Question

下面的JAVA代码出现泛型变量错误是什么原因啊 谢谢了

public class GenericFoo2<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 foo1;
}
public T2 getFoo2()
{
return foo2;
}
}
class GenericFoo2Demo
{
public static void main(String[] args)
{
GenericFoo2<Integer,String> foo=new GenericFoo<Integer,String>();
foo.setFoo1(new Integer(1));
Integer i =foo.getFoo1();
System.out.println(i);

}
}

Answer 1

GenericFoo2<Integer,String> foo=new GenericFoo<Integer,String>();

后面应该是

GenericFoo2<Integer, String> foo = new GenericFoo2<Integer, String>();

GenericFoo 改为GenericFoo2 你写错了。。
