将一个字符串一逗号为分割 组成一个数字

public class sortCC {
?public static void main(String[]args){
?? String str = "ab,cd,eeee,ffff";
/*??? String [] result = str.split(",");
?? for(String s? : result){
??? System.out.println(s);
?? }*/
??StringTokenizer st = new StringTokenizer(str,",");
??String [] strr= new String[st.countTokens()];
??int i = 0 ;
??while(st.hasMoreTokens()){
???strr[i++]=st.nextToken();
??}
???? for(String s? : strr){
????? System.out.println(s);
???? }
?}
}
