学习泛型的方法总结

1.

public class GenericFoo<T>
{
	private T foo;
         set{};get{};
}
GenericFoo<Boolean> foo1 = new GenericFoo<Boolean>();
GenericFoo<Integer> foo2 = new GenericFoo<Integer>();

2.

public class Generic<T1, T2>
{
	private T1 foo1;

	private T2 foo2;
         set{};get{};      
}
Generic<Integer, Boolean> foo = new Generic<Integer, Boolean>();

3.

public class Generic2<T>
{
	private T[] fooArray;
         set{};get{};      
}
Generic2<String> foo = new Generic2<String>();

4.

public class ListGenericFoo<T extends List>
{
     private T[] fooArray;
         set{};get{};      
}
		ListGenericFoo<LinkedList> foo1 = new ListGenericFoo<LinkedList>();
		ListGenericFoo<ArrayList> foo2 = new ListGenericFoo<ArrayList>();

5.
（父类）

public class Parent<T1, T2>
{
	private T1 foo1;

	private T2 foo2;
        set{};get{};  
}

（子类）

public class Child<T1, T2, T3> extends Parent<T1, T2>
{
	private T3 foo3;
        set{};get{}; 
}

6.

public class ChildClass<T1, T2> implements ParentInterface<T1, T2>
{
	private T1 foo1;

	private T2 foo2;
         set{};get{}; 
}

(接口)

public interface ParentInterface<T1, T2>
{
	public void setFoo1(T1 foo1);

	public void setFoo2(T2 foo2);

	public T1 getFoo1();

	public T2 getFoo2();
}
