Step 4: Code, Code, and Code Some More!

Java certifications are coding-heavy—you need strong hands-on skills.

Tips for Practice:

• Set up topic-wise folders in your IDE for organized practice.

• Experiment with exceptions, collections, and recursion.

• Solve mini-projects or problems on HackerRank/LeetCode.

Example:

public class ExceptionHandling {
    public static void main(String[] args) {
        try {
            int result = 10 / 0;
        } catch (ArithmeticException e) {
            System.out.println("Cannot divide by zero!");
        }
    }
}

Why This Helps: The more you code, the more naturally Java concepts will stick.
