匿名內部類怎麼獲取外部外部局部變量

public class test {
// public String name;
public void say(String name) {
new RunnableWithReturn() {

        @Override
        public Object execute() {
            System.out.println(name);
            return null;
        }
    };
}

}

interface RunnableWithReturn {

public abstract Object execute();

}

最佳回答：

// public String name;
public void say(final String name) {
new RunnableWithReturn() {
@Override
public Object execute() {
System.out.println(name);
return null;
}
};
}

添加參數 final
