我需要转义 ( 字符，而不让输出变成其他内容，以下是任意输入和期望输出:
"a" + "\n" + "(" + "b"
期望输出:
a
b
非常感谢您的帮助！
//Here are the attempted work-arounds that failed
40 String test = "a"+"\n("+"b";
41 String[] testSplitted = test.split("\n"+"(");
42 System.out.println(testSplitted[0]);
43 System.out.println(testSplitted[1]);
// ("\n"+"\(") ILLEGAL ESCAPE CHARACTER
// ("\n\(") ILLEGAL ESCAPE CHARACTER
// ("\n(") INVALID REGULAR EXPRESSION: UNCLOSED GROUP
// ("\n\\(") Output: a \(b (Desired Output: a b)
// ("\n"+"[(]") Output:
a [(]b Exception in thread "main" java.lang.ArrayIndexOutOfBoundsException: 1
at inputhandler.InputHandler.main(InputHandler.java:43)
Java Result: 1
// ("\n"+"(") Output:
Exception in thread "main" java.util.regex.PatternSyntaxException: Unclosed group near index 2
