例子 (Example)

以下示例显示了java.lang.Short.equals（）方法的用法。

package com.iowiki;
import java.lang.*;
public class ShortDemo {
   public static void main(String[] args) {
      // create short object and assign value to it
      short shortNum1 = 200, shortNum2 = 200, shortNum3 = 50;
      Short ShortObj1 = new Short(shortNum1);
      Short ShortObj2 = new Short(shortNum2);
      Short ShortObj3 = new Short(shortNum3);
      // returs false as both object contains different short value
      boolean val = ShortObj1.equals(ShortObj3); 
      System.out.println("shortObj1 and shortObj3 have same value : " + val);
      // returns true as both object contains same short value
      val = ShortObj1.equals(ShortObj2); 
      System.out.println("shortObj1 and shortObj2 have same value : " + val);
   }
}  

让我们编译并运行上面的程序，这将产生以下结果 -

shortObj1 and shortObj3 have same value : false
shortObj1 and shortObj2 have same value : true
