Answer:
If we delete record number 15 in a primary table, but there's still a related table with the value of 15, we end up with an orphaned record. Here, the related table contains a foreign key value that doesn't exist in the primary key field of the primary table. This has resulted in an “orphaned record”.
Answer:
//The Employee Class
public class Employee {
char name;
long ID;
//The constructor
public Employee(char name, long ID) {
this.name = name;
this.ID = ID;
}
//Method Get Person
public void getPerson (char newName, long newId){
this.ID = newName;
this.ID = newId;
}
//Method Print
public void print(){
System.out.println("The class attributes are: EmpName "+name+" EmpId "+ID);
}
}
The working of the class is shown below in another class EmployeeTest
Explanation:
public class EmployeeTest {
public static void main(String[] args) {
Employee employee1 = new Employee('a', 121);
Employee employee2 = new Employee('b', 122);
Employee employee3 = new Employee('c', 123);
employee1.print();
employee2.print();
employee3.print();
}
}
In the EmployeeTest class, Three objects of the Employee class are created.
The method print() is then called on each instance of the class.
Answer:
- import java.util.Scanner;
- public class MealPriceCalculation{
-
- public static void main(String[] args) {
-
- Scanner input = new Scanner(System.in);
- System.out.print("Enter meal price: ");
- double meal = input.nextDouble();
- System.out.print("Enter tip: ");
- double tip = input.nextDouble();
-
- calculatePrice(meal,tip);
- calculatePrice(meal,(int)tip);
-
- }
-
- public static void calculatePrice(double meal, double tip){
- System.out.println("Total meal price: $" + (meal + tip) );
- }
-
- public static void calculatePrice(double meal, int tip){
- System.out.println("Total meal price $" + (meal+tip));
- }
- }
Explanation:
The solution code is written in Java.
Overload methods are the methods that share the same name but with different method signature. In this question, we create two overload methods calculatePrice (Line 17-23). One version will accept parameter meal and tip in double type and another will accept parameter meal in double but tip in integer. Both of this method are doing the same job which is just printing the total of meal.
In the main program, create a Scanner object and use it to prompt user to input meal price and tip (Line 6-10). Next call the calculatePrice method for twice. In the first time, pass meal and tip as double type data to calculatePrice method (Line 12). In the second time, pass meal in double but tip in integer to the method. Only the method with parameter list that match the argument data type will be implemented and output the total meal price.
