How correctly parse string value in JAVA from text in sum?

i have a problem with one task in Java. I have text file with these numbers –

input : 000000004599
000000001000

And the result should be –
output: 45.99
10.00
sum of two varriables – 5599 (yes,without "dot")

I only have guesses that it is necessary to remove numbers from the beginning through the array.
Example :
if (arr[i] = 0 && arr[i + 1] = 0) {
…
}

I’m sure there is another logical solution

>Solution :

You can simply use Integer.parseInt.

Integer.parseInt("000000004599") + Integer.parseInt("000000001000"); // 5599
