first=firstName;
last=lastName;
homeadd=homeAddress;
homeph=homePhone;
cellnum=cellNumber;
}
public void printMenu(){

System.out.println("6. Terminate the program.");
int answer = sc.nextInt();
//Switch to navigate menu
switch (answer){
case 1: getaddress();
printMenu();
break;
case 2: //make method to search then print yes/no
break;
case 3: print(); //make a method to print

printMenu();
}
}

double contacts[];
//Get address
public void getaddress(){
