Inner class file
Does anyone know if there is any way that a Java compiler ( or any IDE ) could have generated what appears to be an inner class file without that inner class having been defined in the original source code? For example, I have a program that has a .class file called Main$ForecastSales among its files. But there is no inner class defined inside the file Main.java, which is among the files. And when I run:
javap -c -l Main$ForecastSales
The output generated starts with:
"Compiled from "Main.java"
public class Main$ForecastSales extends java.lang.Object"
I could be wrong, but this suggests that there was an inner class called ForecastSales defined, at some point in the program's development, inside Main.java.
Does anyone have any other suggestions as to how the Main$ForecastSales.class file could have come to be in the program?
