Type: Bug

In VS Code, when I update my Java code or even comment out the entire code block, the output still shows the result from a previous run. It seems like VS Code is using a cached or outdated .class file instead of recompiling the latest changes.

---

Example:
Initial code:

public class Hello {
    public static void main(String[] args) {
        System.out.println("Hello");
    }
}

Output:
Hello

Then I updated the code:

public class Hello {
    public static void main(String[] args) {
        System.out.println("Hello");
        System.out.println("Hii");
    }
}

Expected Output:

Hello
Hii

Actual Output:
Hello

Then I even tried this (commented out everything):

// public class Hello {
//     public static void main(String[] args) {
//         // No code here
//     }
// }

Still, the output was:
Hello

What I’ve Tried:

• Saved the file before running (Ctrl+S)
• Deleted all .class files manually
• Recompiled manually using javac Hello.java
• Ran manually using java Hello
• Tried in both VS Code terminal and external terminal
• Restarted VS Code
• Disabled Code Runner extension (if installed)
• Ensured file name (Hello.java) matches class name (Hello)

---

Expected Behavior:
When I change the code or comment it out, the output should reflect the current version of the code. It should not show any output from previous versions.
Let me know if you'd like me to auto-generate the system info section based on your actual Java and VS Code setup. I can guide you through collecting that info too.
