Question

so the constuctor is saying ) expected, error not a statement and ; expected

    Person num1, num2, num3;

Answer 1

Step 1:

First you can check your Person class object is created.

Print some message in

 public Person() {
      System.out.println("in default constructor");
 }

if you can not see any print statement then problem with object.

Step 2:

Check what you pass and passed value is print or not.

If not print then problem with your parameter(argument).

Your Problem:

You are not passing actual string value,You have to pass string value wihin ""

num1=new Person("Allison", "6600 Crescent Ave", 32, 9024231421);

Many SO user give actually answer but this stuff is for feature reader so user can see and don't take mistake next time.

Answer 2

num1=new Person(Allison, 6600 Crescent Ave, 32, 9024231421);

should be

num1=new Person("Allison", "6600 Crescent Ave", 32, 9024231421);

String, String, int and long are expected in this order by your constructor, which is defined by public Person(String nm, String adr, int ag, long phn).

Allison without (double)quotes is not a String.

Answer 3

You are not passing a string for Name and Address to your constructor, try changing

num1=new Person(Allison, 6600 Crescent Ave, 32, 9024231421);

to

num1=new Person("Allison", "6600 Crescent Ave", 32, 9024231421);

Answer 4

Because strings are always used within the double quotes . put your arguments which are strings in the double quotes.

Answer 5

you are calling construtor that in not exist for your first argument you have defined string so pass in double quote while calling construtor
