Account.Java:

package accounts;

public class account {
    private int acno;
    private String name;
    private float balance;
    public void init() {
        acno = 0;
        name = "";
        balance = 0;
    }

    public int getAcno() {
        return acno;
    }

    public String getName() {
        return name;
    }

    public float RBalance() {
        return balance;
    }

    public void setAcno(int acno) {
        this.acno = acno;
    }

    public void setName(String name) {
        this.name = name;
    }

    public void setBalance(float balance) {
        this.balance = balance;
    }

    public void show() {
        System.out.println(String.format("Account number : %d", getAcno()));
        System.out.println("Name : " + getName());
        System.out.println("Balance : "  + balance);
    }
    public void deposit(int amt){
        balance += amt;
    }
    public void withdraw(int amt) {
        if (amt > balance)
            System.out.println("Not enough balance in account.");
        else balance -= amt;
    }

}

Account_data.Java

package accounts;

import java.util.Scanner;

public class Account_data {

    public static void main(String[] args) {
        Scanner input = new Scanner(System.in);
        account a = new account();
        System.out.println("Enter account number: ");
        int acc_no = input.nextInt();
        System.out.println("Enter name: ");
        String name = input.next();
        System.out.println("Enter balance :");
        float bal = input.nextFloat();
        a.setAcno(acc_no);
        a.setName(name);
        a.setBalance(bal);

        while (true) {
            System.out.println("MENU");
            System.out.println("Press 1 to deposit");
            System.out.println("Press 2 to withdraw");
            System.out.println("Press 3 to view details");
            System.out.println("Press 4 to view balance");
            System.out.println("Press 5 to exit");
            System.out.println("Enter choice: ");
            int choice = input.nextInt();
            switch (choice) {
                case 1:
                    System.out.println("Emter amount to deposit: ");
                    int amt = input.nextInt();
                    a.deposit(amt);
                    break;
                case 2:
                    System.out.println("Emter amount to withdraw: ");
                    int wamt = input.nextInt();
                    a.withdraw(wamt);
                    break;
                case 3:
                    a.show();
                    break;
                case 4:
                    System.out.println("Balance is : " + a.RBalance());
                    break;
                case 5:
                    System.exit(1);
                default:
                    System.out.println("Wrong choice");
            }
        }
    }
}
