Question 3 1 pts What is wrong with the code below? class Apple { int diameter; public static void main(String[] args) { Apple app = new Apple(); app.test(); public void test() { int localVar; System.out.println("Local variable localVar is: " + localVar); System.out.println("Diameter is: " + diameter); O localVar is not initialized There is no no-argument constructor defined for the Apple class The test() method needs a 'return' keyword diameter is not initialized
