[resolved] string comparison

Anonymous — Wed, 08 Aug 2012 09:54:33 GMT

I have the below code :
================================================================================================================
String fileName;
String delim = "-";
globalMap.put("basename",input_row.basename); //system
globalMap.put("md5",input_row.md5); //System calculated MD5
fileName = ((String)globalMap.get("tFileList_1_CURRENT_FILE"));
String tokens[] = fileName.split(delim); //seperate by delimiter of "-"
StringBuffer sb = new StringBuffer(128); //create string buffer
for (int i = 0; i < tokens.length; i++) //iterate through filename
{
if(i ==1)
{
context.file_type = tokens ; //Get file load name from filename
}
if (i == 7) //get MD5 String
{
globalMap.put("_md5", tokens.substring(0,32));
context.md5_message = (String)globalMap.get("_md5"); //assign file MD5 to context
}
}
context.basename_message = (String)globalMap.get("basename");
context.guid_message = context.basename_message.substring(25,59);
System.out.println("Assigned Contexts from received file");
System.out.println(context.guid_message); //GUID (IN FILENAME)
System.out.println(context.md5_message); //MD5 (IN FILENAME)
System.out.println(context.basename_message); //FILENAME
System.out.println(context.file_type); //TYPE OF LOAD

System.out.println("Actual Values");
System.out.println((String)globalMap.get("md5"));
System.out.println(((String)globalMap.get("tFileList_1_CURRENT_FILE")));
//(String)globalMap.get("md5") == context.md5_message
if ((String)globalMap.get("md5") == (String)context.md5_message)
{
System.out.println("ITS a MATCH");
}
else
{
System.out.println("Waaaah, waaaah , waaaahh");
}
================================================================================================================
when i compare , the 2 strings above:
if ((String)globalMap.get("md5") == (String)context.md5_message)
it never proves true:
I have pushed my results to screen :
================================================================================================================Assigned Contexts from received file

Waaaah, waaaah , waaaahh
================================================================================================================
on my output the strings are the same ...
what am i missing ,
