generic
Hello   every   body: 
          I   used   java   1.5   ; 
 there   is   something   wrong   in   the   last   line;      
 ////////////////////////////////////////////////////////// 
 import   java.util.HashMap; 
 import   java.util.Map;   
 public   class   TestMap   { 
 	public   static   void   main(String   args[])   {		 
 		args[0]   =    "a "; 
 		args[1]   =    "hello "; 
 		Map <String,Integer>    map   =   new   HashMap <String,Integer> (); 
 		for   (int   i   =   0;   i    <   args.length;   i++)   { 
 			map.put(args[i],   i); 
 		} 
 		Integer   position   =   map.get( "hello ");      //   here   something   wrong:   The   type   java.lang.Object   cannot   be   resolved.   It   is   indirectly   referenced   from   required   .class   files               
 	} 
 }   
 Who   can   help   me? 
 Thank   you!
