How can I add escape characters to a Java String?
提问by Jigglypuff
If I had a string variable:
如果我有一个字符串变量：
String example = "Hello, I'm here";
and I wanted to add an escape character in front of every 'and "within the variable(i.e. notactually escape the characters), how would I do that?
并且我想在每个变量的前面'和"内部添加一个转义字符（即实际上不是对字符进行转义），我该怎么做？

I'm not claiming elegance here, but i thinkit does what you want it to do (please correct me if I'm mistaken):
我不是在这里声称优雅，但我认为它可以做你想做的事情（如果我错了，请纠正我）：
public static void main(String[] args)
{
String example = "Hello, I'm\" here";
example = example.replaceAll("'", "\\'");
example = example.replaceAll("\"", "\\\"");
System.out.println(example);
}
outputs
产出
Hello, I\'m\" here
