In Spring Boot, you can use the sort method from Java’s Collections class to sort data. Here is a simple example:

  1. To start, create a Java class, for example Student, to represent student information, including the student’s name and score.
public class Student {
    private String name;
    private int score;

    // getter and setter methods

    // constructor
}
  1. Create a list containing information about students and add some student objects.
List<Student> students = new ArrayList<>();
students.add(new Student("Alice", 80));
students.add(new Student("Bob", 70));
students.add(new Student("Charlie", 90));
students.add(new Student("David", 75));
  1. Sort the list of students using the sort method of the Collections class. You can use the Comparator interface to specify the sorting rules.
Collections.sort(students, Comparator.comparingInt(Student::getScore));

The above code sorts the list in ascending order based on the students’ scores. If you want to sort in descending order, you can use the reversed method.

Collections.sort(students, Comparator.comparingInt(Student::getScore).reversed());
  1. Finally, iterate through the sorted student list and check the sorting result.
for (Student student : students) {
    System.out.println(student.getName() + ", " + student.getScore());
}

By following the steps above, you can sort data in Spring Boot. Depending on your specific requirements, you can use different sorting criteria and attributes to sort the data.
