Java Stack remove(Object)用法及代码示例


Java.util.Stack.remove(Object o)方法用于从堆栈中删除任何特定元素。

用法:

Stack.remove(Object o)

参数:此方法接受对象类型为Stack的强制性参数,并指定要从Stack中删除的元素。


返回值:如果找到指定元素并将其从堆栈中删除,则返回True,否则返回False。

以下示例程序旨在说明Java.util.Stack.remove(Object o)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() 
        boolean res = stack.remove("20"); 
  
        // Print the removed element 
        System.out.println("Was 20 removed: "
                           + res); 
  
        // Print the final Stack 
        System.out.println("Final Stack: "
                           + stack); 
    } 
}
输出:
Stack: [Geeks, for, Geeks, 10, 20]
Was 20 removed: true
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() 
        boolean res = stack.remove("100"); 
  
        // Print the removed element 
        System.out.println("Was 100 removed: "
                           + res); 
  
        // Print the final Stack 
        System.out.println("Final Stack: "
                           + stack); 
    } 
}
输出:
Stack: [10, 20, 30, 40, 50]
Was 100 removed: false
Final Stack: [10, 20, 30, 40, 50]
