Java program to design a class account using the inheritance and static that show all function of bank and generate account number dyanamically.

import java.util.*;
class Bank {
 static int acc_no = 10001;
 float amt;
 public void display() {
  System.out.println("Account no :" + acc_no);
  System.out.println("Current Amount :" + amt);
 }
 public bank() {
  amt = 1000;
  System.out.println("Ur account no is " + acc_no);
  acc_no++;
 }
 public void getamt() {
  System.out.println("Current balance :" + amt);
 }
 public void withdraw(float x) {
  if (amt == 1000 || amt <= x) {
   System.out.println("Sorry u can't withdraw");
  } else {
   amt = amt - x;
   System.out.println("amount withdrawn :" + x);
   System.out.println("After withdrawl");
   getamt();
  }
 }
 public void deposit(float x) {
  if (x == 0.0)
   System.out.println("OOPS 0 can't be deposited");
  else {
   amt += x;
   System.out.println("After deposition");
   getamt();
  }
 }
 public static void main(String args[]) {
  Scanner sc = new Scanner(System.in);
  bank b1 = new bank();
  b1.deposit(0);
  b1.withdraw(120.5 f);
  b1.display();
  System.out.println("\n");
  bank b2 = new bank();
  b2.deposit(1000.0 f);
  b2.withdraw(150.5 f);
 }
}
