Using multiple classes

class jamesprogram {

	public static void main(String args[]){

		cat catObject = new cat();


In the above we create a new cat object called catObject. Once we have created a new object, we can access the methods of that class (simpleMessage()) in this example. The syntax before the = operator describes the ‘name of the class we are creating an object from and the declared name of this new object (cat catObject).

// the public means anything can use it, it's 'public'
public class cat {
	// public (anyone can use it)
	// void (this method's going to do something but not
	// return anything
	public void simpleMessage(){

		System.out.println("Another class");


Not suprisingly, this outputs the text

Another class
