Prepare to dive into a world of encapsulation, inheritance, and polymorphism as you tackle the intriguing "Bank Account Program" challenge. 💰 Delve into the realm of Java Web development by displaying a proverb on a web page using JSP. 🌐 Sharpen your mathematical abilities by calculating the area of a circle with precision. 🔢
Venture into the world of data structures as you store information using a TreeSet collection. 🌳 Embark on a thrilling journey of searching for elements in a two-dimensional array with a specific pattern. 🔍 Implement a "Stock" class to track the rise and fall of stock values. 📈 Finally, put your flow control skills to the test by solving a variety of programming challenges, including finding prime numbers, determining the greatest common divisor, and identifying Narcissistic numbers. 🧠
Dive into these captivating Java programming challenges and elevate your coding skills to new heights. Let's get started! 💻
1. Bank Account Program
In this challenge, you will simulate different operations of bank accounts. You will create a bank account class that encapsulates the attributes and methods of the class, and then create two subclasses - a savings account class and a credit account class. The savings account class will have an additional annual interest rate property and will perform the calculation of interest and deposit it into the account. The credit account class will have additional properties of overdraft limit and cash withdrawal limit and will override the withdrawal behavior of the parent class. This challenge will test your understanding of encapsulation, inheritance, and polymorphism. 🏦
2. Displaying Proverb on Web Page with JSP (Challenge)
In this challenge, you will learn about Java Web. The Java Web project and the Tomcat plugin are already provided. The task is to write code in the index.jsp file to display the provided proverb. 💻
3. Calculating the Area of a Circle
In this lab, you need to create a program that computes the area of a circle using a given radius by implementing a method that accepts the radius and pi as parameters and returns the computed area using the formula Area = 3.14 × radius × radius, and then prints the result. 🔢
4. Storing Data Information Using TreeSet
In this challenge, we will be storing data information using a TreeSet collection. The objective is to add a set of data to the TreeSet using the add() method and then print the collection object. The challenge requires using a specific set of data, so make sure to follow the provided instructions accurately. 🌳
5. Searching in a Two-Dimensional Array
In this challenge, we will work on a program that searches for an element in a two-dimensional array. The array has a specific pattern, where each row is sorted in ascending order from left to right, and each column is sorted in ascending order from top to bottom. Your task is to write a program that takes an integer input and determines whether the array contains that integer. You need to follow the provided sample code and use the hints given to perform the search efficiently. 🔍
6. Implement a Stock class
In this challenge, we will create a Java class named 'Stock' to accurately represent and track the rise and fall of a stock. The class will have specific data fields such as stock code, stock name, and previous and current stock values. We will also implement a method to calculate and retrieve the percentage change in the stock value. Finally, we will write a test class to validate the implementation of the Stock class by creating an instance of it and displaying the percentage change in value. 📈
7. Flow Control Statements for Multiple Requirements
In this challenge, we will be working on implementing flow control statements to address multiple requirements. The tasks include finding prime numbers, determining the greatest common divisor, identifying Narcissistic numbers, and calculating the sum of odd numbers. These tasks will test your understanding of data types, operators, flow control, and looping statements. 🧠
Embark on these captivating Java programming challenges and elevate your coding skills to new heights. Happy coding! 🚀
