短類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對象的哈希碼。
• 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()方法是一個非靜態(tài)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。
• hashCode() method does not throw an exception at the time of returning hash code.hashCode()方法在返回哈希碼時不會引發(fā)異常。

Syntax:

句法：

public int hashCode();

Parameter(s):

參數(shù)：

• It does not accept any parameter.
  它不接受任何參數(shù)。

Return value:

返回值：

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

此方法的返回類型為int ，它返回此對象的哈希碼。

Example:

例：

// Java program to demonstrate the example // of int hashCode() method of Short classpublic class HashCodeOfShortClass {public static void main(String[] args) {// Variables initializationshort 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 resultSystem.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 resultSystem.out.println("ob2.hashCode(): " + ob2.hashCode());} }

Output

輸出量

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