The class should contain the following methods: * A constructor that accepts values for a, b, and c. * public double getA() * public double getB() * public double getC() * public double evaluate (int x) * will return the value of the expression at point x * public double discriminant() - that will return (b2 - 4ac) * public boolean isImaginaryRoots() - roots are imaginary if (b2 - 4ac) < 0 * public boolean isRealRoots() - roots are real if (b2 - 4ac) >= 0 // these methods can only be invoked if the roots are not imaginary * public float firstRoot() * public float secondRoot() * public boolean isPerfectSquare(); // If the first and second roots are equal * Try to override the toString methods * Write a sample main program that will work as shown below. Example output:…CODE IN JAVA Please look at the attached image for the information about the format the code should be in It should have 2 java files one acting as server and other the client Design and implement an application that reads a sequence of up to 25 pairs of names and postal (zip) codes for individuals. Store the data in an object of a class called “NameAndZip”, designed to store a first name (String), last name (String), and a postal code (int). Create a driver class called “NameAndZipList”. Assume that each line of input will contain two strings followed by an integer value. You will then create an object for each line read in and store that object in an array of NameAndZip objects. After the Names and Codes have been entered, print the list in an appropriate format to the screen using the toString method in the NameAndZip class. To test the program enter 3 names and codes.
