Illegal Character when trying to compile java code ,getting illegal character: '\u0000'

This error will occur if you have unwanted character other than UTF-8 in your jave file .

To resolve this open your file in notepad++

Select encoding type as mentioned in below image

Remove all these characters from file and save file.
Again Compile same file .This time you should get error while compiling file.
