Question
e correct answerWhat is the output of the following Java program?class Main { public static void main(String args[]) { final int i; i = 20; i = 30; System.out.println(i); }}
Solution
The Java program will not compile. In Java, a final variable is a constant. Once a final variable has been assigned, it cannot be changed. In this program, the final variable i is assigned a value of 20, and then the program attempts to assign it a new value of 30. This will cause a compile-time error. Therefore, there is no output from this program because it fails to compile.
