You duplicated the type definition "Random randomGenerator". The type/variable definition only needs to be done once. More than that is an error for the compiler. After that the variable can be assigned or manipulated at will. Since you're initializing it immediately that is usually done all on one line.

Random randomGenerator = new Random();

Doing it on separate lines, you would just leave the type off of the assignment.

Random randomGenerator;
randomGenerator = new Random();
