Creating object instance

Question

I'm trying to create a new instance of an object using data supplied from a DataInputStream.
I can create a new instance of my object Nasjob using
Nasjob myjob = new Nasjob("12345","smith","K");
Using a DataInputStream I can obtain the string "12345","smith","K"
and assign it to a variable called MYPARAMS
When I try to substitute "12345","smith","K" with MYPARAMS
Eg
Nasjob myjob = new Nasjob(MYPARAMS);
I get a compilation error.
I'm new to java so any help greatly appreciated

Answer 1

So you have a construtor:
NasJob(String s1, String s2, String s3)
and you are calling it with
new NasJob(s)
Its not going to work:
You need to define a constructor:
NasJob(String s)
then do some tokenizing inside to get the three tokenized parameters in the string! The Java compiler is not clever enough to realise that the string you are passing to a constructor requiring three strings does infact contain three parameters seperated by commas!!
