短类hashCode()方法 (Short class hashCode() method)

• hashCode() method is available in java.lang package.
• hashCode()方法在java.lang包中可用。
• hashCode() method is used to return hashcode of the Short object.hashCode()方法用于返回Short对象的哈希码。
• hashCode() 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.hashCode()方法是一个非静态方法，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。
• hashCode() method does not throw an exception at the time of returning hash code.hashCode()方法在返回哈希码时不会引发异常。

Syntax:

句法：

public int hashCode();

Parameter(s):

参数：

• It does not accept any parameter.
  它不接受任何参数。

Return value:

返回值：

The return type of this method is int, it returns hash code for this object.

此方法的返回类型为int ，它返回此对象的哈希码。

Example:

例：

// Java program to demonstrate the example // of int hashCode() method of Short classpublic class HashCodeOfShortClass {
       public static void main(String[] args) {
           // Variables initialization        short value1 = 30;        short value2 = 10;        // It returns hashcode value denoted by this Short ob1 object        // by calling ob1.hashCode()        Short ob1 = new Short(value1);        // Display ob1 result        System.out.println("ob1.hashCode(): " + ob1.hashCode());        // It returns hashcode value denoted by this Short ob2 object        // by calling ob2.hashCode()        Short ob2 = new Short(value2);        // Display ob2 result        System.out.println("ob2.hashCode(): " + ob2.hashCode());    }}

Output

输出量

ob1.hashCode(): 30ob2.hashCode(): 10
