peek() 和pop() 是Java 中 Stack 类提供的两个重要方法,用于操作栈顶元素。 peek() 方法: 功能:查看栈顶元素,但不从栈中移除它。 返回值:返回栈顶元素的值。 异常:如果栈为空,会抛出 EmptyStackException 异常。 示例代码: java Stack<Integer> stack = new Stack<>(); stack.push(1)...
原文:https://www.geeksforgeeks.org/stack-peek-method-in-c-sharp/ 该方法(属于系统。集合命名空间)用于返回堆栈顶部的对象,而不移除它。此方法类似于 Pop 方法,但 Peek 不会修改 Stack。语法:public virtual object Peek (); 返回值:返回栈顶的对象。异常:在空栈上调用 Peek()方法会抛出invalid operation...
Stack.peek（）和Stack.pop（）的区别 Stack.peek（）和Stack.pop（）的区别Stack.peek()peek()函数返回栈顶的元素，但不弹出该栈顶元素。Stack.pop()pop()函数返回栈顶的元素，并且将该栈顶元素出栈。

This method is similar to the Pop method, but Peek does not modify the Stack.null Nothing nullptr unit a null reference (Nothing in Visual Basic) can be pushed onto the Stack as a placeholder, if needed. To distinguish between a null value and the end of the stack, check the Count ...
