Java OCA OCP Practice Question 1173

Question

A Java programmer has written the following method that takes an array of integers and sums up all the integers that are less than 100.

public class Main {
   public static void processArray(int[] values) {
      int sum = 0;
      int i = 0;//from  w ww  . j a  va2  s . com
      try {
         while (values[i] < 100) {
            sum = sum + values[i];
            i++;
         }
      } catch (Exception e) {
      }
      System.out.println("sum = " + sum);
   }

   public static void main(String args[]) {
      int[] a = { 1, 2, 3, 4, 5 };
      processArray(a);

   }
}

Which of the following are best practices to improve this code?

Select 2 options

A. Use ArrayIndexOutOfBoundsException for the catch argument.
B. Use ArrayIndexOutOfBoundsException for the catch argument and add code in the catch block to log or print the exception.
C. Add code in the catch block to handle the exception.
D. Use flow control to terminate the loop.

Correct Options are  : B D

Note

Empty catch blocks are a bad practice.

At run time, if the exception is thrown, the program will not show any sign of the exception.
