Static Method Help Please?

You again...

You know you could actually try this one out.

Just add in a a main method, and I think you're set to compile and run. Tsk tsk tsk...

as so...

public class crap

{

public static String sayAgain( String word, int num )

{

int k;

String result = "";

for ( k = 0 ; k < num ; k++ )

{

result += word;

result += " ";

}

return result;

}

public static void main(String[] args)

{

String str = "ha";

System.out.println( sayAgain( sayAgain( str, 2 ), 3 ) );

}

}

First method ran is the inner one (( sayAgain( str, 2 )), then it goes outward....

Basically the string is ran through a for loop than runs under whatever int num is (the 1st time it runs only 2 times, right?)

So it'll print the string 2 times, once for everytime the for loop is running.

Then the second method sayAgain( sayAgain( str, 2 ),3

is run. The for loops runs 3 times now, printing the result of the first method 3 times, 3 times 2 = 6.

6 instances of the string "ha".

I probably left out some things ... ON PURPOSE. Go ask a classmate about these things, or maybe your teacher/ a tutor.

GL in class!!! Thanks for letting me practice my knowledge.

static is a 'modifier'. We use modifiers all the time in English. We don't even think about them: I live in a house. (Most of us do). I live in a bird house. (bird is a modifier that immediately tells you that I'm a bit odd...) Same thing with static: foo is a method of class bar. foo is a static method of class bar. If foo is a method of bar, then I would assume to call foo, I would need to create an instance of bar first: bar b = new bar(); b.foo(); If foo is a *static* method of bar, then I would know that would *not* need to create an instance of bar: bar.foo(); HTH
