Hello, I really need some help on some Java programming homework that is due tonight&tomorrow. Here is the homework (3 problems):

1) (Displaying a Square of Asterisks) Write a method squareOfAsterisks that displays a solid square (the same number of rows and columns) of asterisks whose side is specified in integer parameter

side. For example, if side is 4, the method should display

****

****

****

=========

2) (Circle Area) Write an application that prompts the user for the radius of a circle and uses a method called circleArea to calculate the area of the circle.

=========

3) (Hypotenuse Calculations) Define a method hypotenuse that calculates the hypotenuse of

a right triangle when the lengths of the other two sides are given. The method should take two arguments of type double and return the hypotenuse as a double. Incorporate this method into an application that reads values for side1 and side2 and performs the calculation with the hypotenuse method. Use Math methods pow and sqrt to determine the length of the hypotenuse for each of the

triangles in Fig. 6.15. [Note: Class Math also provides method hypot to perform this calculation.]
