Answer:

Auto-negotiation protocol is the modern technology in the networking. This protocol allow the ethernet equipment for automate different instillation steps. This type of protocol use by interconnecting various electronic devices for negotiating the speed of the link.

Advantages:

The auto negotiation protocol features used to maximize the throughput of data link layer.
This protocol are basically useful in the local area network (LAN), with multiple capability of connections.
The auto negotiation protocol extremely useful in twisted pair which are based on ethernet.

Disadvantages:

This type of protocol are not fixed data links and not used as backbone of the networks.
Duplex mismatch occur then, it cause significant loss in the packets.

Can you debug the following code using the given test code?public class SavingAccount{ // interest rate for all accounts private

Lyrx [107]

Answer:

Explanation:

The reason the code was not working was due to a couple of errors. First, the SavingAccount class needed to be public so that it can be accessed within the same file. Secondly, the savingsBalance variable was set to final and therefore could not be modified, the final keyword needed to be removed. Lastly, the constructor for the SavingAccount class was incorrect. Constructors do not use the keyword void and instance class variables need to be referenced using the this keyword.

class SavingAccount{

// interest rate for all accounts

private static double annualInterestRate = 0;

private double savingsBalance;

public SavingAccount(double savingsBalance) {

this.savingsBalance = savingsBalance;

}

public void calculateMonthlyInterest() {

savingsBalance += savingsBalance * ( annualInterestRate / 12.0 );

}// end method calculateMonthlyInterest

// modify interest rate

public static void modifyInterestRate( double newRate ) {

annualInterestRate = ( newRate >= 0 && newRate <= 1.0 ) ? newRate : 0.04;

} // end method modifyInterestRate

// get string representation of SavingAccount

public String toString() { return String.format( "$%.2f", savingsBalance );

} // end method toSavingAccountString

}// end class SavingAccount

// Using this test codepublic

class SavingAccountTest{

public static void main(String[] args) {

SavingAccount s1 = new SavingAccount(400);

SavingAccount s2 = new SavingAccount(1000);

SavingAccount.modifyInterestRate(0.05);

System.out.printf("SavingAccount 1 is: %s\nSavingAccount 2 is: %s", s1, s2);

s1.calculateMonthlyInterest(); s2.calculateMonthlyInterest();

System.out.printf("\nSavingAccount 1 after the interest is: %s\nSavingAccount 2 after the interest is: %s", s1, s2);

SavingAccount.modifyInterestRate(.025);

s1.calculateMonthlyInterest();

s2.calculateMonthlyInterest();

System.out.printf("\nSavingAccount 1 after the new interest is: %s\nSavingAccount 2 after the new interest is: %s", s1, s2); }}
