用java实现字符串的部分应用

/*项目3：设有英文短文如下，统计输出以字母 w 开头的单词数；统计输出单词中含“or”字符串的单词数；统计输出长度为 3 的单词数。
Last fall I walked with a friend in hometown.
He was recognized as the most stupid among my childhood playmates,
but he has now been Number One in an enterprise.
When we came to a fork, a blind man walked from another direction.
Testing the road with his bamboo pole, the blind man was walking very slowly towards the road we were going to.
I chatted with my friend as we were walking.
I talked about my five job-hoppings within two years and the experiences I was still struggling in the plight now.
My friend nodded and smiled, but he kept silent all along.
After a while, I occasionally looked back and found the blind man had vanished.*/
