String Tokenizer分离

Question

我想知道我们如何分隔句子的单词，其中分隔符是''（空格）或'？' 要么 '。'。 对于前

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

输出：

THIS
IS
A
STRING
PROGRAM
IS
THIS
EASY
YES
IT
IS

Answer 1

请参阅Java中StringTokenizer类的构造函数。它可以接受自定义分隔符。

试试这个：

    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());
    }
}
