so the constuctor is saying ) expected, error not a statement and ; expected
Person num1, num2, num3;
num1=new Person(Allison, 6600 Crescent Ave, 32, 902
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.
