Java Short equals()方法

java.lang.Short.equals()?方法比較此對(duì)象與指定對(duì)象。其結(jié)果是true，當(dāng)且僅當(dāng)參數(shù)不為null，并且包含相同的short值作為此short 對(duì)象。

1 語(yǔ)法

public boolean equals(Object obj)

2 參數(shù)

obj ：這是要比較的對(duì)象。

3 返回值

如果對(duì)象是相同此方法返回true，否則返回false。

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);

}

}

輸出結(jié)果為：

shortObj1 and shortObj3 have same value : false

shortObj1 and shortObj2 have same value : true

總結(jié)
