[mcnam4119]

this is my classes code(i call this in my main)

import java.io.*;
import java.util.*;
public class NameAgeDatabaseClass {

public NameAgeDatabaseClass() {
}


BufferedReader buff=new BufferedReader(new InputStreamReader(System.in));
public void menu()throws IOException
{
System.out.println("**********Student Database**********");
System.out.println("1. Add Student to Database");
System.out.println("2. Edit Student in Database");
System.out.println("3. Delete Student from Database");
System.out.println("4. View Student's in Database");
System.out.println("5. Exit Student Database");
System.out.println("Pick a Menu option");
int choose= Integer.parseInt (buff.readLine());
}

public void addStudent()throws IOException
{
FileWriter fwAdd=new FileWriter("C:\\Test.txt",false);
PrintWriter output=new PrintWriter(fwAdd);
System.out.println("Enter the name of the Student");
output.println(buff.readLine());
output.println("");
System.out.println("Enter the age of the Student");
output.println(Integer.parseInt (buff.readLine()));
output.println("");
output.close();
fwAdd.close();
}

public void viewStudent()throws IOException
{
File myFile=new File("C:\\Test.txt");
Scanner sf=new Scanner(myFile);
System.out.println("*-*-*-*Student Database*-*-*-*");
System.out.println("Name: Age: ");
while(sf.hasNext())
{
System.out.println(sf.nextLine());
}
sf.close();
}

public void editStudent()throws IOException
{

}

public void deleteStudent()throws IOException
{

}

switch(choose)
{
case 1: //add student
addStudent();
break;

case 2: //edit student
//editStudent();
break;

case 3: //view student database
viewStudent();
break;

case 4: //delete student
//deleteStudent();
break;
}


}

this is my main code

mport java.io.*;
import java.util.*;
public class NameAgeDatabase {

public static void main(String[] args)throws IOException {

NameAgeDatabaseClass student=new NameAgeDatabaseClass();
student.menu();







}
}

What i am having trouble with is the deleting and editing of records without the use of arrays, i can do it with arrays but without i am unsure. (I am also using file handling if you didnt pick it up alredy)

My switch function also doesnt work but i can do that myself its a simple fix
