Explanation / Answer

double [] array1 = new double [10];

It will allow valid subscripts in the range of 0 - 9 and also Creates an instance of an array of 10 double values and also array1 to be a reference to an array of double values.

D.So All the above statements are correct.

Data hiding, which means that critical data stored inside the object is protected from code outside the object, is accomplished in Java by:

B)using the private access specifier on the class fields.

becaue if we specify the method as private it cannot be inherited until it is in the same class so it means Data hiding.

A constructor has the same name as the class.

Answer: D

but it doesn't return void and have any access sprecifier.

16)

public class IntArray
{
public static void main(String[] args) {
int[] x = {120, 200, 016};
for (int i = 0; i < x.length; i++)
System.out.print(x[i] + " ");
}
}

output:
-----------
120 200 14

17)

final int SUB = 12;
int[] x = new int[SUB];
int y = 100;
for(int i = 0; i < SUB; i++)
{
x[i] = y;
y += 10;
}

output:
----------
180

Thanks have a great day.
