Console

Console — state the definition in one sentence. For Console, know the key keywords / API types involved.

Be ready with one tiny runnable Console example.

Mention one common Console mistake and the fix.

Write one tiny example for Console. Compile, print one result, and say the output out loud before you type.

Use Console only when the problem needs it. Don’t force it into every program. Know one beginner trap.

Let's take this on the board with one tiny Main class — no extra files. Output: Asha scored 72 then Pass. Real Main. Swap marks/name to show one idea from Console. Start from main, go line by line, and stop at each print. That output is the proof for Console.

Exam tip

Explain Console as: definition → why → one code idea.

Example

// Console
public class Main {
  public static void main(String[] args) {
    int marks = 72;
    String name = "Asha";
    System.out.println(name + " scored " + marks);
    if (marks >= 40) System.out.println("Pass");
  }
}

Output: Asha scored 72 then Pass. Real Main. Swap marks/name to show one idea from Console.

RememberFor Console, say the output before you code.
TrapConsole — only memorising the heading. No example, no trap.
