印的程序如下所示：

The circle's area     is    3.14 
The circle's diameter      is    2.00
The circle's circumference is    6.28

您可以看到格式是如何不同的。现在，我已经玩了足够长的时间，以找到导致这一点的原因是“\t”在cmd中以不同的方式打印选项卡。exe与Notepad++的nppexec

如何编辑nppexec的“\t”格式以打印与cmd相同的“\t”。你会吗

Answer 1

避免使用\t获取数组格式。我可能会简单地使用

System.out.printf("The circle's area          is %.2f %n", circle.getArea() );
System.out.printf("The circle's diameter      is %.2f %n", circle.getDiameter());
System.out.printf("The circle's circumference is %.2f %n", circle.getCircumference());

如果需要更动态的解决方案，您可以使用

System.out.printf("The circle's %-13s is %.2f%n", "area", circle.getArea());

或者如果响应不需要总是以The circle's开头

System.out.printf("%-26s is %.2f%n", "The circle's area",  circle.getArea());

你可以试试下面的例子。务必在宽度前使用“-”，以确保左缩进。默认情况下，它们将右缩进；这可能不符合你的目的

    System.out.printf("%-30s %-5s $%.2f\n","The circle's area ", "is" ,circle.getArea());
    System.out.printf("%-30s %-5s $%.2f\n","The circle's diameter ", "is" ,circle.getDiameter());
    System.out.printf("%-30s %-5s $%.2f\n","The circle's circumference ", "is" ,circle.getCircumference());
