Explanation / Answer

In 1 question you have so many problems,it will be difficult for me to provide running code for so many problems in single one question.

I am giving working code for 1 problem ,kindly ask different question fo other problems.Hope you unserstand it.

Solution to problem 1:-

import java.io.*;

import java.util.Scanner;

class studentDetails {

    public String name[][] = new String[10][10];

    void getDetails(int n)

     {

        Scanner get = new Scanner(System.in);

        int limit=n;

        System.out.println("Enter "+limit+" Student Details ");

        for(int i=0;i<limit;i++)

        {

            System.out.println("Enter Student #"+(i+1)+" Login_ID, Password & 2 subjects name:");

            for(int j=0;j<4;j++)

            {

                name[i][j] = get.nextLine();

            }

        }

         

        display(limit);

    }

    void display(int limit)

    {

        System.out.println("Student Lgin Id"+" "+"Password"+" "+"Subject1"+" "+"Subject2");

        for(int i=0;i<limit;i++)

        {

            for(int j=0;j<4;j++)

            {

                System.out.print(name[i][j]+" ");

            }

        System.out.println();

        }

    }

     

     

}

class collegeOffice {

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

    {  

        Scanner in = new Scanner(System.in);

        System.out.print("Enter Number of Students:");

        int n = in.nextInt();

        studentDetails std = new studentDetails();

        std.getDetails(n);

             

            PrintStream output = new PrintStream(new File("StudentDetails.txt"));

            output.println("Student Lgin Id"+" "+"Password"+" "+"Subject1"+" "+"Subject2");

            output.println("======================================");

            for(int i=0;i<n;i++)

            {

                for(int j=0;j<4;j++)

                {

                    output.print(std.name[i][j]+" ");

                }

            output.println();

            output.println("======================================");

            }

            output.close();

    }

}
