java bitset_Java BitSet hashCode()方法及示例
java bitset
BitSet類hashCode()方法 (BitSet Class hashCode() method)
hashCode() method is available in java.util package.
hashCode()方法在java.util包中可用。
hashCode() method is used to retrieve hash code for this bit set (BitSet).
hashCode()方法用于檢索此位集(BitSet)的哈希碼。
hashCode() method is a non-static method, so it is accessible with the class object and if we try to access the method with the class name then we will get an error.
hashCode()方法是一種非靜態方法,因此可以通過類對象進行訪問,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 retrieving hash code.
hashCode()方法在檢索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 value for this BitSet.
此方法的返回類型為int ,它返回此BitSet的哈希碼值。
Example:
例:
// Java program to demonstrate the example // of int hashCode() method of BitSet.import java.util.*;public class HashCodeOfBitSet {public static void main(String[] args) {// create an object of BitSetBitSet bs = new BitSet(10);// By using set() method is to set// the values in BitSet bs.set(10);bs.set(20);bs.set(30);bs.set(40);bs.set(50);// Display BitsetSystem.out.println("bs: " + bs);// By using hashCode() method is to return// the hash code of this BitSetint hc = bs.hashCode();// Display hash code of bsSystem.out.println("bs.hashCode(): " + hc);} }Output
輸出量
bs: {10, 20, 30, 40, 50} bs.hashCode(): 1075053010翻譯自: https://www.includehelp.com/java/bitset-hashcode-method-with-example.aspx
