Java Stack remove(int)用法及代碼示例

Java.util.Stack.remove(int index)方法用於從特定位置或索引中從Stack中刪除元素。

用法:

Stack.remove(int index)

參數：此方法接受整數數據類型的強製參數索引，並指定要從堆棧中刪除的元素的位置。

返回值：此方法返回剛剛從堆棧中刪除的元素。

以下示例程序旨在說明Java.util.Stack.remove(int index)方法：

示例1:

// Java code to illustrate remove() when position of 
// element is passed as parameter 
  
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 in the Stack 
        stack.add("Geeks"); 
        stack.add("for"); 
        stack.add("Geeks"); 
        stack.add("10"); 
        stack.add("20"); 
  
        // Output the Stack 
        System.out.println("Stack: " + stack); 
  
        // Remove the element using remove() 
        String rem_ele = stack.remove(4); 
  
        // Print the removed element 
        System.out.println("Removed element: "
                           + rem_ele); 
  
        // Print the final Stack 
        System.out.println("Final Stack: "
                           + stack); 
    } 
}

輸出：

Stack: [Geeks, for, Geeks, 10, 20]
Removed element: 20
Final Stack: [Geeks, for, Geeks, 10]

示例2:

// Java code to illustrate remove() when position of 
// element is passed as parameter 
  
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 in the Stack 
        stack.add(10); 
        stack.add(20); 
        stack.add(30); 
        stack.add(40); 
        stack.add(50); 
  
        // Output the Stack 
        System.out.println("Stack: " + stack); 
  
        // Remove the element using remove() 
        int rem_ele = stack.remove(0); 
  
        // Print the removed element 
        System.out.println("Removed element: "
                           + rem_ele); 
  
        // Print the final Stack 
        System.out.println("Final Stack: "
                           + stack); 
    } 
}

輸出：

Stack: [10, 20, 30, 40, 50]
Removed element: 10
Final Stack: [20, 30, 40, 50]
