ok, i'm having a problem with a method...

class one..

    
public class Inovate
{
 
public String ReverseIt(String word)
 
{
char temp;
char [] array = new char [word.length()];
int I = 0, J = array.length - 1;
 
if (word.length() == 1)
return word;
 
for(int i = 0; i<word.length(); i ++)
{
 
array[i] = word.charAt(i);
}
 
if (I <= J)
{
temp = array[I];
array[I] = array[J];
array[J] = temp;
 
I ++;
J --;
}
 
ReverseIt(word);
 
return word;
 
}
 
}

Now here is my main....

    
public class InovateImple
{
 
public static void main (String [] arg)
{
 
String a = "hello";
 
System.out.println(a);
 
Inovate.ReverseIt(a);
 
System.out.println(a);
 
}
}

ok, so the ReverseIt() method is giving me some trouble, and i dont know why...

please help, thank you

ReverseIt is an instance method (not static), so you need to create an instance of Inovate in order to call the method...

Inovate in = new Inovate();
in.ReverseIt(a);

ok so if i wanted to call the method like this....

ReverseIt(a);


i would have to do this?

public static class Inovate
{
public static String ReverseIt()
{}
}

like that huh?

but i can't believe i missed that lol, thx for the help

Well, a top-level class can't be static, but a method defined in that class can be static. In that case, you could call the method using the class name...

Inovate.ReverseIt();

If ReverseIt were defined within scope (e.g., in the same class as main), then you could call the method without qualification -- that is, without the class name. But it looks like you have two separate classes here, so the compiler won't know what "ReverseIt" means unless you specify the class with "Inovate.ReverseIt".

k, thx a lot, think i can handle it from here
