    Default Convert Formatted String to Integer

    Hi,
    Appreciate any help on this issue.
    If I use the class DecimalFormat to format long number, how can I convert it back to integer?


    DecimalFormat longFormat = new DecimalFormat("#,###");  
    		long testLong=11000;
     
    		String strLong=longFormat.format(testLong);
    		System.out.println("NUM : " + strLong);
     
     
    		//Assume that at this point I don't have 
    		//testLong, I have only the strLong value...
    		long newLong=Long.parseLong(strLong) * 2;
     
    		//java.lang.NumberFormatException: For input string: "11,000

    Look at the parse method.
    If you don't understand my answer, don't ignore it, ask a question.

    Did you try the DecimalFormat class's parse method?

    Did you post the String you are trying to convert?
    If you don't understand my answer, don't ignore it, ask a question.

    Hi,
    Thanks I used the parse method, and it seems working.

    long newlong= longFormat.parse(strLong).longValue();
