Example:
In the example below, the java.util.Stack.capacity() method is used to find out the current capacity of the stack.





import java.util.*;

public class MyClass {
  public static void main(String[] args) {
    //创建一个栈
    Stack<Integer> MyStack = new Stack<Integer>();

    //填充堆栈
    MyStack.push(10);
    MyStack.push(20);
    MyStack.push(30);
    MyStack.push(40);
    MyStack.push(50);

    System.out.println("Size of MyStack: " + MyStack.size()); 
    System.out.println("Capacity of MyStack: " + MyStack.capacity()); 
  }
}

上述代码的输出将是:

Size of MyStack: 5
Capacity of MyStack: 10
