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異常。
Syntax:
句法：
public int hashCode();
Parameter(s):
參數：
- It does not accept any parameter. 它不接受任何參數。
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 class
public 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
輸出量
ob1.hashCode(): 30
ob2.hashCode(): 10
