import java.util.*;
int n=787;
int l=n.length();
When I am trying to compile this I am getting the error as
int cannot be dereferenced.
And I understood that 'int' are primitives and '.' operator cannot be used with that. Now my question is how do I find the length of an an integer.
Thanks in Advance,
Ambika

Just what do you mean by the "length" of an integer? An integer takes up 32 bits (usually). There really is no length. Now if you are talking about the number of characters in the string "787", now that's a differnt story since here we are taking about strings, not ints. For instance:
int numberOfChar787 = String.valueOf(787).length();
This yields a result of 3, but again, this is a measure of a length of the String "787".
As petes1234 said
class intlength
{
public static void main(String args[])
{
int numberOfChar787 = String.valueOf(787).length();
System.out.println(numberOfChar787);
}
}
you can also use variable in '787'...
class intlength
{
public static void main(String args[])
{
int i = 4589;
int numberOfChar787 = String.valueOf(i).length();
System.out.println(numberOfChar787);
}
}
