}

public String getAccountNumber() {
return currentAccount.getAccountNumber();
}

public String getAccountHoldersName() {
return currentAccount.getAccountName();
}

}

Explanation / Answer

The command to be used to terminate the program is System.exit();

The method checkCreadentials is to be called in a loop from the main() method. Objects of account class have to be created in the main() method.

A counter integer variable has to be created and incremented every time Account.checkCreadentials returns check as false. The counter variable is initialised to 0.

The psuedocode is as follows:

class A1 {

public static void main(string args[]) {

account Account = new account();

boolean c = false;

int counter = 0;

while(!c) { //Loop runs till check returned by checkCreadentials() //becomes true

c = Account.checkCreadentials(abc, 123); //c is the value of check returned by checkCreadentials()

if(c==false)

counter++; //counter is incremented whenever c is false because of //wrong password entered

if(counter==3)   

System.exit(0); //Program exits as soon as value of counter becomes 3

}

}

}

Note: It is a Java convention that class name should start with a Capital letter. (Class name given here is account)
