New to programming in general (JAVA). How should I fix these errors? Is the nested if-else structure correctly ordered?

I am working on a program using Java and I am getting errors. The purpose of the program is to code a while-loop with a nested if-else structure within an if-else structure. (1) There is an error on line 33 that says "variable age might not have been initialized" even though it is declared in the main()? (2) Am I correctly nesting the if-else structures inside the while? (3)Are the curly brackets correctly placed? Please let me know if I am doing anything wrong or could be doing anything better! Updated question
