探讨泛型继承与接口实现的高级应用
本文深入解析了泛型在继承与接口实现中的高级应用，通过具体示例展示了如何在Java中利用泛型特性进行类型安全的代码复用与抽象，包括子类的泛型扩展与接口泛型的实现，旨在提升开发者对泛型概念的理解与实践能力。
泛型的继承或实现
public class Parent<T1, T2>
{
private T1 foo1;
private T2 foo2;
public T1 getFoo1()
{
return foo1;
}
public void setFoo1(T1 foo1)
{
this.foo1 = foo1;
}
public T2 getFoo2()
{
return foo2;
}
public void setFoo2(T2 foo2)
{
this.foo2 = foo2;
}
}
public class Child<T1, T2, T3> extends Parent<T1, T2>
{
private T3 foo3;
public T3 getFoo3()
{
return foo3;
}
public void setFoo3(T3 foo3)
{
this.foo3 = foo3;
}
}
public interface ParentInterface<T1, T2>
{
public void setFoo1(T1 foo1);
public void setFoo2(T2 foo2);
public T1 getFoo1();
public T2 getFoo2();
}
public class ChildClass<T1, T2> implements ParentInterface<T1, T2>
{
private T1 foo1;
private T2 foo2;
public void setFoo1(T1 foo1)
{
this.foo1 = foo1;
}
public void setFoo2(T2 foo2)
{
this.foo2 = foo2;
}
public T1 getFoo1()
{
return this.foo1;
}
public T2 getFoo2()
{
return this.foo2;
}
}
