    Default Need help (Method)

    This is the question
    Write method distance to calculate the distance between two points (x1, y1) and (x2, y2). All numbers and return values should be of type double. Incorporate this method into an application that enables the user to enter the coordinates of the points.


    The distance between two points can be calculated by taking the square root of

    ( x2 - x1 )2 + ( y2 - y1 )2

    Use Math class methods to compute the distance.

    Your output should appear as follows:

    Type the end-of-file indicator to terminate

    On UNIX/Linux/Mac OS X type <ctrl> d then press Enter

    On Windows type <ctrl> z then press Enter

    Or Enter X1: 1

    Enter Y1: 1

    Enter X2: 4

    Enter Y2: 5

    Distance is 5.000000

    Type the end-of-file indicator to terminate

    On UNIX/Linux/Mac OS X type <ctrl> d then press Enter

    On Windows type <ctrl> z then press Enter

    Or Enter X1: ^Z

    Look at the question given and try to solve it on paper first. Modify that into
    pceudocode (spelling?) and create a workable algorithm from that.
