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
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).
