Java ConcurrentLinkedDeque hashCode()用法及代码示例

Java中ConcurrentLinkedDeque的hashCode()方法用于获取ConcurrentLinkedDeque实例的hashCode值。它返回一个整数值，该值是此ConcurrentLinkedDeque实例的hashCode值。

用法:

public int hashCode()

参数：此函数没有参数。

返回值：该方法返回一个整数值，该值是此ConcurrentLinkedDeque实例的hashCode值。

以下示例程序旨在说明ConcurrentLinkedDeque.hashCode()方法：

示例1:

// Java Program Demonstrate hashCode() 
// method of ConcurrentLinkedDeque 
  
import java.util.concurrent.ConcurrentLinkedDeque; 
import java.util.*; 
  
public class GFG { 
    public static void main(String[] args) 
        throws IllegalStateException 
    { 
  
        // create object of ConcurrentLinkedDeque 
        ConcurrentLinkedDeque<Integer> CLD 
            = new ConcurrentLinkedDeque<Integer>(); 
  
        // Add numbers to end of ConcurrentLinkedDeque 
        CLD.add(7855642); 
        CLD.add(35658786); 
        CLD.add(5278367); 
        CLD.add(74381793); 
  
        System.out.println("Linked Blocking Deque: " + CLD); 
  
        // Get the hashCode value 
        // using hashCode() value 
        System.out.println("HashCode value: "
                           + CLD.hashCode()); 
    } 
}

输出：

Linked Blocking Deque: [7855642, 35658786, 5278367, 74381793]
HashCode value: 2101973421

示例2:

// Java Program Demonstrate hashCode() 
// method of ConcurrentLinkedDeque 
// when the list contains characters 
  
import java.util.concurrent.ConcurrentLinkedDeque; 
import java.util.*; 
  
public class GFG { 
    public static void main(String[] args) 
        throws IllegalStateException 
    { 
  
        // create object of ConcurrentLinkedDeque 
        ConcurrentLinkedDeque<String> CLD 
            = new ConcurrentLinkedDeque<String>(); 
  
        // Add numbers to end of ConcurrentLinkedDeque 
        CLD.add("1"); 
        CLD.add("2"); 
        CLD.add("3"); 
        CLD.add("4"); 
  
        System.out.println("Linked Blocking Deque: " + CLD); 
  
        // Get the hashCode value 
        // using hashCode() value 
        System.out.println("HashCode value: "
                           + CLD.hashCode()); 
    } 
}

输出：

Linked Blocking Deque: [1, 2, 3, 4]
HashCode value: 2101973421
