public static void main(String[] args) { //Basic set up. } //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; } } -----------------------------
