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 Byte object.

  hashCode()方法用于返回Byte對(duì)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(gè)非靜態(tài)方法，只能通過類對(duì)象訪問，如果嘗試使用類名稱訪問該方法，則會(huì)收到錯(cuò)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(shí)不會(huì)引發(fā)異常。

Syntax:

句法：

public short 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 the hash code for this object.

此方法的返回類型為int ，它返回此對(duì)象的哈希碼。

Example:

例：

// Java program to demonstrate the example // of int hashCode() method of Byte classpublic class HashCodeOfByteClass {public static void main(String[] args) {// Variables initializationbyte value1 = 30;byte value2 = 10;// It returns hashcode value denoted by this Byte b1 object// by calling b1.hashCode()Byte b1 = new Byte(value1);// Display b1 resultSystem.out.println("b1.hashCode(): " + b1.hashCode());// It returns hashcode value denoted by this Byte b2 object// by calling b2.hashCode()Byte b2 = new Byte(value2);// Display b2 resultSystem.out.println("b2.hashCode(): " + b2.hashCode());} }

Output

輸出量

b1.hashCode(): 30 b2.hashCode(): 10
