第一题有错误，number没声明，不知道这个是干什么的，好几行都没用，结果是：4.0
第二题：前台：Scriptlet test page
Hello World. This is a scriptlet test 0
Hello World. This is a scriptlet test 1
Hello World. This is a scriptlet test 2
后台：This goes to the System.out stream 0
This goes to the System.out stream 1
This goes to the System.out stream 2
第三题：i是随机的，转到哪一个都有可能
第一个写错了吧 不过结果值应该是4.0；
第二个 <b>Hello World. This is a scriptlet test 0</b><br>
This goes to the System.out stream 0
<b>Hello World. This is a scriptlet test 1</b><br>
This goes to the System.out stream 1
<b>Hello World. This is a scriptlet test 2</b><br>
This goes to the System.out stream 2
第三个 是随机的 也就是说有可能是 跳转到test1.jsp 也有可能跳转到 test2.jsp
