The method header is:public static double[] getIntersectingPoint(double[][] points)The points are stored in a 4-by-2 two-dimensional array points with (points[0][0], points[0][1]) for (x1, y1). The method returns the intersecting pointor null if the two lines are parallel. Write a program that prompts the user to enterfour points and displays the intersecting point.arrow_forwardProblem: Write a method that will determine whether a given value can be made given an array of coin values. For example, each value in the array represents a coin with that value. An array with [1, 2, 3] represents 3 coins with the values, 1, 2, and 3. Determine whether or not these values can be used to make a desired value. The coins in the array are infinite and can only be used as many times as needed. Return true if the value can be made and false otherwise. Dynamic Programming would be handy for this problem. Data: An array containing 0 or more coin values and an amount. Output: Return true or false.
