Java Stack hashCode()用法及代码示例

Java中的Java.util.Stack.hashCode()方法用于获取此Stack的哈希码值。

用法:

Stack.hashCode()

参数：该方法不带任何参数。

返回值：该方法返回此Stack的哈希码值，该值是Integer类型。

以下示例程序旨在说明Java.util.Stack.hashCode()方法：

示例1:与字符串元素堆叠。

// Java code to illustrate hashCode() 
import java.util.*; 
  
public class StackDemo { 
    public static void main(String args[]) 
    { 
        // Creating an empty Stack 
        Stack<String> stack = new Stack<String>(); 
  
        // Use add() method to add elements into the Stack 
        stack.add("Welcome"); 
        stack.add("To"); 
        stack.add("Geeks"); 
        stack.add("4"); 
        stack.add("Geeks"); 
  
        // Displaying the Stack 
        System.out.println("Stack: " + stack); 
  
        // Displaying the hashCode value of Stack 
        System.out.println("The hashCode value is: "
                           + stack.hashCode()); 
    } 
}

输出：

Stack: [Welcome, To, Geeks, 4, Geeks]
The hashCode value is: -878886256

示例2:与整数元素堆叠。

// Java code to illustrate hashCode() 
import java.util.*; 
  
public class StackDemo { 
    public static void main(String args[]) 
    { 
        // Creating an empty Stack 
        Stack<Integer> stack = new Stack<Integer>(); 
  
        // Use add() method to add elements into the Stack 
        stack.add(10); 
        stack.add(20); 
        stack.add(30); 
        stack.add(40); 
        stack.add(50); 
  
        // Displaying the Stack 
        System.out.println("Stack: " + stack); 
  
        // Displaying the hashCode value of Stack 
        System.out.println("The hashCode value is: "
                           + stack.hashCode()); 
    } 
}

输出：

Stack: [10, 20, 30, 40, 50]
The hashCode value is: 38490301
