name=scan.nextLine();

This is a simple students database that counts the number of students print their names,marks ....etc
it's not finished yet but when i run the program (i use BlueJ) and when it comes to inputting the Student name
it ignores the line and go to the next input sentence (aka in this program student number

Output:
Enter No.ofStudents:
1
Enter Student Name:
Enter Student Number:
f

entered f to stop the loop, here's the code

Code :

---

import java.util.*;
 
public class StudentsDatabase
{
    public static void main(String[]args)
    {
        String name; 
        int nos,sn,subnum,marks,sum,avg,i,j;
        Scanner scan=new Scanner(System.in);
        sum=0; 
        i=0; //Student number Counter
        j=0;//Subject numbers
        nos=0;//number of students
 
 
        System.out.println("Enter No.ofStudents: "); nos=scan.nextInt();
        while(j<=nos)
        {
            j=j+1;
            System.out.println("Enter Student Name: "); name=scan.nextLine();
            System.out.println("Enter Student Number: "); sn=scan.nextInt();
            System.out.println("Enter Subject Number: ");subnum=scan.nextInt();
            System.out.println("S.no: "+sn+" S.name: "+name+" Sub.No: "+subnum);
              while (i<=subnum)
              {
                i=i+1;
                System.out.println("Enter Subject Mark: "); marks=scan.nextInt();
                System.out.println("M = "+marks);
              }
 
        }
 
    }
}

although i solved it in another way:

Code :

import javax.swing.*;
import java.util.*;
 
public class StudentsJdatabase
{
    public static void main(String[]args)
    {
        String name; 
        int n1,n2,n3,n4,sum,avg,i,j;
        Scanner scan=new Scanner(System.in);
        sum=0; 
        i=0; //Student number Counter
        j=0;//Subject numbers
        String nos,sn,subnum,marks;//number of students
 
        nos=JOptionPane.showInputDialog("Enter number of students"); n1=Integer.parseInt(nos);
        while(j<=n1)
        {
            j=j+1;
            name=JOptionPane.showInputDialog("Enter Student Name");
            sn=JOptionPane.showInputDialog("Enter Student Number");n2=Integer.parseInt(sn);
            subnum=JOptionPane.showInputDialog("Enter number of Subjects");n3=Integer.parseInt(subnum);
              while (i<=n3)
              {
                i=i+1;
                marks=JOptionPane.showInputDialog("Enter Mark");n4=Integer.parseInt(marks);
 
                sum=sum+n4;
              }
           avg=sum/n3;
 
           JOptionPane.showMessageDialog(null,"S.name: "+name+"  S.no: "+n2+"  Sub.No: "+n3+"   Average = "+avg, "Student Data",JOptionPane.PLAIN_MESSAGE);
 
        }
        System.exit(0);
    }
}

any idea on how to record the output in a table or something? (yeah i'm a noob)

what table do you want to record the output? u mean like you want to save it to a datasource so that the ur data will still be available after you have terminated your program? in that case u need a database like mysql or ms access and persist ur outputs on a table on that database.

just change the below line as shown below

System.out.println("Enter Student Name: "); name=scan.next();

that actually worked heh dunno why it didn't with the "nextLine" so if you don't type the Type of the variable it's left free or is it recording it as a String? anyways that isn't my concern now :)

as for recording it i meant if it could be shown in a table in the output but i guess that is still advanced to what i'm studying.

thanks alot thou, both of ya
