truts2框架正则表达式校验器的名字是()
A: interceptor
B: error
C: regex
D: expression
A: interceptor
B: error
C: regex
D: expression
举一反三
- regex的作用是删除不匹配的正则表达式()
- 11. String test = “Test A. Test B. Test C.”; 12. // insert code here 13. String[] result = test.split(regex); Which regular expression inserted at line 12 will correctly split test into “Test A,” “Test B,” and “Test C”?() A: String regex = “”; B: String regex = “ “; C: String regex = “.*“. D: String regex = “\\s” E: String regex = “\\.\\s*”; F: String regex = “\\w[ \.] +“;

- C语言中,循环结构for(表达式1;表达式2;表达式3)中表达式2必须是条件表达式
- for(表达式1:表达式2:表达式3)语句中表达式1通常用来表达?A.()始化循环变量()B.()系表达()C.()辑表达()D.()循环变量递增强或递减
