如何把一段逗号分割的字符串转换成一个数组?

public class StrSplit2{
    public static void main(String[] args) {
        String orgStr="a,b,c,d,e,f";  
        String [] result = orgStr.split(",");
        
        for(int a = 0;a<result.length;a++){
           System.out.print(result[a]+"\t");
        }
    }
}

import java.util.StringTokenizer;
//方案二：
public class StrSplit{
    public static void main(String[] args) {
        
        String orgStr="ab,b,c,d,e,f";  
        StringTokenizer  tokener = new StringTokenizer(orgStr,",");
        String [] result = new String[tokener .countTokens()];
          
        int i=0;
        while(tokener. hasMoreTokens ())
             {
               result[i++]=tokener.nextToken();
             }
        for(int a = 0;a<result.length;a++){
           System.out.print(result[a]+"\t");
        }
    }
}
