Java Logic Mastery: Build FizzBuzz, Prime Detectors, and Palindrome Checks

Java remains a cornerstone of modern software development, powering everything from enterprise systems to Android apps. For beginners, the key to mastery isn't just reading theory—it's writing code that solves logical puzzles. This guide highlights three fundamental Java labs designed to sharpen your problem-solving skills and solidify your understanding of core syntax in just minutes.

Palindrome Number Check

Palindrome Number Check

Difficulty: Beginner | Time: 5 minutes

In this lab, you need to create a program that takes an integer input, finds the reverse of the input, and checks if the input is a palindrome number (i.e., the reverse of the input is equal to the original input).

Determining Prime Number Status

Determining Prime Number Status

Difficulty: Beginner | Time: 5 minutes

In this lab, your task is to create a program that takes an integer input, checks whether the number is prime or not, and prints either 'Prime Number' or 'Not a Prime Number' based on the divisibility of the number.

FizzBuzz Program: User Input Explanation

FizzBuzz Program: User Input Explanation

Difficulty: Beginner | Time: 5 minutes

In this lab, we will create a program that takes an integer input from the user and prints Fizz, Buzz, or FizzBuzz based on whether the number is a multiple of 3, 5, or both, respectively, or else prints the original number.
