Dry run the below programs and explain the reasons of output. If there is any error then correct that error with reasoning. class access { public int x; static int y; void cal(int a, int b) { x += a ; y += b; } } class static_specifier { public static void main(String args[]) { access obj1 = new access(); access obj2 = new access(); obj1.x = 0; obj1.y = 0; obj1.cal(1, 2); obj2.x = 0; obj2.cal(2, 3); System.out.println(obj1.x + " " + obj2.y); } }

Note: It`s python coding 1. Class Implementationa) Implement a class Rectangle with two attributes, width and height.b) Implement an init method with an optional parameter type. Set the default value of the attributes of width and height to 1.c) Implement a display method to print the values of width and height.d) Instantiate two objects of type rectangle, one with arguments one without. r1 = Rectangle(4, 5) r2 = Rectangle()e) Call display() to print width and height.Example OutputWidth: 4Height: 5Width: 1Height: 1

JAVACreate a class called Quadratic for representing a one-variable quadratic expression of the form: ax2 + bx + c a,b and c here are the coefficients.   The class should contain the following methods: * A constructor that accepts values for a, b, and c. * public double getA() * public double getB() * public double getC()   * public double evaluate (int x)   * will return the value of the expression at point x * public double discriminant() - that will return  (b2 - 4ac) * public boolean isImaginaryRoots() - roots are imaginary if (b2 - 4ac) < 0 * public boolean isRealRoots() - roots are real if (b2 - 4ac) >= 0 // these methods can only be invoked if the roots are not imaginary * public float firstRoot() * public float secondRoot() * public boolean isPerfectSquare(); // If the first and second roots are equal * Try to override the toString methods   * Write a sample main program that will work as shown below. Example output:   coefficient a: 4 coefficient b: 4 coefficient c: 1…
