(Java) 문자열을 공백(지정문자)으로 분리하여 얻고자할때 - StringTokenizer 사용법

(1)    loop  돌려서  하나씩  꺼내는  방법
StringTokenizer  strToken  =  StringTokenizer(data," ");
while  (strToken.hasMoreTokens()){
              String  token  =  strToken.nextToken();
              System.out.println("\n"  +  token);
}

(2)  nextToken  써서  포인트를  이동하여  얻는방법
String  str  =  "안녕 하세 요";
StringTokenizer    st  =  new  StringTokenizer(str," ");
String  a  =  st.nextToken();                //  a  =  "안녕"  
String  b  =  st.nextToken();                //  b  =  "하세"
String  c  =  st.nextToken();                //  c  =  "요"
