split("\") and error

Question

``` String str = "\u0054\u0068\u0069\u006e\u006b\u0050\u0061\u0064"; String[] strArray = str.split("\"); ``` but this error occured. Exception in thread "main" java.util.regex.PatternSyntaxException: Unexpected internal error near index 1

Accepted Answer

it should be

```
String[] strArray = str.split("\\");
```

the reason why is because in `Regex`, `\` has special meaning so you need to escape it into `\`.

and in java, `\` should be equal to `"\\"`

split("\\") and error
