My Stack Implementation In Java

Here we are going to design a full-featured class for Stack's Data structure.

• public MyStack(int size): Create a new stack with a given size
• public boolean push(int value): Push an element to the top of the stack and return true.
• public int pop(): Pop an element from the top of the stack and return the value.
• public int peek(): Peek the top value of the stack and return the value.
• public boolean isEmpty(): Return true if the stack is empty.
• public boolean isFull(): Return true if the stack is full.
• public int size(): Return the size of the stack.
• public boolean resize(int newSize): Resize the stack to a new size.
• public void printStack(): Print the stack.

public class HelloWorld {
    public static void main(String []args){
        System.out.println("Hello, World!");

        MyStack stack = new MyStack(5);
        stack.push(1);
        stack.push(2);
        stack.push(3);
        stack.push(4);
        stack.push(5);

        stack.printStack();

        System.out.println("Peek: " + stack.peek());
        System.out.println("Pop: " + stack.pop());
        System.out.println("Peek: " + stack.peek());

        stack.printStack();
    }
}
