Question

Here is the code I am working with in a main method:

String numbers = "12345678900";
long upc = Integer.parseInt(numbers);
System.out.println(upc);

gives me:

Exception in thread "main" java.lang.NumberFormatException: For input string: "12345678900"
at java.lang.NumberFormatException.forInputString...
at java.lang.Integer.parseInt....
at java.lang.Integer.parseInt...
at testRun.main...

I cannot use a double, they need to be stored as values without a decimal. I am trying to get the string of numbers from a string into a variable that holds numbers (no decimals)

Answer 1

To parse a long, use Long.parseLong, not Integer.parseInt. That way, you get access to the full range of long values (whereas with parseInt, you only get the rather more restricted range of int values).
