简短的类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()方法用于在数学上检查给定Short对象与此给定Short对象的相等性或不相等性，换句话说，可以说此方法用于比较两个Short对象。

• 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()方法是一种非静态方法，只能通过类对象访问，如果尝试使用类名称访问该方法，则会收到错误消息。

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

  在比较Short对象时， compareTo()方法不会引发异常。

Syntax:

句法：

    public int compareTo(Short value2);

Parameter(s):

参数：

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

  短值2 –表示要比较的短对象。

Return value:

返回值：

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

此方法的返回类型为int ，它基于以下情况返回整数值：

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

  如果value1在数学上等于value2 ，则返回0 。

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

  如果value1在数学上小于value2 ，则返回值<0 。

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

  如果value1在数学上大于value2，则它返回> 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

输出量

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