Thread: 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.

Hints:

• 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

What have you done to solve this? Post some code and we can help you out but I will not just give you this answer.
