1. Write down Java program to implement class UML diagram and methods: 15 Course courseName : String - sudents : String[] - numberOfStudents : int + Course(courseName : String) + getCourseName() : String + addStudent(student: String) : void + dropStudent(student : String) : void + getStudents(): String[] + getNumberOfStudents : int + clear() : void i. Array students will keep the names of students, consider the names are unique and there are 10 students. ii. addStudent() adds a student in the Course, by adding student if the number is more than the array length, the array length will be doubled to accommodate more students. You can use System.arraycopy utility for it. ini. dropStudent() will drop a student from Course, the empty space due to drop is filled by shifting the remaining students towards the null space and the last array element will be made null. iv. clear() will clear the array list. v. Add three students S1, S2 and S3 to CSE 215.2, print out those students, then drop student Sl and print out those student list again
