Question

Look at the following array definition:

int [] numbers = (1,3,5,7,9);

What does the following code segment display?

1. System.out.println(numbers [3]);

2. x = numbers [2] + numbers [4];
System.out.println(x);

3. x = ++ numbers [1];
System.out.println(x);

Answer 1

The code segment displays specific values from the array.

Step-by-step explanation:

1. The code segment System.out.println(numbers[3]); will display the value at index 3 in the array, which is 7. So, the output will be 7.

2. The code segment x = numbers[2] + numbers[4]; System.out.println(x); will add the values at index 2 and index 4 in the array (5 + 9), and assign the result to the variable x. So, the value of x will be 14, and the output will be 14.

3. The code segment x = ++numbers[1]; System.out.println(x); will increment the value at index 1 in the array (3), and assign the incremented value to the variable x. So, x will be 4, and the output will be 4.
