推荐答案
您的意思是"["和]"?
整理出来.
类 Java.lang.String [ ^ ]包含用于
- String.indexOf(字符串) [ String.replaceAll(String,String) [
You mean "[" and "]" ??
Sort them out.
the class Java.lang.String[^] contains methods for
- String.indexOf(String)[^] which returns a positive natural number if it found some or -1 when not.
- String.replaceAll(String, String)[^] to replace a certain expression in a String.
Be aware that those functions return the new formatted String.
