System.out.printf和String.format之间的区别 [英] Difference between System.out.printf and String.format

问题描述

我可以知道两者在Java中有什么区别吗?我正在读一本书，它同时使用两种方法来显示字符串.

May I know what is the difference between the two in java? I am reading a book and it uses both methods to display strings.

推荐答案

The first one writes to the stdout and the second one returns a String object.

使用哪种取决于唯一目的.如果要在标准输出(控制台)中显示字符串，请使用第一个.如果要获取格式化字符串的句柄以在代码中进一步使用，请使用第二个.

Which to use depends on the sole purpose. If you want to display the string in the stdout (console), then use the first. If you want to get a handle to the formatted string to use further in the code, then use the second.
