PatternSyntaxException when trying to split by}, {

Question

I am trying to split the array that I received through the API on the site that Java received as String .

 String[] ex = exampleString.split("},{"); 

A PatternSyntaxException . For some reason, I really don't like it },{ . I tried to run away from him as \{ but he says this is an illegal exit.

What is the correct way to avoid this line?

Answer 1

For some reason, I really don't like it}, {.

This is because curly braces ( } and { ) are special characters in Java regular expressions. If you try to use them literally without escaping, it will consider a syntax error, hence your exception.

Also avoid backslashes by doubling them. This is for the Java escape sequence. Torn backslashes will then escape the brackets for regex.

 String[] ex = exampleString.split("\\},\\{");
