Write a public static method named evens that takes in 1 argument int a, and returns a String containing all positive even numbers with each separated by a comma from O up to that number inclusive if it is also even Remember if the argument is odd not to include it in the output
Remember there should be no trailing comma after the values
If the argument a is negative return a String that says "NONE!
(Do not print the String)
Example evens(5) String returned by method. 0.2.4
Example evens(8) String returned by method. 0.2.4,6,8
Example evens (9) String returned by method 0.246,8
Example evens(-5), String returned by method: NONE
Example evens(O) String retumed by method 0
Example evens(1) String returned by method 0

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."
