Question

Consider the Rectangle2 java class definition below. Write the definition of an equals) method that checks if two Rectangle objects have the same dimensions Write a Java program to test the equals method public class Rectangle2 K private int width, length; public Rectangle2(int w, int 1) { setWidth(w); setLength(1); System.out.println("Inside parameterized!!!"); } public void setWidth(int w) { width = w;} public void setLength(int i) { length = 1;} int getWidth() { return width; } int getLength() { return length; } public void printInfo() { System.out.print("This is a + width); System.out.println("x" + length + " rectangle."); } 31 Selected Answer: public class TestRactangle2 {

Answer 1

class Rectangl2{
private int width,length;

public Rectangl2(int aWidth, int aLength) {
super();
width = aWidth;
length = aLength;
System.out.println("Inside parameterized!!!");
}

public int getWidth() {
return width;
}

public int getLength() {
return length;
}

public void setWidth(int aWidth) {
width = aWidth;
}

public void setLength(int aLength) {
length = aLength;
}

public void printInfo() {
System.out.print("This is a "+width);
System.out.println("x"+length+" rectangle.");
}

public boolean equals(Object obj) {
if (this == obj)
return true;
if (obj == null)
return false;
Rectangl2 other = (Rectangl2) obj;
if (length != other.length)
return false;
if (width != other.width)
return false;
return true;
}
  
}

public class TestRectangle {
public static void main(String[] args) {
Rectangl2 r1 = new Rectangl2(10, 20);
Rectangl2 r2 = new Rectangl2(10, 20);
r1.printInfo();
r2.printInfo();
System.out.println("equal? "+r1.equals(r2));
