I’m working on a java question and need an explanation and answer to help me learn.

Consider the following classes:

The first class represents a 2D point. The x and y fields represent the x and y coordinates of the point. The method isColinear returns a Boolean value indicating if the point and two arguments points are all in a straight line.

The second class represents a line. The fields represent points on the line. The getLength() and getMid() methods calculate the distance between the two line points and the midpoint between them (acting as if the points represents a line segment). The getM() and getB() methods calculate that line’s slope and y-intercept, respectively (acting as if the line is infinite).

Each object-oriented program must have its main class prompt the user to manually enter the x and y coordinates of four (4) points. The first two values entered should make the x and y coordinates of the point of one line, and the second two values make the x and y coordinates of the line’s other point. The remaining four values entered should be the coordinate positions of the second line’s points.

Your program must make two-line objects from the four points. It must use the methods in each object to display the following information:

• Equation of each line in the form y = mx + b
• The length of each line segments
• Whether the lines are parallel
• Whether the point on each line is colinear with the points on the other line
