split的简单运用

public class Test { 
 public static void main(String args[])
 {
  String name=null;
  String pwd=null;
        StringBuffer sb=new StringBuffer();
        sb.append("username=");
        sb.append(123);
        sb.append("&password=");
        sb.append(235);
        String info=sb.toString();
        //先分段开来，然后变成username=123和password=256;
        String hello1[] = info.split("&");
     ／＊   for(int i=0;i<hello1.length;i++)
        {
         System.out.println(hello1[i]);
        }＊／
    
        for(int i=0;i<hello1.length;i++)
        {
         String hello2[]=hello1[i].split("=");

         
            if(hello2[0].equals("username"))
               {
                   name=hello2[1];
               }
               if(hello2[0].equals("password"))
               {
                   pwd=hello2[1];
               }         
        }
        System.out.println(name);
        System.out.println(pwd);
 }
}
