public interface IMethodCallback
{
    boolean Execute();
}

...

IMethodCallback callback = new IMethodCallback
            {
                boolean Execute()
                {
                    return false;
                }
            };

这会导致错误。如何在Java中制作类似的东西？

最佳答案

您会错过构造函数的括号:

IMethodCallback callback = new IMethodCallback()
{
    public boolean Execute()
    {
        return false;
    }
};
