This is the last one of the test series. It also about the regular expressions.

 1 public   class  testreplaceall
 2 {
 3      public   static   void  main(String args[])
 4      {
 5         String s  =   " aaaaa= " ;
 6         s =  s.replace( " = " , "" );
 7         System.out.println(   "s  is  "+s );
 8         s =   " aaaa. " ;
 9         s =  s.replaceAll( " \\. " , "" );
10         System.out.println( "s  is  "+s );
11         s =   " aaaa. " ;
12         s =  s.replaceAll( " . " , "" );
13         System.out.println( "s  is  "+s );
14     }
15 }
16         

The . stand for all letter, and the Escape character is \\

Continue with my JAVA test series.

 1 import  java.util.regex.Pattern;
 2
 3 public   class  testmatch
 4 {
 5      public   static   void  main(String args[])
 6      {
 7          boolean  valid  =   false ;
 8          // String s = 
 9         valid  =  Pattern.matches( " hoho.* " , " hoho123 " );
10         System.out.println(valid);
11         valid  =  Pattern.matches( " hoho.+ " , " hoho " );
12         System.out.println(valid);
13     }
14 }

Record some code sum-up on this week.

1、  SpitTest --- learned from www.javatx.cn Welcome to this website, I master the J2SE section J

 1 public   class  SpitTest  {
 2
 3 /** */ /**
 4  *  @param  args
 5   */
 6      public   static   void  main(String[] args)  {
 7
 8         String info  =    " elementX1,elementY1,elementZ1 "
 9                         +    " \\r\\n "
10                         +    " elementX2,elementY2,elementZ2 "
11                          +      " \\r\\n " ;
12           info  =  info.replace( " \\r\\n " ,  " , " );
13         String str[]  =  info.split( " , " );
14          for  ( int  i  =   0 ; i  <  str.length; i ++ )  {
15             System.out.println(str[i]);
16         }
17     }
18 }

I think it’s a very good idea to solve the problem, if I do it, I may use the split twice.

        Keyword: directory structure

There are many articles that introduce how to configure the development environment, so I don’t mention it. But in my own experience, I meet the other question, it’s the directory construct of the MVC.

M-Model   In this, it refers to the JavaBeans.

V-View    In this, it refers to JSP files

C-Control   In this, it refers to Servlet.

In eclipse with the WTP plug-in or myeclipse(recommended) , you can new a web project, and then new a JSP, and new a servlet if you need, but for the Javabean, you should new a class, and in the following windows select a new package, such as myBean to store the JavaBean.

Now the directory structure is like this:

---|WEB-INF |---web.xml
    |                |---lib

    |                |---classes|---myServlet.class (this is the servlet)

    |                               |---myBean  ---myBean.class  (this is the JavaBean)

    |JSPs

OK, Good Luck J
