Ex 7: Write a program in Java with class Rectangle with the data fields width, length, area and colour. The length, width and area are of double type and colour is of string type .The methods are set_ length () , set_width (), set_ colour(), and find_ area ().

import java.io.*;
class rect
{
int width,length;
String color;
void set_length(int a)
{ length=a; }
void set_width(int a)
{ width=a; }
void set_color(String a)
{ color=a; }
int area()
{ return(width*length); }
String getcolor()
{ return(color); }
}
class s03_01
{
public static void main(String arg[])throws Exception
{
String s=null;
DataInputStream in=new DataInputStream(System.in);
rect a=new rect();
System.out.println("Enter the length for first rectangle");
s=in.readLine();
a.set_length(Integer.parseInt(s));
System.out.println("Enter the width for first rectangle");
s=in.readLine();
a.set_width(Integer.parseInt(s));
System.out.println("Enter the Color for first rectangle");
a.set_color(in.readLine());
rect b=new rect();
System.out.println("Enter the length for second rectangle");
s=in.readLine();
b.set_length(Integer.parseInt(s));
System.out.println("Enter the width for second rectangle");
s=in.readLine();
b.set_width(Integer.parseInt(s));
System.out.println("Enter the Color for second rectangle");
b.set_color(in.readLine());
if(a.area()==b.area() && a.getcolor().equals(b.getcolor()))
System.out.println("Matching Rectangle ");
else
System.out.println("Non Matching Rectangle ");
}
