Java中如何取出String字符串括号中的内容

package com.cnic.flink.etl.test;
import java.util.HashMap;
import java.util.Map;
public class Map2Bean {
    public static void main(String[] args) {
        String str = "[tid:2656,Q:W183CWbcBewrSgccJOdw] ";
        //String substring = str.substring(0, 10);
        //System.out.println(substring);
        //String sub001 = str.substring(0 ,10);
        //System.out.println(sub001);
        //int i = str.indexOf("[", "]");
        String substring = str.substring(str.indexOf("[")+1, str.indexOf("]"));
        System.out.println(substring);
        HashMap<String, String> map = new HashMap<String, String>();
    }
}

String input = "test data (测试)";
String output = input.substring(input.indexOf("(") + 1 ,input.indexOf(")"));
log.info("output={}", output);

    String input = "test data (测试)(data)";
    String pattern = "\\(([^\\)]+)\\)";
    Matcher matcher = Pattern.compile(pattern).matcher(input);
    while (matcher.find()) {
        String output = matcher.group(1);
        log.info("output={}", output);
    }

String input = "test data (测试)data";
String [] outs = input.split("[\\(\\)]");
log.info(outs[1]);

String input0 = "test data (测试)";
String input1 = "test data (测试)(data)";
String output = StringUtils.substringBetween(input, "(", ")");
String [] out = StringUtils.substringsBetween(input1,"(", ")");
