commons-text StrBuilder字符串构建工具类例子

package com.skylink.junge.demo;

import java.util.ArrayList;
import java.util.List;

import org.apache.commons.text.StrBuilder;

public class StrBuilderTest {

    public static void main(String[] args) {
        String[] strs = new String[]{"111", "222", "333"};
        StrBuilder strBuilder = new StrBuilder();
        System.out.println(strBuilder.appendWithSeparators(strs, ","));
        
        List<String> strList = new ArrayList<String>(3);
        strList.add("444");
        strList.add("555");
        strList.add("666");
        
        strBuilder.clear();
        System.out.println(strBuilder.appendWithSeparators(strList, ","));
    }

}

运行结果：

使用场景：可以再拼接sql条件时使用。
