            BufferedWriter bw = new BufferedWriter(fw);
            PrintWriter outFile = new PrintWriter(bw);
            for (int i = 0; i < 5; i++) {
                System.out.print("Enter Name : ");
                String name = stdin.readLine();
                outFile.println(name);
            }
            outFile.close();
        } catch (IOException e) {

📘 Explanation

🎯 How to learn from this example

First understand the algorithm carefully. Then study the program line-by-line and compare it with the output. Finally, review the explanation section to strengthen your logic and programming understanding.

🔥 Practice suggestion

Rewrite the program without looking at the code. Modify values, conditions or logic and run it again. This helps improve confidence and strengthens coding skills much faster.
