Java中的 Stack remove(int) 方法与示例
Java.util.Stack.remove( int index )方法用于从特定位置或索引的堆栈中删除元素。
句法:
Stack.remove(int index)
参数:此方法接受强制参数索引是整数数据类型,并指定要从堆栈中删除的元素的位置。
返回值:此方法返回刚刚从堆栈中删除的元素。
下面的程序说明了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 stack = new Stack();
// 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);
}
}
输出:
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 stack = new Stack();
// 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);
}
}
输出:
Stack: [10, 20, 30, 40, 50]
Removed element: 10
Final Stack: [20, 30, 40, 50]
