In this post under Java, I will show with example how to add and access static members in Java Record.

Below is the structure of “Student” Record with static members

Student

1 package core.record;
2 
3 public record Student(int id, String name, int age) {
4     public static int noOfStudents;
5     public static void display() {
6         System.out.println("Number of students: " + noOfStudents);
7     }
8 }

As shown in the above code, we can add static members to Record in the same way we add to a Class.

Below is the main class that shows how we can access the static members of the Record.

Main class

package core.record;

public class Example2 {
    public static void main(String[] args) {
        Student student = new Student(1, "john doe", 40);
        Student.noOfStudents = 1;
        System.out.println(student);
        Student.display();
    }
}

As shown in the above main class, accessing static members of Record, is similar to way we access static members of a class.

That is we don’t need instance of Record, the Record name itself will suffice.

In this way we can add and access static members of a Record
