When I try to run on a school computer I get a notification that says, "Unable To Launch."

Question

The notification says, "Unable To Launch. The selection cannot be launched, and there are no recent launches." Has this happened to anyone else? It wont let me run any of my projects.

Answer 1

Did you create a Java Project, rather than a generic "Project"?

Did you not put the .java files inside the "src" folder within your project?

Are you lacking a proper main method, with the correct syntax?

public static void main(String args[]) {
...
}
