Question 2
//ArrayProcessTest.java
public class ArrayProcessTest {
public static void main(String[] args) {
int[] arr = {0, 1, 2, 3, 4, 5, 6, 7, 8, 9};
String str = process(arr, 3, 8); // Line 5
System.out.println(str);
}
/*INSERT*/
}
Line 5 is giving a compilation error as the process method is not found. Which of the following method definitions, if used to replace /INSERT/, will resolve the compilation error?
-
A
private static String process(int[] arr, int start, int end) {
return null;
}
-
B
private static int process(int[] arr, int start, int end) {
return null;
}
-
C
private static String[] process(int[] arr, int start, int end) {
return null;
}
-
D
private static int[] process(int[] arr, int start, int end) {
return null;
}

Correct answer: A
Explanation
It is clear from Line 5 that the method name should be process, it should be a static method, it should accept 3 parameters (int[], int, int), and its return type must be String.
