Design and implement two Java programs for programming exercise 6.19, page 238. The first program (called MyTriangle) is to implement the specified methods. The second program (called TestMyTriangle) is to test the first program methods. Program TestMyTriangle is used to compute the area of a triangle if the input is valid. Use Heron's formula (provided in textbook exercise 2.19) to compute the area of the triangle (do not use any other formula). Notice that method isvalid() is used to validate the input before attempting to compute the area. See listings 6.10 and 6.11 (page 224) on how to write 2 programs

(main program and test program). Design the test program main method (all input and output is handled by the main method) such that it allows the user to re-run the program with different inputs ((i.e., use a loop

structure). Document your code and organize the outputs properly using appropriate formatting techniques. Submit both programs to the same Assignment Submission folder.
