public static void main(String[] args) {

//Print in the console.
System.out.println("Printing String...");
//Basics.
- Pink letters are keywords. ( public, static, class, void... )
- Compiler will always start with the 'main' mathod.
- use ';' after each line of code.
- 'void' is the basically how we tell that we returning nothing. if we want to return a number? then mention 'int' instead of 'void'.
int a = 10;
// 'int' is Integer.
String name = "Karan";
// 'String' is string.
----------------------------
// Transfer data/methods within classes.
public class Parent {
// This is the parent Class.
public static void main(String[] args){
Methods m = new Methods;
//Methods is the class name.
// 'm' is the oject.
m.ValidateHeader();
// 'm.' will provide 'built in' and custom methods available in the 'Methods' class.
m.ValidateFooter();
// It will return 'Done Amigo' as programed in method.
}
}
publick class Methods {
//This is the 'Methods' class ( child class)
// We won't be using 'main' method here as we are just sending the data.
public void ValidateHeader(){
//Example of an Method.
// 'void' since we are not returning anything.
}
public String ValidateFooter(){
//Example of an Method.
// 'String' as we are returning string
return "Done amigo"
}
public int ValidateFooter2(){
//Example of an Method.
return 200;
}
}
