Your problem is not on the "int" type but on the "insert" parameter to your array!


You gave there insert(String, String, String, String , int) but your class has constructor supports only (String, String, String, int, int)... So the last "String" argument on your insert should be without quotes (an "int" value).





Edit:





for example:


arr.insert("Web_Publishing", "Audrey_Cynthia", "Surg", "193", 2001);





should be





arr.insert("Web_Publishing", "Audrey_Cynthia", "Surg", 193, 2001);


this is according to the definition of your insert method. I hope you see the diference between the 2 examples.
