I don't like copy pasting for no reason. What errors are you getting?


Are those different files? If not, all imports need to be at the top, public classes in their own self named file, etc...

Ouf... so many error
don't write hundred lines of code without testing them
do it 25 lines at a time and test it

Obviously:
- variable name cannot start by a number: 1itemCode
- lots of variables not declared: tName, tAge, tAddress....
- extra } where theire should not
- duplicated methods like public static void main()
