Java Short valueOf()方法

java.lang.Short.valueOf(String s, int radix) 方法返回保持从指定的String中提取的值，由第二个参数给出的基数进行分析short的对象。

1 语法

public static Short valueOf(String s, int radix) throws NumberFormatException

2 参数

s ：这是要被解析的字符串。

radix： 这是要解释s至使用的进制

3 返回值

此方法返回保存由指定基数的字符串参数表示的值的Short对象。

public class ShortDemo {

   public static void main(String[] args) {

     short shortNum = 100;
     String str = "1000";
    
     // returns Short object representing given short value
     Short ShortValue = Short.valueOf(shortNum);
     // displays the short object value
     System.out.println("Short object representing the specified short value =
     " + ShortValue);
     
     // returns a Short object holding the value given by the specified String
     ShortValue = Short.valueOf(str); 
     // displays the short object value
     System.out.println("Short object holding the value given by the specified
     String = " + ShortValue); 
   
     /* returns a Short object holding the value from the specified String
     according to radix. */
     ShortValue = Short.valueOf(str , 2) ;
     // displays the short object value
     System.out.println("Short object value for specified String with radix 2
     =" + ShortValue);
    
     // returns a Short object holding the value for string to radix   
     ShortValue = Short.valueOf("15" , 8) ;
     // displays the short object value
     System.out.println("Short object value String 15 with radix 8
     = " + ShortValue);
  }
}

输出结果为：

Short object representing the specified short value = 100
Short object holding the value given by the specified String = 1000
Short object value for specified String with radix 2 = 8
Short object value String 15 with radix 8 = 13
