    Default Can anyone try this for me!!!

    Write a program to read the height and width of a triangle from the user using a Scanner. The area of the triangle should be calculated and printed. All numbers should be read in as whole numbers (int).
    The area of a triangle is (base * height * 0.5).
    The output should look something like this:
    Please enter the height of the triangle
    17
    Please enter the base of the triangle
    19
    The area of the Triangle is 161.5

    Does it work? Do you get errors? Please post the full text of any error messages.
    If it executes, does it print out the correct answer?
