Question

When I try to compile this program, it highlights "int = sub;" and says "not a statement". I'm not entirely sure what I'm doing wrong. I'm sure it's a little stupid mistake, but I can't figure it out.

Also, I am new to working with the switch class and am unsure if I wrote the code right for that. Just wondering what is wrong about it if it is wrong.

System.out.println("The class you chose is: " +classString);

}
}

Explanation / Answer

"int" is a type declarator. It is a special keyword in Java. What you are doing in that line of code is trying to assign the value of "sub" to "int". Did you mean to say "int class= sub;"? It looks like you're using the "class" variable later on without declaring it, and it looks like on that line you're trying to declare a variable without giving the compiler the name of the variable. In short, I think you meant int class = sub;
