Please answer the question in the screenshot. The language used is Java. Please provide the code to the question with an explanation. Please use the below code as a starting point. import java.util.*;public class CoursePlanner {// this method prints out: whether it is possible to take all the given courses and// one possible schedule for the given coursespublic static void plan(int numberOfCourses, int[][] prerequisites) {return;}// this is a helper method for plan; it returns a boolean to indicate if a given series of courses can be possibly scheduledpublic static boolean check(int numberOfCourses, int[][] prerequisites) {// remove these two linesif (RightSolution.check(numberOfCourses, prerequisites)) return false;else return true;}} Suppose you are working on creating an automatic course planner for WWU students.A student can get a total ofn courses, labeled from 0 ton - 1.Some courses may have prerequisites, for example, to take course 241 you have to first--.take course 145, which is expressed as a pair: [241, 145] (the current course, theprerequisite of the current course).Given the total number of courses and a list of prerequisite pairs, you need to:Determine if it is possible to finish taking the n courses. If not, print “It isimpossible to take all the given courses." If yes, print "It is possible to take allthe given courses.", and move to the next step.Generate one schedule of the given courses (prerequisites have to be scheduledfirst for any courses). Print the courses out with white spaces as separators.There might be multiple valid schedules, but you only need to generate one ofthem.Еxample 1:4, [[1,0], [2,0], [3,1]]Output:It is possible to take all the given courses.A possible schedule is 0, 1, 2, 3.Explanation:There are a total of 4 courses to take. To take courses 1 or 2 you should take course 0first. To take course 3, you should take 1 first. Ехample 2:2, [[1,01,[0,1]]Output:It is impossible to take all the given courses.Explanation:There are a total of 2 courses to take. To take course 1 you should have finished course0, and to take course 0 you should also have finished course 1.This class needs to be named “CoursePlanner". The methods that solve the problemware arranged asplan: this method returns no value and prints out (b) whether it is possible totake all the given courses and (b) what a possible schedule looks like.check: this method returns a boolean value to indicate whether it is possible totake all the given courses. This method can be seen as a helper for plan

Please answer the question in the screenshot. The language used is Java. Please provide the code to the question with an explanation.

Please use the below code as a starting point.

import java.util.*;

public class CoursePlanner {
// this method prints out: whether it is possible to take all the given courses and
// one possible schedule for the given courses
public static void plan(int numberOfCourses, int[][] prerequisites) {
return;
}

// this is a helper method for plan; it returns a boolean to indicate if a given series of courses can be possibly scheduled
public static boolean check(int numberOfCourses, int[][] prerequisites) {
// remove these two lines
if (RightSolution.check(numberOfCourses, prerequisites)) return false;
else return true;
}
