In java, int
type is a 32-bit signed value, of which the maximum value is 2147483647(2^31-1).
Obviously your value "715534907077099" is much bigger than Integer.MAX_VALUE. If it's still less than Long.MAX_VALUE, int n = Long.parseLong(strValue)
will work.
But if you don't want to have a up limit, use BigInteger
instead:
BigInteger bi = new BigInteger(Integer.toString(kol[0]) + Integer.toString(kol[1]) +
Integer.toString (kol[2]));
System.out.println(bi);
