java convert string with commas to long

To convert a String containing a number with commas as a thousands separator to a long value in Java, you can use the replaceAll method of the String class to remove the commas, and then use the Long.parseLong method to parse the String as a long value.

Here is an example of how you can convert a String with commas to a long value in Java:

String str = "1,000,000";
str = str.replaceAll(",", "");
long value = Long.parseLong(str);

In this example, we have a String called str that contains a number with commas as a thousands separator. We use the replaceAll method to remove the commas from the String, and assign the result back to the str variable. We then use the Long.parseLong method to parse the String as a long value, and assign it to a long variable called value.
