your panel class don t have a constructor that accepts a string  try change  RLS strid panel p   new RLS strid panel namn1     to  RLS strid panel p   new RLS strid panel    p setName1 name1

To understand get and set  it s all related to how variables are passed between different classes    The get method is used to obtain or retrieve a particular variable value from a class    A set value is used to store the variables   The whole point of the get and set is to retrieve and store the data values accordingly   What I did in this old project was I had a User class with my get and set methods that I used in my Server class   The User class s get set methods   public int getuserID                   getting the userID variable instance         return userID            public String getfirstName                   getting the firstName variable instance         return firstName            public String getlastName                   getting the lastName variable instance         return lastName            public int getage                   getting the age variable instance         return age             public void setuserID int userID                  setting the userID variable value         this userID   userID            public void setfirstName String firstName                  setting the firstName variable text         this firstName   firstName            public void setlastName String lastName                  setting the lastName variable text         this lastName   lastName            public void setage int age                  setting the age variable value         this age   age            Then this was implemented in the run   method in my Server class as follows     creates user object                 User use   new User userID  firstName  lastName  age                     Mutator methods to set user objects                 use setuserID userID                   use setlastName lastName                   use setfirstName firstName                                  use setage age
