輸入： THIS IS A STRING PROGRAM.IS THIS EASY?YES,IT IS 。

輸出：

THIS
IS
A
STRING
PROGRAM

THIS
EASY
YES
IT

Answer 1

請參考Java中StringTokenizer類的構造函數。 它具有接受自定義分隔符的規定。

嘗試這個：

    StringTokenizer tokenizer = new StringTokenizer("THIS IS A STRING PROGRAM.IS THIS EASY?YES,IT IS", " .?");
    while (tokenizer.hasMoreElements()) {
        System.out.println(tokenizer.nextElement());
    }

Answer 2

 public static void main(String[] args) {
    String str = "THIS IS A STRING PROGRAM.IS THIS EASY?YES,IT IS";

    StringTokenizer st = new StringTokenizer(str);

    System.out.println("---- Split by space ------");
    while (st.hasMoreElements()) {
        System.out.println(st.nextElement());
    }

    System.out.println("---- Split by comma ',' ------");
    StringTokenizer st2 = new StringTokenizer(str, ",");

    while (st2.hasMoreElements()) {
        System.out.println(st2.nextElement());
    }
}
