Of course(if I understood your question correctly..).

Let's take your existing code and add the necessary parameters. Original code:

Code:

 public class Customer {
    
    String firstName, lastName, title, email, mobile;
    
    public Customer(){
        this.firstName = "firstName";
        this.lastName = "lastName";
        this.title = "title";
        this.email = "email";
        this.mobile = "mobile";        
       
    }
 }

and turn it into:

Code:

 public class Customer {
    // five-param constructor for a Customer 
    public Customer(
      String firstName, String lastName, String title, String email, String mobile){
        this.firstName = firstName;  // notice the removal
        this.lastName = lastName;    //  of the quotations " "
        this.title = title;
        this.email = email;
        this.mobile = mobile;        
    }
       
    }
  }

And now to instantiate your class:

Code:

  ...
  Customer c = new Customer("John", "Smith", "Developer", "foo@bar.com", "555-5555");
  ...

For more on this see Sun's tutorial on constructors.

There's many ways to perform both the creation and instantiation of a class. I hope I answered your question correctly.
