//This is an example of a class:
public class Test{
public static void main(String[] args) {
System.out.println("Test");
}
}
//For more info a class is kinda like a blueprint for creating objects.
//Almost all of the code(Except imports, etc) are put in the class.The Object class is the parent class of all the classes in java by default.In
other words, it is the topmost class of java.
The Object class is beneficial if you want to refer any object whose type you
dont know. Notice that parent class reference variable can refer the child
class object, know as upcasting.class Student{
//defining fields
int id;//field or data member or instance variable
String name;
//creating main method inside the Student class
public static void main(String args[]){
//Creating an object or instance
Student s1=new Student();//creating an object of Student
//Printing values of the object
System.out.println(s1.id);//accessing member through reference variable
System.out.println(s1.name);
}
} java classes
