Q) Develop a multithread application that allows to current withdrawals?

A)

class bankAccount

{

       int accno;

       float balance;

       bankAccount( int accno, float balance)

       {

              this.accno=accno;

              this.balance=balance;

       }

       void setbalance(float balance)

       {

              this.balance=balance;

       }

       float getbalance()

       {

              return this.balance;

       }

       void withdraw(float amount)

       {

              System.out.println("trying to withdraw RS:"+amount +"from A/C"+accno);

              System.out.println("try to get the balance info from A/c"+accno);

              for(int i=1;i<20;i++)

                     System.out.println(i);

              float bal=getbalance();

              System.out.println("balance in the A/c"+accno+"is Rs."+bal);

              if(bal>amount)

              {

                     bal=bal-amount;

                     setbalance(bal);

                     System.out.println("please collect Rs: "+amount);

                     System.out.println("balance of A/c"+accno+"ipdate to Rs:"+bal);

              }

              else

              {

                     System.out.println("insufficient funds");

              }

       }

}

class accountthread extends Thread

{

       bankAccount acc;

       float amt;

       accountthread(bankAccount acc, float amt)

       {

              this.acc=acc;

              this.amt=amt;

       }

       public void run()

       {

              acc.withdraw(amt);

       }

}

classmultithreadbankingapplication {

       public static void main(String[] args) throws Exception {

              bankAccount a1= newbankAccount(1001,3000);

              bankAccount a2= newbankAccount(1002,9000);

              accountthread t1= newaccountthread(a1,3000);

              accountthread t2=newaccountthread(a2,5000);

              t1.start();

              t2.start();

              t1.join();

              t2.join();

              System.out.println("final balance in the 1st account Rs"+a1.getbalance());

              System.out.println("final balance in the 2nd account"+a2.getbalance());

       }
