Question
Analyze the following code:public class Test { public static void main(String[] args) { int[] x = new int[5]; int i; for (i = 0; i < x.length; i++) x[i] = i; System.out.println(x[i]); }}Group of answer choicesThe program displays 4.The program displays 0 1 2 3 4.The program has a compile error because i is not defined in the last statement in the main method.The program has a runtime error because the last statement in the main method causes ArrayIndexOutOfBoundsException.
Solution
The program has a runtime error because the last statement in the main method causes ArrayIndexOutOfBoundsException.
Here's why:
-
The code starts with the declaration of a class named Test.
-
Inside the Test class, there is a main method which is the entry point of any Java program.
-
Inside the main method, an integer array x of size 5 is declared and initialized. This means that the array can hold 5 integer values, and the index of these values will range from 0 to 4.
-
A for loop is used to assign values to the elements of the array x. The loop variable i starts from 0 and increments by 1 in each iteration until it reaches the length of the array (5). In each iteration, the value of i is assigned to the i-th element of the array.
-
After the for loop, the code tries to print the value of the i-th element of the array x. However, at this point, the value of i is 5 (because the for loop has finished executing), and trying to access the 5th index of the array x will cause an ArrayIndexOutOfBoundsException. This is because the valid indices of the array are from 0 to 4, and there is no element at the 5th index.
