如何使用REGEX在分度内的每个字符串后打印：|：模式

Question

Suppose i have a string "[cat]:|:[]:|:[dog]:|:[cow]:|:[]:|:[]:|:[monkey]" like this. I am able to print [cat][dog][cow][monkey] from the above string. How can i print something like this = [cat]:|:[dog]:|:[cow]:|:[monkey] . please help.

import java.util.regex.*;
public class RegexMain {

        static final String PATTERN = "\\[([^]]+)\\]|\"[^\"]*\"";
        static final Pattern CONTENT = Pattern.compile(PATTERN);

        public static void main(String[] args) {
            String test1 = "[cat] [] [dog] [cow] []  [] [monkey]";
            Matcher match = CONTENT.matcher(test1);
            while(match.find()) {
                if(match.group(1).length() != 0) {
                System.out.print(  match.group().trim());
            }

        }
    }
}

Answer 1

I am actually not sure what your string is exactly (you are using different ones in your explanation and code). Anyways you can try this :

public static void main(String[] args) {
    String s = "[cat]:|:[]:|:[dog]:|:[cow]:|:[]:|:[]:|:[monkey]";
    System.out.println(s.replaceAll(":\\[\\]:\\|", ""));
}

O/P :

[cat]:|:[dog]:|:[cow]:|:[monkey]

怎么样

System.out.print(  match.group().trim() + ":|:");
