Question
What 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); }}OptionsCompiler Error30Garbage value0
Solution
The output of the program will be a Compiler Error. In Java, a final variable can only be assigned once. Here, the variable 'i' is declared as final and is assigned a value twice, which is not allowed. Hence, it will throw a compiler error.
