Answer 1

(A). Client program code

import java.io.*;
import java.util.Scanner;

class Loan {
   private String name, age, address, salary, loanAmount, loanType;
//constructor for variable initialization
   Loan(String n, String age, String address, String salary, String la, String lt) {
       this.name = n;
       this.age = age;
       this.address = address;
       this.salary = salary;
       this.loanAmount = la;
       this.loanType = lt;

   }
//function to store the data in the file
   public void createUser() {
       try {
           File fobj = new File("S:\\banking.txt"); /* creating the object of File class(Enter location according to your choice)*/
           fobj.createNewFile(); // creating file
           FileWriter myWriter = new FileWriter("S:\\banking.txt", true); /* creating FileWriter object to write in the file*/
           BufferedWriter out = new BufferedWriter(myWriter);
           out.write(this.name + " " + this.age + " " + this.address + " " + this.salary + " " + this.loanAmount + " " + this.loanType + "\n");
           out.close();
       } catch (IOException e) {
           System.out.println(e);
       }

   }

}

class Banking {
   public static void main(String[] args) {
       Scanner obj = new Scanner(System.in);
       System.out.println("Enter name");
       String name = obj.nextLine();
       System.out.println("Enter age");
       String age = obj.nextLine();
       System.out.println("Enter Loan type and choices are Housing, Vehicle, Personal");
       String loan_type = obj.nextLine();
       System.out.println("Enter Salary");
       String sal = obj.nextLine();
       System.out.println("Enter Loan Amount");
       String loan_amount = obj.nextLine();
       System.out.println("Enter address ");
       String add = obj.nextLine();
       Loan user = new Loan(name, age, add, sal, loan_amount, loan_type);//create object of class Loan
       user.createUser();//call function to store data in file
       System.out.println("Record added successfully");
       obj.close();

   }
}

OUTPUT:

(B). Manager program

import java.io.File; // File class
import java.io.FileNotFoundException; // class to handle errors
import java.util.Scanner; // Scanner class to read text files
public class Manager {
public static void main(String[] args) {
System.out.println(" NAme Age Address Salary Loan Amount Loan Type ");
try {
File obj = new File("S:\\banking.txt"); //creating the file object
Scanner sc = new Scanner(obj); //creating the object of scanner class to read file content
int i=1;
while (sc.hasNextLine()) { //Run while loop until the file has lines
String data = sc.nextLine();
System.out.println(i+". " + data); //printing the line of file
i++;
}
sc.close();
} catch (FileNotFoundException e) { // to catch exception
System.out.println("An error occurred.");
e.printStackTrace(); //print the stack of exception
}
}
}

OUTPUT:
