Answer:see explanation
Explanation:
Hello, the solution is the following:
in a file named Shelf.java :
public class Shelf{
int length;
int breadth;
int capacity;
boolean occupied;
Shelf(int length,int breadth, int capacity){
this.length = length;
this.breadth = breadth;
this.capacity = capacity;
this.occupied = false;
}
//set methods
public void setLength(int length){
this.length = length;
}
public void setBreadth(int breadth){
this.breadth = breadth;
}
public void setCapacity(int capacity){
this.capacity = capacity;
}
public void setOccupied(boolean occupied){
this.occupied = occupied;
}
//get methods
public int getLength(){
return this.length;
}
public int getBreadth(){
return this.breadth;
}
public int getCapacity(){
return this.capacity;
}
public boolean getOccupied(){
return this.occupied;
}
//tostring method
public String toString(){//overriding the toString() method
return "Shelf: \n"+" length: "+Integer.toString(this.length)+" breadth: "+Integer.toString(this.breadth)+" capacity: "+Integer.toString(this.capacity)+" occupied: "+Boolean.toString(this.occupied);
}
}
in another file named ShelfCheck.java
public class ShelfCheck {
public static void main(String[] args) {
Shelf s1=new Shelf(100,150,300);
Shelf s2=new Shelf(200,200,234);
Shelf s3=new Shelf(300,222,543);
Shelf s4=new Shelf(400,434,654);
System.out.println(s1);
System.out.println(s2);
System.out.println(s3);
System.out.println(s4);
s4.setLength(5);
System.out.println(s4);
s2.setBreadth(2);
System.out.println(s2);
s3.setCapacity(1);
System.out.println(s3);
s1.setOccupied(true);
System.out.println(s1);
}
}
OUTPUT:
Shelf:
length: 100 breadth: 150 capacity: 300 occupied: false
Shelf:
length: 200 breadth: 200 capacity: 234 occupied: false
Shelf:
length: 300 breadth: 222 capacity: 543 occupied: false
Shelf:
length: 400 breadth: 434 capacity: 654 occupied: false
Shelf:
length: 5 breadth: 434 capacity: 654 occupied: false
Shelf:
length: 200 breadth: 2 capacity: 234 occupied: false
Shelf:
length: 300 breadth: 222 capacity: 1 occupied: false
Shelf:
length: 100 breadth: 150 capacity: 300 occupied: true
