Image overlay and comparison code error.

[UniDue]

I am still very much a beginner in programming, and i am facing an issue with a code that i am hoping someone could help me with. I found the java code below for overlaying and comparing the pixels of two images in an online forum. When i try to compile the code i get a syntax error. Hope you can help me find the error. Here is the link to three images showing the errors that i am getting ( https://postimg.cc/gallery/fJZW2k5 ). Thanks in advance.
