I forgot to write about the scanner, so I'm going to do that now.

Basically, a scanner is used to get information from the user. At this stage, the scanner will be used only to gather information from the keyboard. Here's how it works.

import java.util.Scanner;
class Class1{
	public static void main(String args[]){
		Scanner input = new Scanner(System.in);
		System.out.println("Enter some text:");
		System.out.println("The

Instead, you'd have to do something like this:

boolean blue = true;
String print = blue ? "blue" : "red";
System.out.println(print);

Well, I've finally finished watching and summarising (in this thread) the first twenty tutorials of TheNewBoston's Java Programming Tutorial series. I've previously watched all 87 tutorials, but never summarised any of them to the point that the information stuck in my head long enough for me to retain.

I plan on doing the same sort of thing for the next 67 tutorials and then into the Intermediate Java tutorials.

Thank you to everyone who has helped me out along the ...

Basically, I like to look at Conditional Operators as a quick way of implementing an If Statement. That's really all they are. Take a look at this code.

class Class1{
	public static void main(String[] args){
		int age =50;
		System.out.println(age > 30 ? "You are quite old!" : "You are still young!");
	}
}

You can see that we've initalised an integer with the value of 50. Our Conditional Operator ...

We can use a constructor to quickly initialise variables as soon as our object is created. If you haven't read the above post, please do - you will become familiar with the code we're using for these examples.

Here's Class1.

class Class1{
	public static void main(String args[]){
		Class2 class2Object = new Class2("Tony");
		class2Object.outputName();
	}
}

You can see what we've done here is ...
