Java OCA OCP Practice Question 2405

Question

What is the output of the following code? 

public class Main { 
    public static void main(String args[]) { 
        int[] arr = new int[5]; 
        byte b = 4; 
        char c = 'c'; 
        long longVar = 10; 
        arr[0] = b; /*from  w w  w  .  j  ava2s.c o m*/
        arr[1] = c; 
        arr[3] = longVar; 
        System.out.println(arr[0] + arr[1] + arr[2] + arr[3]); 
    } 
}
  • a 4c010
  • b 4c10
  • c 113
  • d 103
  • e Compilation error


e

Note

The code in this question won't compile due to 

arr[3] = longVar;

The preceding line of code tries to assign a value of type long to a variable of type int.

Because Java doesn't support implicit narrowing conversions (for example, long to int in this case), the assignment fails.
