In our daily life we describe a thing by the languange,So does the java.In java we use the class to describe the thing in the world
A class includes two parts:the properties and the method
Such as how we make a new car using the java languange:
At first we must define the car's common properties and the method
for exmaple:
class Car{
//properties
int nums=4;
String color="color";
//method
void run(){
System.out.println("car's tyre num:"+num+"car's color:"+color);
}
}
