Java.util.Stack.get()方法用於從堆棧中獲取或檢索特定索引處的元素。
用法:
Stack.get(int index)
參數:此方法接受整數數據類型的強製參數索引。它指定要從堆棧中獲取的元素的位置或索引。
返回值:該方法返回存在於參數索引指定位置的元素。
以下示例程序旨在說明Java.util.Stack.get()方法:
程序1:
// Java code to illustrate get() method
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");
// Displaying the Stack
System.out.println("Stack: " + stack);
// Fetching the specific element from the Stack
System.out.println("The element is: "
+ stack.get(2));
}
}
輸出:
Stack: [Geeks, for, Geeks, 10, 20] The element is: Geeks
程序2:
// Java code to illustrate get() method
import java.util.Stack;
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("1");
stack.add("2");
stack.add("3");
stack.add("10");
stack.add("20");
// Displaying the Stack
System.out.println("Stack: "
+ stack);
// Fetching the specific element from the Stack
System.out.println("The element is: "
+ stack.get(4));
}
}
輸出:
Stack: [1, 2, 3, 10, 20] The element is: 20
