problems running recursion. [SOLVED]
The program is supposed to check the summary total of a text document:

Sample
SUMMARY 01/29/2011 \$-74.30 4
SUMMARY 01/24/2011 \$-104.69 2
SELL 01/27/2011 \$88.88

the number after the amount is the number of sub entries which make up that summary. The problem I am having is when I try to run a recursion, after the second thread completes instead of returning to the first thread and finishing it, it just returns the current count and terminates the program.

any help would be greatly appreciated!

here's the segment I am having trouble with,

he full code can be found at http://www.pastebay.net/307448

here's the segment I am having trouble with,

Code JAVA:

``` //method checks the accuracy of the summaries public static double subCheck(int sumNum, double subTotal, Scanner in) throws IOException{   String date; String amountString =null; int x=sumNum; double total=subTotal; double amount=0; double count=0; double tTotal=0;   while (x>0){ // calls lineCheck to determine the first token of the line amountString = lineCheck(in); //if summary is returned as the first token method autoNum is //called to get the number of sub entries that make up its total if(amountString=="SUMMARY"){ date = lineCheck(in); total = amountNum(in); tTotal=total; //number of sub entries is stored as x String X=subNum(in); //string x is changed to an int x=Integer.parseInt(X); //amountString is converted to null amountString =null; if(x>0) //method calls its self to check summary total return subCheck(x,total,in); } //checks the value of buy and sell, then adds the value into count if(amountString!="SUMMARY"){ date=amountString; amount=amountNum(in); count=amount+count; x--; //temporary, prints out count so I can check that the program is making the proper calculations System.out.println(count); }   }   return count; }```
