如何将转义字符添加到Java字符串？ [英] How can I add escape characters to a Java String?

问题描述

如果我有一个字符串变量：

If I had a string variable:

String example = "Hello, I'm here";

我想在每个'前添加一个转义字符和 变量（即不实际转义字符），我该怎么做那个？

and I wanted to add an escape character in front of every ' and " within the variable (i.e. not actually escape the characters), how would I do that?

推荐答案

我不会在这里声称优雅，但我认为它会做你想要的它要做（请纠正我，如果我错了）：

I'm not claiming elegance here, but i think it does what you want it to do (please correct me if I'm mistaken):

public static void main(String[] args)
{
    String example = "Hello, I'm\" here";
    example = example.replaceAll("'", "\\\\'");
    example = example.replaceAll("\"", "\\\\\"");
    System.out.println(example);
}

输出

Hello, I\'m\" here
