record java

// New feature since jdk 14 
// BEWARE - IMMUTABLE CLASS, you cannot use setters (Bad thing)
// Alutomatically creates toString, setters and constructors with initialized arguments (Good thing)

// Record.java
public record Record(String name, int age) {}

// Main.java
public class Main {
    public static void main(String[] args) {
        // Create an IMMUTABLE object of Record using the constructor 
        Record record = new Record("John", 30);

        // Printing the object using toString() method will print all the argument values
        System.out.println("Record object: " + record);
        
        // You cannot explicitly set values to fields of a record after initialization
        // record.setName("Alice"); // This will cause a compilation error
        
        // You can access the components directly (getters only)
        System.out.println("Name: " + record.name());
        System.out.println("Age: " + record.age());
    }
}

what is record in java

Comment

0

// In Java, a record is an immutable class that encapsulates a set of related data fields.
// It provides useful methods like constructors, accessors, and equals/hashCode implementations.
// Records are introduced in Java 16.

public record Person(String name, int age) {
    // Additional methods, if needed
    
    public void printDetails() {
        System.out.println("Name: " + name);
        System.out.println("Age: " + age);
    }
}

// Usage of the record
Person person = new Person("John Doe", 25);
person.printDetails();
