Should I learn C++ first or Java?

It's not quite that simple, Mary. All programming languages exist for a reason; one isn't necessarily better than the other. It depends on what you want to do. Out of those two options, I'd recommend you to try Java, as it's easier to learn and there are courses for it here on Treehouse, while there are no courses in C++ here.

if you've ruled out webier languages like PHP, python or other options like c#, I'd suggest java. I think it's a pretty good general purpose language with decent options for different kinds of use (android, web use, stand alone apps etc.). I think it's easier than c++, but that might just be me. I struggled with C++'s use of pointers. (a less constructive answer might be that it depends what brand of masochist you are - C++ and java obviously have a reputation for being harder than a lot of newer web languages). You might want to clarify what you want to make as it might be a factor.

Neither. Go with Ruby or Python unless you have a strong reason for avoiding them, easier to learn and applicable everywhere. If there is no other choice, go with Java. There is a much higher chance you will struggle with C++
