Hi there! How are you doing?
I am just starting to work on freelancer so I am working cheap to increase review number. I am a senior software developer and proficient in Java. During all my degree we worked with Java 8.0 using NetBeans, Eclipse, Intelij, etc..
You have to be careful to not mistake Refactor with Replace, the safe refactor option some IDE's have is really useful. I can check your code and find the problem easily and fast.
Let me know if you are interested.
