How to divide two strings in Java, if ValueOF or Integer.parseInt are not working?

Question

i must divide the results of two strings in Java. I hava tried valueOF, parseUnsignedInt and other methods, but the problem is, that for the first string they does not work. The strings are getText() results from a certain web element, which i am getting using Selenium. Here is my code

System.out.println( Integer.valueOf(st) /Integer.parseUnsignedInt( element.getAttribute("innerHTML").substring(16) ));

Here is error which i have

Exception in thread "main" java.lang.NumberFormatException: For input string: "10,768"
    at java.base/java.lang.NumberFormatException.forInputString(NumberFormatException.java:65)
    at java.base/java.lang.Integer.parseInt(Integer.java:652)
    at java.base/java.lang.Integer.valueOf(Integer.java:983)
    at com.company.Main.main(Main.java:64)

10768 is the string number for my String st How can I handle this situation to get the division number correctly?

I am getting the number from a web element, so I can't change the comma — , Mar 21 '19 at 13:39
Then use a *regex* to replace that comma with a *blank* space before parsing it. You can't convert a `,` to an `int` — Nicholas K, Mar 21 '19 at 13:39
I believe you should be more concrete - your input string looks like double value. What your expectation of parsing: ```10,768d``` : ```10``` :```11```:```10768``` — Ivan Baranuk, Mar 21 '19 at 13:47
Maybe of low reliabilty, but you could do `int num = Integer.parseInt(st.replace(",", ""));` to have the number without a comma. This may lead to problems in some situations. — deHaar, Mar 21 '19 at 13:53

You can convert the String value containing the comma into an integer using:

int value = NumberFormat.getNumberInstance(java.util.Locale.US).parse(element.getAttribute("innerHTML").substring(16));

And then you can use this value for your division like:

System.out.println(Integer.valueOf(st)/value);
