Create a class for linear regression. The class should contain an array to store the sample data coordinates of $(x,y)$ and $n$ which is the number of sample data. You may assume the maximum number of data points is $100.$ The class should contain methods to calculate $a,b,r($correlation$)$ and predict the value of $y$ for an input of $x.$ Construct an object of this class and assign the values of $(x,y)$ in the main program. Call the methods in the main program to calculate $a,b,r$ and predict the value of $y$ for an input of $x.($Java Program$)$
