如何在字符串中包含变量? [英] How to including variables within strings?

问题描述

所以，我们都应该知道你可以通过以下方式将变量包含到字符串中:

So, we all should know that you can include variables into strings by doing:

String string = "A string " + aVariable;

有没有办法做到这一点:

Is there a way to do it like:

String string = "A string {aVariable}";

换句话说:无需关闭引号并添加加号.太不吸引人了.

In other words: Without having to close the quotation marks and adding plus signs. It's very unattractive.

推荐答案

您始终可以使用 String.format(....).即，

You can always use String.format(....). i.e.,

String string = String.format("A String %s %2d", aStringVar, anIntVar);

我不确定这对您是否足够有吸引力，但它可能非常方便.语法与 printf 和 java.util.Formatter 相同.我经常使用它，特别是如果我想显示表格数字数据.

I'm not sure if that is attractive enough for you, but it can be quite handy. The syntax is the same as for printf and java.util.Formatter. I've used it much especially if I want to show tabular numeric data.
