I am coding a program for a movie trivia game that randomly shows a movie quote and the the user selects a movie name from a combo box that matches. I used a array for the movie quotes and a comboBox for the movie names. I have coded a portion of the program but I am stuck on how to compare the array quote being shown to what movie the user selects from the comboBox. I have tried numerous different things but none seem to work right. The way I have it coded now it shows that every movie I pick that it is right even if it is wrong. I am going to show part of the code here and also attach the entire solution for anyone that needs it .
