Java中字符串按逗号分开成为String数组

import java.util.Scanner;
public class Test {
public static void main(String[] args) {
int i,n=0;
String[] words;
Scanner sc=new Scanner(System.in);
System.out.println ("请输入一串数字，以逗号隔开:");
String str=sc.next();
for(i=0;iif(str.charAt(i)==',') n++;
}
words=str.trim().split(",");
for(i=0; iSystem.out.print(words[i]+"\t");
}
}
}

public String[] strToArray(String str) {
StringTokenizer st = new StringTokenizer(str, ",");
String[] strArray = new String[st.countTokens()];
int strLeng = st.countTokens();

for (int i=0; i strArray[i] = st.nextToken();

}
return strArray;
}

试试好用吗。
