Could make it easier to use for java language?

[kesihai]

This extension is grate, but the file name is like D_Non_decreasing.java, every time I need to copy the file name to rename the class name then I could run the test, and need to change the class name to Main when submit the code.

Could you record a vedio how to use this extension in java language ?

Maybe the folder in below way could make it more firendly for java launuage.

problemA/Main.java

problemB/Main.java

problemC/Main.java
