Given N rectangles with edges parallel to axis, calculate the area of the union of all rectangles. The input and output are files specified in program arguments. Input is represented by N lines with 4 numbers separated by spaces, defining 2 opposite vertices of the rectangle. Output file shoul...
In the Main() function we create an instance of the "Rectangle" class with a width of 7 and a height of 12, and call its methods to calculate the area and perimeter. We then modify the width and height using the setter methods and print the updated rectangle area and perimeter. Sample...

Constructors are the methods having the same name as that of the class and are automatically executed on defining an object. The main purpose of a constructor is to initialize a new object. Java does not allocates memory for objects at application startu
