Batch Processing

Batch Processing: state the definition in one sentence. For Batch Processing, know the key keywords / API types involved.

Be ready with one tiny runnable Batch Processing example.

Mention one common Batch Processing mistake and the fix.

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

Use Batch Processing 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 Batch Processing. Start from main, go line by line, and stop at each print. That output is the proof for Batch Processing.

Exam tip

Explain Batch Processing as: definition → why → one code idea.

Example

// Batch
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 Batch Processing.
