Write a Java Program to Print object of a class

In Java, an object is an instance of a class.

It contains data and methods that define its behavior.

In this tutorial, we’ll discuss how to print an object of a class in Java.

To print an object of a class, we first need to create a class.

For this example, let’s create a simple class called “Person”.

The Person class will have two properties, “name” and “age”, and a constructor to initialize those properties.

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

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

Now that we have our class, we can create an object of it in our main method.

public static void main(String[] args) {
    Person person = new Person("John", 30);
}

To print the object, we can simply use the System.out.println method and pass the object as an argument.

System.out.println(person);

However, if we try to print the object now, we’ll get a memory address instead of the values of the properties.

To print the values of the properties, we need to override the toString method of the Person class.

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

Now if we try to print the object again, we’ll get the values of the properties instead of the memory address.

Person person = new Person("John", 30);
System.out.println(person); // prints "Person{name='John', age=30}"

In conclusion, to print an object of a class in Java, we need to create a class with properties and a constructor, create an object of the class, and override the toString method to print the values of the properties.
