What is a class?
In Java, all code is associated with a class. Classes have fields and methods. Here is an example of two simple classes:
Cat.java
public class Cat{
private int age;
private String name;
public Cat(String name, int age){
this.name = name;
this.age = age;
}
public String getName(){
return name;
}
public String sayHello(){
return "Hello World! My name is " + name + " and I am " + age + " years old."
}
}
CatsTheMusical.java
public class CatsTheMusical{
public static void main(String[] args){
Cat mist = new Cat("Mr. Mistoffelees",8);
System.out.println(mist.sayHello);
}
}
