Write a script that inputs a telephone number as a string in the form (555)555-5555. The script should use String method split to extract the area code as a token, the first three digits of the phone number as a token and the last four digits of the phone number as a token. Display the area code in one text field and the seven-digit phone number in another text field.

I wanted to know if this code was right and if not what needs to be fixed?
public class Time
{
public static void main(String[] args)
{
int Time = 197;
int hours=3;
int minutes=17;
{
int hours =3;
int left = 17;
System.out.println("197 minutes is 3 hours and 17 minutes");
} // end class Time
}

I am having a hard time with questions 6a and 6b. 6a. I have to write a class that declares a variable named minutes, which holds minutes worked on a job, and assign a value. Display the value in hours and minutes; for example, 197 minutes becomes 3 hours and 17 minutes. Be sure to use a named consant where appropriate. 6b. Write an interactive version of the Time class that accepts the minutes worked from a user. How do I do these questions? I am very confused on how to do them. Needed basic code help.
