using PrintWriter and file classes in java

I am to Modify the source code to write output to a user specified file rather than the console/keyboard. I am unsure how to do this any help will be appreciated.

I am also getting the following error...

Employee.java:65: reached end of file while parsing } ^ 1 error

----jGRASP wedge2: exit code for process is 1. ----jGRASP: operation complete.

Employee.java 
import java.io.IOException;
import java.io.InputStreamReader;
import java.io.BufferedReader;
import java.io.PrintWriter
import java.io.file;
class Employee
{
    private int id;
    private String name, designation;
    private float salary;

    public void getData() throws IOException
    {
        BufferedReader in = new BufferedReader(new InputStreamReader(System.in));
        System.out.println ("---Enter Employee Data---");
        System.out.print ("ID? ");
        id = Integer.parseInt(in.readLine());
        System.out.print("Name? ");
        name = in.readLine();
        System.out.print("Designation: ");
        designation = in.readLine();
        System.out.print("Salary: ");
        salary = Float.parseFloat(in.readLine());
        System.out.println("------------------------");
    }
    public void showData()
    {
        System.out.println("-------------------");
        System.out.println("ID: "+id);
        System.out.println("Name: "+name);
        System.out.println("Designation: "+designation);
        System.out.println("Salary: "+ salary);
    }
}
EmployeeRecords.java

        in = new BufferedReader(new InputStreamReader(System.in));

        System.out.print ("How many employees? : ");
        final int n;
        n = Integer.parseInt(in.readLine());

        Employee N[] = new Employee[n];
        for (int i=0; i<n; i++)
        {
            N[i] = new Employee();

            N[i].getData();
        }

        {
            N[i].showData();
        }
    }

here is the code again.. I don't know why it is not formatting correctly above.

Employee.java 
import java.io.IOException;
import java.io.InputStreamReader;
import java.io.BufferedReader;
import java.io.PrintWriter
import java.io.file;

{
    private int id;
    private String name, designation;
    private float salary;

    public void getData() throws IOException
    {
        BufferedReader in = new BufferedReader(new InputStreamReader(System.in));
        System.out.println ("---Enter Employee Data---");
        System.out.print ("ID? ");
        id = Integer.parseInt(in.readLine());
        System.out.print("Name? ");
        name = in.readLine();
        System.out.print("Designation: ");
        designation = in.readLine();
        System.out.print("Salary: ");
        salary = Float.parseFloat(in.readLine());
        System.out.println("------------------------");
    }
    public void showData()
    {
        System.out.println("-------------------");
        System.out.println("ID: "+id);
        System.out.println("Name: "+name);
        System.out.println("Designation: "+designation);
        System.out.println("Salary: "+ salary);
    }
}

        }

        {

    }
