Why I can't convert a String to int?

I'm very new in Java. I've a problem. I have the String currentTime with a value of the current time like this: "2204201810". I want to convert this String to an Integer. The Error is:

Caused by: java.lang.NumberFormatException: For input string: "2204201804"

But I don't know why Java can't convert it! I mean the String contains just Numbers not more.

Here is my code:

GregorianCalendar now = new GregorianCalendar();
DateFormat df = DateFormat.getDateInstance(DateFormat.SHORT);

df = DateFormat.getDateTimeInstance(DateFormat.SHORT, DateFormat.SHORT);
String currentTime = df.format(now.getTime());

currentTime = currentTime.replace(".", "");
currentTime = currentTime.replace(" ", "");
currentTime = currentTime.replace(":", "");
try {
    int currentTimeInt = Integer.valueOf(currentTime);
} catch (NumberFormatException ex) {
    //Error
}

The value you are trying to convert to int (2204201804) exceeds the maximum integer capacity, which is 2147483647 in Java. Try using long instead. Or maybe even BigInteger, depending on your needs.
