Question 1

Suppose int i = 5, which of the following can be used as an index for array double[] t = new double[100]?
◦ (int)(Math.random() * 100))
◦ i + 10
◦ Math.random() * 100
◦ i + 6.5
◦ i

Question 2

Analyze the following code.

public class Test {
public static void main(String[] args) {

int[] x = new int[3];

System.out.println("x[0] is " + x[0]);

}
}

◦ The program runs fine and displays x[0] is 0.
◦ The program has a compile error because the size of the array wasn't specified when declaring the array.
◦ The program has a runtime error because the array elements are not initialized.
◦ The program has a runtime error because the array element x[0] is not defined.
