Hi

you can not declare a method as abstract static,to have a static method in your abstract class write like this.

public abstract class Factory {

    public static String get(...) {
     return null;
      }
    
    public static int save(...) {
        ...
    }
}

Now you can over ride this method in your MyFactory class.
Hope this will help you.

A cheap workaround if you really want the method to be static:

public abstract class Factory {

  public abstract String getXXX(int param);
    
  public static int save(...) {
        ...
  }
}

public class MyFactory extends Factory {
  public String getXXX(int param) {
    return getXXXStatic(param);
  }
  public static String getXXXStatic(int param) {
        ....
  }
    
}
