java.lang.Short.compareTo()方法範例

java.lang.Short.compareTo() 方法比較兩個Short物件的數值。

宣告

以下是java.lang.Short.compareTo()方法的宣告

public int compareTo(Short anotherShort)

引數

• anotherShort -- 這是要比較Short。

返回值

此方法返回值0，如果該Short等於引數Short；值小於0 如果該Short數值比引數Short小；如果該Short數值小於引數Short更大返回值大於0。

異常

• NA

例子

下面的例子顯示java.lang.Short.compareTo()方法的使用。

package com.yiibai;

import java.lang.*;

public class ShortDemo {

   public static void main(String[] args) {
   
     // create short object and assign value to it
     short val1 = 50, val2 = 200, val3 = 50;
     Short Shortval1 = new Short(val1);
     Short Shortval2 = new Short(val2);
     Short Shortval3 = new Short(val3);
    
     // returns less than 0 if this Short is less than the argument Short
     int cmp = Shortval1.compareTo(Shortval2); 
     System.out.println("" + Shortval1 + " is less than " + Shortval2 + ",
     difference = " + cmp);

     // returns 0 if this Short is equal to the argument Short
     cmp = Shortval1.compareTo(Shortval3); 
     System.out.println("" + Shortval1 + " is equal to " + Shortval3 + ",
     difference = " + cmp);

     // returns greater than if this Short is greater than the argument Short
     cmp = Shortval2.compareTo(Shortval1); 
     System.out.println("" + Shortval2 + " is more than " + Shortval1 + ",
     difference = " + cmp);
  }
}   

讓我們來編譯和執行上面的程式，這將產生以下結果：

50 is less than 200, difference = -150
50 is equal to 50, difference = 0
200 is more than 50, difference = 150
