簡短的類compareTo()方法 (Short class compareTo() method)

• compareTo() method is available in java.lang package.

  compareTo()方法在java.lang包中可用。

• compareTo() method is used to check equality or inequality for this Short object against the given Short object mathematically or in other words, we can say this method is used to compare two Short objects.

  compareTo()方法用于在數學上檢查給定Short對象與此給定Short對象的相等性或不相等性，換句話說，可以說此方法用于比較兩個Short對象。

• compareTo() method is a non-static method, it is accessible with the class object only and if we try to access the method with the class name then we will get an error.

  compareTo()方法是一種非靜態方法，只能通過類對象訪問，如果嘗試使用類名稱訪問該方法，則會收到錯誤消息。

• compareTo() method does not throw an exception at the time of comparing the Short object.

  在比較Short對象時， compareTo()方法不會引發異常。

Syntax:

句法：

    public int compareTo(Short value2);

Parameter(s):

參數：

• Short value2 – represents the Short object to compare with.

  短值2 –表示要比較的短對象。

Return value:

返回值：

The return type of this method is int, it returns an integer value based on the following cases,

此方法的返回類型為int ，它基于以下情況返回整數值：

• It returns 0 if value1 is mathematically equal to value2.

  如果value1在數學上等于value2 ，則返回0 。

• It returns the value < 0 if value1 is mathematically less than value2.

  如果value1在數學上小于value2 ，則返回值<0 。

• It returns the value > 0 if value1 is mathematically greater than value2.

  如果value1在數學上大于value2，則它返回> 0的 值 。

Example:

例：

// Java program to demonstrate the example 
// of compareTo(Short value2) method of  Short class
public class CompareToOfShortClass {
public static void main(String[] args) {
// Variables initialization
short s1 = 10;
short s2 = 20;
// Short instance 
Short value1 = new Short(s1);
Short value2 = new Short(s2);
// It compare two Short objects and placed the 
// result in another variable (compare) of integer type
int compare = value1.compareTo(value2);
// Display result
System.out.println("value1.compareTo(value2): " + compare);
System.out.println();
if (compare == 0)
System.out.println("value1 is equal to value2");
else if (compare < 0)
System.out.println("value1 is less than value2");
else
System.out.println("value1 is greater than value2");
}
}

Output

輸出量

value1.compareTo(value2): -10value1 is less than value2
