String escaped = "AAAAA\"1111".replace("\"", "\\"");
- API doc for
String.replace
- API 文档
String.replace
(Note that the replaceAllversion handles regular expressions and is an overkill for this particular situation.)
（请注意，该replaceAll版本处理正则表达式，对于这种特殊情况来说是一种矫枉过正。）

string.replace("\"", "\\\"")
string.replace("\"", "\\\"")
You want to replace "with \". Since both "and \have a specific meaning you must escape them correctly by adding a preceding \before each one.
您想替换"为\". 由于"和\都具有特定含义，因此您必须通过\在每个之前添加前缀来正确地转义它们。
So "--> \"and \"--> \\\".
And since you want the compiler to understand that this is a String, you need to wrap each string with double-quotes So "--> \"and "\""--> "\\\"".
所以"-->\"和\"--> \\\"。并且由于您希望编译器理解这是一个字符串，因此您需要用双引号 So "-->\"和"\""-->将每个字符串括起来"\\\""。

Although the other answers are correct for the single situation given, for more complicated situations, you may wish to use StringEscapeUtils.escapeJava(String)from Apache Commons Lang.
尽管其他答案对于给定的单一情况是正确的，但对于更复杂的情况，您可能希望使用Apache Commons Lang 中的StringEscapeUtils.escapeJava(String)。
String escaped = StringEscapeUtils.escapeJava(string);

System.out.println("AAAAA\"1111".replaceAll("\"", "\\\""));
