please solve it ASAP solve it quickly to get you thumbs up directly in java please

no information need its complete

LABO2: Compute the time complexity for each method in studentChart class in the previous lab. Add the following methods to the class studentChart and compute the time complexity for these methods. Public void sortByAverage(): this methods sorts the students according to their average in an ascending order. Public void sortByName(): this methods sorts the students according to their names in an ascending order. Public Boolean binarySearhByID(Student st): the method searches for Student st in the list of students using binary searching algorithm and returns true if the student exists in the list, otherwise returns false. Submission Guidelines: 1. Add these methods to the class StudentChart.java 2. The classes are bagged in a zip or rar file single, called Labo2.rar or Labo2.zip 3. Your program should be bugless and executable. LABO2: Compute the time complexity for each method in studentChart class in the previous lab.
