How to put the contents of a file to a String of array in java -

i have string array contains records ,now have put records in file , have read values , have check records string array values.here string array..

 public final static string fields[] = { "fileid", "filename", "eventtype",         "recordtype", "accesspointnameni", "apnselectionmode",         "causeforrecclosing", "chchselectionmode",         "chargingcharacteristics", "chargingid", "duration",         "dynamicaddressflag", "ipbinv4addressggsn",         "datavolumefbcdownlink", "datavolumefbcuplink",         "qosinformationneg"}; 

i have put these records in map using these,,

 static linkedhashmap<string, string> getmetadata1() {   linkedhashmap<string, string> md = new linkedhashmap<>();   (string fieldname : fields) md.put(fieldname, "");    return md; 

}

now file

        fileid          filename         eventtype         recordtype         accesspointnameni         apnselectionmode         causeforrecclosing         chchselectionmode         chargingcharacteristics         chargingid         duration         dynamicaddressflag         ipbinv4addressggsn         datavolumefbcdownlink         datavolumefbcuplink         qosinformationneg  

now reading file function

static linkedhashmap<string, string> getmetadata() {       linkedhashmap<string, string> md = new linkedhashmap<>();     bufferedreader br = null;     try {          string scurrentline;         string file[];         br = new bufferedreader(new filereader("./file/huagprsconf"));          while ((scurrentline = br.readline()) != null) {            md.put(scurrentline, "");         }      } catch (ioexception e) {         e.printstacktrace();     } {         try {             if (br != null)                 br.close();         } catch (ioexception ex) {             ex.printstacktrace();         }     }       return md; } 

now 2 functions returing values in 2 different ways..the string giving

{fileid=, filename=, eventtype=, recordtype=, accesspointnameni=, apnselectionmode=, causeforrecclosing=, chchselectionmode=, chargingcharacteristics=, chargingid=, duration=, dynamicaddressflag=, ipbinv4addressggsn=, datavolumefbcdownlink=, datavolumefbcuplink=, qosinformationneg=}  

but file 1 getting values giving values big spaces..

{            fileid =,             filename=,             eventtype=,             recordtype=,             accesspointnameni=,             apnselectionmode=,             causeforrecclosing=,             chchselectionmode=,             chargingcharacteristics=,             chargingid=,             duration=,             dynamicaddressflag=,             ipbinv4addressggsn=,             datavolumefbcdownlink=,             datavolumefbcuplink=,             qosinformationneg=,             rattype=,             ratinggroup=,             resultcode=,             serviceconditionchange=,             ipbinv4address=,             sgsnplmnidentifier=,             timeoffirstusage=,             timeoflastusage=,             timeofreport=,             timeusage=,             changecondition=,             changetime=,.... on 

now when trying check 2 values using function not equal..

linkedhashmap<string, string> md1=getmetadata();     linkedhashmap<string, string> md2=getmetadata1();      if(md1.equals(md2)){         system.out.println(md1);     }else{         system.out.println("not");     }              

i cannot understand problem can help...

you should use scurrentline.trim() remove unnnecessary whitespace.
