Consider the program below:public class Test{ public static void main(String[] args) {Int[] a;a = new int[10];for(int i = 0; i < a. length; i++)a[i] = i + 2;int result = 0;for(inti = 0; i < a. length; i++)result += a[i];System. out. printf("Result is: %d%n", result); } }The output of this program is:a. 62b. 64c. 65d. 67

c. 65

Explanation:

The output is 65.

An array of length 10 is created first. Then, the first for-loop fill the array with different values; The array element now become: 2, 3, 4, 5, 6, 7, 8, 9, 10, 11. The array element are generated using the equation a[i] = i + 2; so when i is 0, 1, 2, 3, 4, 5, 6, 7, 8, 9. i must be less than the array length (10).

a[0] = 0 + 2 = 2

a[1] = 1 + 2 = 3

a[2] = 2 + 2 = 4

a[3] = 3 + 2 = 5

a[4] = 4 + 2 = 6

a[5] = 5 + 2 = 7

a[6] = 6 + 2 = 8

a[7] = 7 + 2 = 9

a[8] = 8 + 2 = 10

a[9] = 9 + 2 = 11

result variable is declared and initialized to 0.

The second for-loop goes through the array and add individual element to result.

yup its correct its: c) b b

electromagnetic shielding is the practice of reducing the electromagnetic field in a space by blocking the field with barriers made of conductive or magnetic materials. shielding is typically applied to enclosures to isolate electrical devices from their surroundings, and to cables to isolate wires from the environment through which the cable runs. electromagnetic shielding that blocks radio frequency electromagnetic radiation is also known as rf shielding.

the shielding can reduce the coupling of radio waves, electromagnetic fields and electrostatic fields. a conductive enclosure used to block electrostatic fields is also known as a faraday cage. the amount of reduction depends very much upon the material used, its thickness, the size of the shielded volume and the frequency of the fields of interest and the size, shape and orientation of apertures in a shield to an incident electromagnetic
