Integer.parseInt() throws "For input string: XXX"

I am reading high volume of records from a csv file. one of the column is amount and it has 2 decimal places. So I wanted to parse it to integer form but it hit error when come to this as below :

int trxnAmt = Integer.parseInt("002428859600");

Suppose it will be 2428859600 right ?

but it throws me error > java.lang.NumberFormatException: For input string: "002428859600"

I tried to use :

long a = Long.parseLong("002428859600");

it worked fine for me .

I still cannot find out what's going on. Is the number too big ?

You are getting the java.lang.NumberFormatException: For input string: "002428859600" because, the number 002428859600 cannot be represented as a 32-bit integer (type int). It can be represented as a 64-bit integer (type long). long literals in Java end with an "L": 002428859600L

Yes, you are passing out of the range integer value to parseInt method.

The int data type is a 32-bit signed two's complement integer. It has a minimum value of -2,147,483,648 and a maximum value of 2,147,483,647 (inclusive).

Try long or other suitable options.

Is the number too big?

Yes. An int is 4 bytes, so the biggest number that will fit into an int is 24*8-1-1 = 231-1 = 2147483647 (4*8-1 because 1 bit is required for sign).

You should make sure that your input really is an integer (i.e. "16"), or if it's out of Integer range, then use Double.parseDouble() or Long.parseLong()

Yes 2428859600 is a long number. try to assign it a int and you'd get a compiler error :

int i = 2428859600;  // error as 2428859600 is clearly outta int range(2,147,483,647)
long l = 2428859600L; //no error
