Write the definition of a class Counter containing: An instance variable named counter of type int. An instance variable named limit of type int. A static int variable named nCounters which is initialized to 0. A constructor taking two int parameters that assigns the first one to counter and the second one to limit. It also adds one to the static variable nCounters. A method named increment. It does not take parameters or return a value; if the instance variable counter is less than limit, increment just adds one to the instance variable counter. A method named decrement that also doesn't take parameters or return a value; if counter is greater than zero, it just subtracts one from the counter. A method named getValue that returns the value of the instance variable counter. A static method named getNCounters that returns the value of the static variable nCounters.

Write a program that displays the following menu: geometry calculator 1. calculate the area of a circle 2. calculate the area of a rectangle 3. calculate the area of a triangle 4. quit enter your choice (1-4): if the user enters 1, the program should ask for the radius of the circle and then display its area. use the following formula: area = ď€(the square of r) use 3.14159 for ď€ and the radius of the circle for r. if the user enters 2, the program should ask for the length and width of the rectangle and then display the rectangle’s area. use the following formula: area = length * width if the user enters 3, the program should ask for the length of the triangle’s base and its height, and then display its area. use the following formula: area = base * height * .5 if the user enters 4, the program should end. input validation: display an error message if the user enters a number outside the range of 1 through 4 when selecting an item from the menu. do not accept negative values for the circle’s radius, the rectangle’s length or width, or the triangle’s base or height. note: if the user enters an improper menu choice (1-4), the program prints "the valid choices are 1 through 4. run the program again and select one of those." if the user enters a negative radius, the program prints "the radius can not be less than zero." if the user enters a negative value for height or base, the program prints "only enter positive values for base and height."
