Answer:

If we delete record number 15 in a primary table, but there's still a related table with the value of 15, we end up with an orphaned record. Here, the related table contains a foreign key value that doesn't exist in the primary key field of the primary table. This has resulted in an “orphaned record”.

Answer: float

Explanation:

This is asking what would the remainder be of 5/2. I am not totally sure what you are asking but float is used with remainders because it could have a decimal like 3.33 that would throw an error for anything other than float.

how do you call the squares method to compute the first five squares and store the result in an array numbers

IRINA_888 [86]

Answer:

The method can be called using:

int[] returnarray = Squares();

Where returnarray represents the name of the array

Explanation:

To answer this, I will make an assumption that the Square method is an int array method (i.e. it returns array).

So, to call the method from main, an array has to be declared to get the values:

int[] returnarray = Squares();

Then an iteration is created to iterate through the array in order to print the array elements.

for (int i = 0; i < returnarray.length; i++)

System.out.print(returnarray[i]+ " ");

-------------------------------------------------------------------------------------------

The answer ends here

-------------------------------------------------------------------------------------------

As an addition, the complete program that includes the method and the main is:

public class Main{

public static int [] Squares(){

int [] arr = new int[5];

for(int i = 1;i<6;i++){

arr[i-1] = i*i;

}

return arr;

}

public static void main(String[] args) {

int[] returnarray = Squares();

for (int i = 0; i < returnarray.length; i++)

System.out.print(returnarray[i]+ " ");

}

}
