Unknown class file creation by Eclipse java

Question

Hi I am working on a java project. I am using eclipse as an IDE. I have a file FileProvider.java in the package com.ibm.wala.util.io. For this file Eclipse is making two class files FileProvider.class and FileProvider$EclipseUtil.class. Can someone tell me why Eclipse is creating second class file.

Answer 1

Because you defined an inner class called EclipseUtil in FileProvider.

Answer 2

You have an inner class called EclipseUtil in your FileProvider class.

Answer 3

As your FileProvider.java has declared EclipseUtil as inner class.
