Question

Write a main program in a class called SquareMain.java that instantiates two square objects called s1 and s2.

Perform the following actions on s1 and s2 using methods of the Square class

Create s1 using the default constructor

Create s2 using the regular constructor with side = 4;

Calculate the area of s2 and print its value as follows:

"The area of square s2 is v" where v is value returned by the area method

Print the result of comparing s1 and s2 using the isSame method. This would print true if they are the same, print false otherwise

Change the size of square s1 to 6.

Print both squares using the toString method of the Square class

Answer 1

class Square

{

protected int side;

public Square () { side=0; }

public Square(int s) { side =s; }

public int getSide() { return(side); }

public void setSide(int s) { side=s; }

public double getArea() { return(side*side); }

public boolean isSame(Square other) { return(other.side==this.side); }

public double getPerimeter() { return(4*side); }

@Override public String toString()

{

return(

new String(

"Square of side length " + side

)

);

}

}

/*************************************************/

class SquareMain

{

public static void main(String args[])

{

Square s1 = new Square();

Square s2 = new Square(4);

System.out.println(" The area of square s2 is " + s2.getArea());

System.out.println(" Square 1 is the same as square 2: "+

s1.isSame(s2));

s1.setSide(6);

System.out.println(" Square s1 " + s1.toString() + " and has area " + s1.getArea() + " and perimeter " + s1.getPerimeter());

System.out.println(" Square s2 " + s2.toString() + " and has area " + s2.getArea() + " and perimeter " + s2.getPerimeter());

}
