Answer 1

The problem is at line 48. You should check if c == 1, not 2. This is because your for loop condition is i < j, so i will never reach j, it will max out at j - 1.
As a side note, your use of static vs. non-static methods doesn't really make sense to me. You should probably have all of them either non-static or static.

Answer 2

Thank you for your help. im fairly new to this and the java lesson mentioned that if a method or a variable has the same value for every instance then its better to declare them static. Hence i thought that print methods, setters and getters shall be static. correct me if I'm wrong and id appreciate of you could redirect me to a link or video
