Association:

There are two-way and one-way.

The two-way association between class An and class B can be an attribute of each other.

One-way means that one of the classes acts as an attribute in the other class

For example:

Public class Person {

Hourse head=new Hourse ()

}

Dependence:

Dependency is only one-way, and there is no attribute problem. For example, class A depends on class B, which indicates that there are three types of B in class A:

First, class B is global.

Second, class B is instantiated in class A.

Third, class B is passed as a parameter.

Public class Person {

Public void buy (Hourse hs) {

}

}
