//Class scopes are GLOBAL but METHOD scope is LOCAL

//Core concepts of Java

/* * Multiline comments * Comments - are two types: 1)Single-line comment // * Class - is nothing but a blueprint/design/template * to create Object /end product * What do we find inside Class? * - Inside the class we find * 3 things/ class members: 1) States - Properties/ Attributes/ Fields * 2) Behaviors -> Methods/Actions/Functions * 3) Main() methods * Variable - is nothing but a container that stores/hold data */

String name = "Tesla";

//Strings go inside quotation marks

int price = 100000;

// integer is a complete number These are states

public void run() {

//It is method and the Scope of the method starts here //Method is a block of code(s) that only runs/executes //when it is called by name

System.out.println("This is run method");

//Every Java code/program //end/terminates with a semicolon

}

////Scope of the method ends here

//Entry point in Java //What is the purpose of creating Object? // The purpose of creating object is to access/use all the // properties/States and methods/behavior of the class

Car car1 = new Car();

//How can I access/use the methods and properties // I can access the methods and properties creating object. Then, I have to use 'reference variables' to the object // with dot(.) operator

car1.stop();
