扫描器类的nextShort()方法 (Scanner Class nextShort() method)

Syntax:

句法：

    public short nextShort();
public short nextShort(int rad);

• nextShort() method is available in java.util package.

  nextShort()方法在java.util包中可用。

• nextShort() method is used to read the next token of the input as a short value at the implicit radix of this Scanner.

  nextShort()方法用于读取输入的下一个标记，作为此Scanner隐式基数处的短值。

• nextShort(int rad) method is used to read the next token of the input as a short value at the explicit or given radix(rad) of this Scanner.

  nextShort(int rad)方法用于读取输入的下一个标记作为此Scanner的显式或给定基数(rad)的短值。

• These methods may throw an exception at the time of representing an input as a short value.

  这些方法在将输入表示为短值时可能会引发异常。

  • InputMismatchException: This exception may throw when the next token of the input mismatch.InputMismatchException ：当输入的下一个标记不匹配时，可能引发此异常。
  • NoSuchElementException: This exception may throw when no such element exists.NoSuchElementException ：如果不存在这样的元素，则可能引发此异常。
  • IllegalStateException: This exception may throw when this Scanner is not opened.IllegalStateException ：如果未打开此扫描器，则可能引发此异常。

• These are non-static methods and it is accessible with the class object only and if we try to access these methods with the class name then we will get an error.

  这些是非静态方法，只能通过类对象访问，如果尝试使用类名称访问这些方法，则会收到错误消息。

Parameter(s):

参数：

• In the first case, nextShort(),

  在第一种情况下， nextShort() ，

  • It does not accept any parameter.

• In the second case, nextShort(int rad),

  在第二种情况下， nextShort(int rad) ，

  • int rad – represents the radix used to manipulate the token as a short value.
  • int rad –表示用于操纵令牌的基数(短值)。

Return value:

返回值：

In both the cases, the return type of the method is short, it retrieves the short value read from the input.

在这两种情况下，方法的返回类型均为short ，它检索从输入中读取的short值。

Example 1:

范例1：

// Java program to demonstrate the example 
// of nextShort() method of Scanner
import java.util.*;
import java.util.regex.*;
public class NextShort {
public static void main(String[] args) {
String str = "Java Programming! 3 * 8= 24 + sh";
short sh = 1012;
// Instantiates Scanner
Scanner sc = new Scanner(str);
while (sc.hasNext()) {
// By using nextShort() method isto
// return the next token as a 
// short at the implicit radix
if (sc.hasNextShort()) {
short next_s = sc.nextShort();
System.out.println("sc.nextShort()): " + next_s);
}
System.out.println(sc.next());
}
// Scanner closed
sc.close();
}
}

Output

Example 2:

范例2：

import java.util.*;
import java.util.regex.*;
public class NextShort {
public static void main(String[] args) {
String str = "Java Programming! 3 * 8= 24 + sh";
short sh = 1012;
// Instantiates Scanner
Scanner sc = new Scanner(str);
while (sc.hasNext()) {
// By using nextShort(9) method isto
// return the next token as a 
// short at the explicit radix
if (sc.hasNextShort()) {
short next_s = sc.nextShort(9);
System.out.println("sc.nextShort(9)): " + next_s);
}
System.out.println(sc.next());
}
// Scanner closed
sc.close();
}
}

Output
