即使有throws子句，也会出现未报告的异常

Question

我正在用Java语言编写简单的堆栈，但是在编译我的push方法时会导致错误“ java：未报告的异常StackOverflowException；必须被捕获或声明为抛出”。

我认为可以通过在方法中添加throws子句来解决此问题，但仍然出现错误。怎么了？

import java.util.ArrayList;

公共类堆栈{

// the maximum size of the stack
protected int stackSize;

// the internal structure of the stack
protected ArrayList<T> stack;

// the last popped element
protected T lastPoppedElement;

// the constructor
public Stack(int size) {
    stack = new ArrayList<>();
    stackSize = size;
}

public void push(T newElement) throws StackOverflowException {
    StackOverflowException e = new StackOverflowException();
    if(this.stackSize == this.stack.size()){
        throw e;
    }else{
        this.stack.add(newElement);
    }
}

public T pop() {
    try{
        this.lastPoppedElement = this.stack.get(this.stack.size() -1);
        return this.lastPoppedElement;
    }catch(IndexOutOfBoundsException e){
        System.out.println("The stack is empty.");
        T r = (T) this.lastPoppedElement;
        return r;
    }
}


public static void main( String[] args )
{
    Stack t = new Stack<>(5);
    t.push("hello");
    t.pop();
    System.out.println(t);
}

}
