最近在学 Java的编程思想这本书
可到了第8章
匿名类这里，练不下去了，
书上匿名类的例子
在eclipse 中报错：
package Thinkinginjava;
public SimpleInterface get() {
return new Inner();

public class E13_InnerClassInMethod {
   public SimpleInterface get() {
     class SI implements SimpleInterface{
     public void f() {
     System.out.println(
     "E13_InnerClassInMethod.f");
     }
     }
     return new SI();
     }
     public static void main(String args[]) {
     SimpleInterface si =
     new E13_InnerClassInMethod().get();
     si.f();
     }
}

报错如下：
SimpleInterface cannot be resolved to a type
这是怎么回事啊
eclipse中不能用吗？

Due to the fact that you are using Eclipse as your IDE to develop your Java program, you should notice that IDE informs you of those compiling errors.

Check your first interface which only contain one parenthesis. (an oversight from your code). In order words, all the Java programming "components", including if, else, try, catch, class, interface, etc.... must be included an open and a close parentheses.

When I was a kid I used to pray every night for a new bike. Then I realized that The Lord doesn't work that way, so I stole one and asked him to forgive me.
