Answer:

It goes like:

public class Program

{

public static void main(String[] args)

{

int j=18;

int sum=0;

for (int i =1; i<7; i++)

{

sum=sum+(i*(j-2));

j=j-2;

}

System.out.println(sum);

}

Explanation:

<u>Variables used: </u>

j : controls the first number in product and decreases by 2 each time the loop runs.

sum: saves the values of addition as the loop runs.

{

}

Explanation:

Inside the action performed method, pass the strings in text box.
check if the value has been modified then do the relevant conversions inside the conditional statement.
When the user clears, it will not do to the inch conversion.
