Answer:

The problem in the following snippet is that the function "cost" returns the void and it cannot used as the expression in the print statement

Explanation:

public class Test

{

    public static void main(String[] args)

    {

          System.out.println(cost(10, 4));

     }

     public static void cost(int price, int reps)

     {

           for (int i = 0; i < reps; i++)  

           {

                   System.out.print(price);                

           }  

     }

}

Output:

Main.java:4: error: 'void' type not allowed here

        System.out.println(cost(10, 4));

                               ^

1 error

In the following code the void type is not allowed in the function "cost".

satela [25.4K]

Answer: To be useful for most household applications, DC voltage is passed through a step-down transformer.

Explanation: Voltage coming through AC or DC outlets is typically far too high for most household appliances to handle, so the current is passed through a step-down transformer to reduce the voltage to a usable level.

"The goal of this assignment is to give you some experience building a program that uses objects. You will use the BankAccount c
MArishka [77]

Answer:

see explaination

Explanation:

Please find my detailed implementation.

I have tested with Single Bank account object.

You can create array list of Bank Account in test program:

public class BankAccount {

private String name;

private int accountNumber;

private int PIN;

private double balance;

public BankAccount(int accN, int pin) {

accountNumber = accN;

PIN = pin;

}

public BankAccount () {

name = "Undefined";

accountNumber = 0;

PIN = 0;

balance = 0;

}

public String getName() {

return name;

}

public int getAccountNumber() {

return accountNumber;

}

public int getPIN() {

return PIN;

}

public double getBalance() {

return balance;

}

public void setName(String name) {

this.name = name;

}

public void setAccountNumber(int accountNumber) {

this.accountNumber = accountNumber;

}

public void setPIN(int pIN) {

PIN = pIN;

}

public void setBalance(double balance) {

this.balance = balance;

}

public void withdrawal(double amount) {

if(amount <= balance) {

balance = balance - amount;

}

}

public void deposit(double amount) {

balance += amount;

}

public void transferFunds (double amount, BankAccount toBankAccount) {

if(amount >= balance) {

toBankAccount.setBalance(amount + toBankAccount.getBalance());

balance -= amount;

}

}

atOverride //change the at with the at symbol

public String toString() {

return "{id:"+accountNumber+", name:"+name+", pin:"+PIN+", balance:$"+balance+"}";

}

}

#########

public class BankAccountTest {

public static void main(String[] args) {

BankAccount myAccount = new BankAccount(526323450, 1234);

myAccount.setName("Pravesh");

myAccount.setBalance(345.64);

System.out.println(myAccount);

BankAccount anotherAccount = new BankAccount(); //default constructor

System.out.println(anotherAccount);

}

}

CHALLENGE
Lorico [155]

Answer:

Following are the program to this question:

#include <stdio.h>//using the header file

int main()//main method

{

int y;//defining integer variable y

printf("Enter year value:");//print message

scanf("%d", &y);//use input method for input year value

if (y>= 2101)//defining if block that checks year greater then 2101

   printf("Distant future");//print message

else if (y>= 2001)//defining else if block that checks year greater then 2001

   printf("21st century"); //print message

else if (y>= 1901)//defining else if block that checks year greater then 1901

   printf("20th century");//print message

else  //defining else block

   printf("Long ago");//print message

   return 0;

}

Output:

Enter year value:1998

20th century

Explanation:

In the given C language code, inside the main method, an integer variable "y" is defined, which allows the user to input the year value, and use the multiple conditions to check the given value and print message when the condition is matched.  

  • Inside the "if" condition block, it checks the "y" variable value is greater and equal to 2101. so, it will print "Distant future", otherwise go to the next condition.
  • In this, if "y" value is greater than equal to "2001", it will print the message "21st century", otherwise go to the next condition.  
  • In this, If the value of "y" is greater than equal to "1901", it will print the message "20th century", and if all the above condition is not true, then it will go to the else block, and it will print "Long ago" as the message.
