Question

Q19 Consider the following main function: 10 Points public class Main { public static void main(String[] args) { Office office = new Office("5421 Sennott Square"); office.setOccupant("Luis"); office.width 5.0; office.setDepth(4.0); office.closeDoor(); System.out.println( office.toString() ); هه فه Program output (ignore the colors, gradescope's fault): Office information: Location: 5421 Sennott Square Occupant: Luis Area: 20.0 Door: Closed Q19.1 Implement the class Office that makes the program above work and produce the correct output 10 Points public class Office { Enter your answer here

Answer 1

Greetings !

Note: 1. in a single java file we can have multiple classes but only one of them can be public. so i have removed public keyword from class Office.

Note 2: copy the following source code and save it as a Main.java file, thereafter compile and run it in java editor.   

// Source Java Code

public class Main{
public static void main(String []args){
Office office = new Office("5421 sennott square");
office.setOccupant("luis");
office.width = 5.0;
office.setDepth(4.0);
office.closeDoor();
System.out.println(office.toString());
}
}

class Office{
// declare width variable as a type double, which is set by main method to 5.
double width;   
/* When we call the constructor Office(), we pass a parameter to the constructor ("5421 sennott square"),
which will set the value of Location to "5421 sennott square": */
Office(String Location)
{
System.out.println("office Information :"); // print office info
System.out.println("Location: "+ Location); // print location
}

/* When we call the method setOccupant(), we pass a parameter to the method ("luis"),
which will set the value of Occupant to "luis": */
void setOccupant(String Occupant)
{
System.out.println("Occupant: "+ Occupant); //print Occupant
}

/* When we call the method setDepth(), we pass a parameter to the method (4.0), which will set the value of depth to 5,
also we print a area of office by multiplying width to depth */
void setDepth(Double depth)
{
System.out.println("Area: "+ width*depth); // it will print 5*4=20
}
  
//this method simply prints "door: closed"
void closeDoor()
{   
System.out.println("Door: Closed");
}
  
//overriding toString() method, otherwise it will print the hashCode of the object
public String toString(){
return "";
}
}

//Screenshot of the source java code
