What are best practices for working with toString?

The toString() method in Java is used to return a string representation of an object. It is essential for debugging and logging, as well as for providing informative output when dealing with object instances.

// Example of overriding toString() in Java

public class Person {
    private String name;
    private int age;

    public Person(String name, int age) {
        this.name = name;
        this.age = age;
    }

    @Override
    public String toString() {
        return "Person{name='" + name + "', age=" + age + "}";
    }

    public static void main(String[] args) {
        Person person = new Person("John", 30);
        System.out.println(person.toString()); // Output: Person{name='John', age=30}
    }
}
