java - Stringtokenizer 未定义

Question

您好，我在制作 stringtokenizer 方法时遇到了一些问题，该方法允许用户输入字符串并计算和打印标记。有人可以帮我解决错误吗？它说构造函数未定义。

public class StringTokenizer
{
  public static void main(String[ ] args)
  {
      Scanner keyboard;
      String inputSentence;
      StringTokenizer stok = null; //declare a reference to hold the address of a StringTokenizer object
      keyboard = new Scanner(System.in);

      System.out.println("Enter a line of text: ");
      inputSentence = new String(keyboard.nextLine( ) );
      while(!(inputSentence.equals("quit")))
      {
          stok = new StringTokenizer(inputSentence);//the constructor that take a String and uses a space as the delimeter
          while (stok.hasMoreTokens());
          {
          System.out.println("Number of tokens: " + stok.countTokens( ));
          System.out.println(stok.nextToken( ));
          }




        System.out.println("Enter another line of data or quit\n" );
        inputSentence = keyboard.nextLine( );

    }
    System.out.println("Goodbye");



    }//end of main
} //end of class

重命名您的 类。您正在跟踪 java.util.StringTokenizer；或者，

java.util.StringTokenizer stok = null;

和

stok = new java.util.StringTokenizer(inputSentence);

但是，如果您重命名您的类，就不会那么困惑了。
