1Z0-829 Practice Question: Handling Date, Time, Text, Numeric and Boolean Values

Which code correctly reads a line of text from the console using System.console()?

⚠ Common exam trap

Many candidates choose option D because `BufferedReader` is a common pattern for reading input, but they overlook that the question explicitly requires `System.console()`, not just any reader of `System.in`.

Why each option matters

Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.

Correct answer & explanation

✓

Console cons = System.console(); String line = cons.readLine();

`System.console()` returns a `Console` object that provides a direct, secure method for reading text from the console without buffering issues. The `readLine()` method reads a line of text as a `String`, which is the intended approach when using the console API.

Console cons = System.console(); String line = cons.readLine();
Why this is correct
Correct: Console.readLine() reads a line of input from the console.
✗
DataInputStream dis = new DataInputStream(System.in); String line = dis.readLine();
Why it's wrong here
