Assume the availability of an existing class, ICalculator, that models an integer arithmetic calculator and contains:an instance
Over [174]

Answer:

Explanation to the approach and code given below

Explanation:

I am considering that you need only a defined subclass and not the working program.

So given statement is,  

The class  ICalculator has one additional method ,sign, that receives no arguments , and doesn't modify currentValue. Instead, it simply returns 1, 0 or -1 depending on the whether currentValue is positive, zero, or negative respectively.

Here is the code:

public class ICalculator1 extends ICalculator {

       public int sign() {

         if (currentValue != 0) {

           return currentValue * -1;}

         else {

           return 0;  

           }

       }

   }

or you can try this alternative soluton.

public int sign() {

  int value = add(0);   // add 0 and return currentValue

  if (value > 0) return 1;

  else if (value < 0) return -1;

  else return 0;

}

What is the correct html element for inserting a line break?
Butoxors [25]
<br> or <br/>

The forward slash can be omitted and still function perfectly fine, unless you are working with XHTML (XML), then do include the forward slash.

It's your personal preference on which one you use, but be consistent! I personally prefer the latter.

The number of bytes in an array is always a multiple of the number of ____ in an array.
liq [111]

Answer:

The Correct answer for the given question is "elements " .

Explanation:

The number of bytes is always multiple by the number of array elements in an array to getting total memory occupy by any array .

For example :

int a[100];

Since in c language int is 2 bytes

So memory in number of bytes =2*100=200 bytes

Indexes is keep the track of physical location of any file this is also used to track the logical location of file in database so this option is wrong

Subscripts are the index number of an array so we will never used subscripts to getting total memory occupy by any array so this option is wrong

Iterators  are the loop so this option is wrong.

Due to this the correct answer is elements.
