Java StringTokenizer hasMoreTokens()用法及代码示例

StringTokenizer类的hasMoreTokens()方法检查此StringTokenizer是否还有可用的令牌。

用法:

public boolean hasMoreTokens()

参数：该方法不带任何参数。

返回值：如果在当前位置之后在字符串中找到至少一个以上的令牌，则该方法返回boolean True。

下面的程序说明StringTokenizer的hasMoreTokens()方法的用法：
示例1:

// Java code to illustrate hasMoreTokens() method 
  
import java.util.*; 
  
public class StringTokenizer_Demo { 
    public static void main(String args[]) 
    { 
        // Creating a StringTokenizer 
        StringTokenizer str_arr 
            = new StringTokenizer( 
                "Lets practice at GeeksforGeeks"); 
  
        // Counting the tokens 
        System.out.println("The number of Tokens are: "
                           + str_arr.countTokens()); 
  
        // Checking for any tokens 
        System.out.println(str_arr.hasMoreTokens()); 
  
        // Checking and displaying the Tokens 
        while (str_arr.hasMoreTokens()) { 
            System.out.println("The Next token: "
                               + str_arr.nextToken()); 
        } 
    } 
}

输出：

The number of Tokens are: 4
true
The Next token: Lets
The Next token: practice
The Next token: at
The Next token: GeeksforGeeks

示例2:

// Java code to illustrate hasMoreTokens() method 
  
import java.util.*; 
  
public class StringTokenizer_Demo { 
    public static void main(String args[]) 
    { 
        // Creating a StringTokenizer 
        StringTokenizer str_arr 
            = new StringTokenizer(""); 
  
        // Counting the tokens 
        System.out.println("The number of Tokens are: "
                           + str_arr.countTokens()); 
  
        // Checking for any tokens 
        System.out.println(str_arr.hasMoreTokens()); 
    } 
}

输出：

The number of Tokens are: 0
false
