将两个逗号分隔的字符串转换为地图

Question

我有两个逗号分隔的字符串。我希望通过按索引绑定值索引来将这些值放入地图中。一种方法是使用以下示例：

package com.test; 

import java.util.ArrayList; 
import java.util.Arrays; 
import java.util.HashMap; 
import java.util.List; 
import java.util.Map; 

public class StringToMap { 

    public static void main(String[] args) { 
     String s1 = "1, 2, 3"; 
     String s2 = "a, b, c"; 
     Map<String, String> m = new HashMap<String, String>(); 

     List<String> s1List = new ArrayList<String>(Arrays.asList(s1.split(","))); 
     List<String> s2List = new ArrayList<String>(Arrays.asList(s2.split(","))); 

     for (int i = 0; i < s1List.size(); i++) { 
      m.put(s1List.get(i).trim(), s2List.get(i).trim()); 
     } 

     System.out.println(m); 
    } 
} 

结果是：{3 = c，2 = b，1 = a}。有没有其他有效/最好的方法来做到这一点？

您对此有何看法？

public static void main(String[] args) { 
    String s1 = "1, 2, 3"; 
    String s2 = "a, b, c"; 
    Map<String, String> m = new HashMap<String, String>(); 
    String s1List [] = s1.split(","); 
    String s2List [] = s2.split(","); 
    for (int i = 0; i < s1List.length && i < s2List.length; i++) { 
     m.put(s1List[i].trim(), s2List[i].trim()); 
    } 
    System.out.println(m); 
}
