Hi Experts, if I have a java file that has a main method and executes on its own, what changes are needed to change it to a bean?

A java class cannot 'execute on its own' - if it's an application, it has to have its main method called. Turning it into a bean would really entail ensuring that it has an empty constructor and making sure it has private member variables with public accessor/mutator methods.

private int someVal;

public void setSomeVal(int someVal) {
      this.someVal = someVal;
}

public int getSomeVal() {
      return someVal;
}

So a bean can have a main method?

So if I have a java file declared like so:

import statements

public class sample {
  public static void main (String args[]) throws Exception {
 
  }
}

Do I need to make the changes you suggested?
