Answer:
The algorithm is as follows;
1. Start
2. Input TeddyBears
3. Input Hours
4. WagebyTeddy = 2 * TeddyBears
5. WagebyHour = 5 * Hours
6. If WagebyHour > WagebyTeddy then
6.1 Print WagebyHour
7. Else
7.1. Print WagebyTeddy
8. Stop
Explanation:
The following variables are used;
TeddyBears -> Number of teddy bears made
Hours -> Number of Hours worked
WagebyTeddy -> Wages for the number of teddy bears made
WagebyHour -> Wages for the number of hours worked
The algorithm starts by accepting input for the number of teddy bears and hours worked from the user on line 2 and line 3
The wages for the number of teddy bears made is calculated on line 4
The wages for the number of hours worked is calculated on line 5
Line 6 checks if wages for the number of hours is greated than wages for the number of bears made;
If yes, the calculated wages by hour is displayed
Otherwise
the calculated wages by teddy bears made is displayed
Answer:
FileOutputStream out = new FileOutputStream("ObjectData.dat");
ObjectOutputStream ostream = new ObjectOutputStream(out);
ostream.writeObject(r);
Explanation:
For object serialization, we can use the writeObject method of java.io.ObjectOutputStream class.
The complete code fragment is as follows:
import java.io.*;
class Demo{
public static void main(String args[]){
try{
r = <Reference to Object to be serialized> ;
FileOutputStream out = new FileOutputStream("ObjectData.dat");
ObjectOutputStream ostream = new ObjectOutputStream(out);
ostream.writeObject(r);
ostream.close();
} catch(Exception e){
e.printStackTrace();
}
}
}
Answer: B) Shape is a base class, and circle and square are derived classes of Shape.
Explanation:
Shape is a base class because circle and squares are the shapes so these are the derived class of the shape, which is inherited by the shape like circle and square. As, the base class (shape) is the class which are derived from the other classes like circle and square and it facilitates other class which can simplified the code re-usability that is inherited from the base class. Base class is also known as parent class and the super class.
