Thread: Help with arrays

Hi there, I am fairly new to Java and i need your help! I do not understand what is going on, im trying to make an array and on one of the lines it says " 'i' cannot be resolved in the variable ".

Here is my code:

public class Arrays {
	public static void main(String[] args) {
 
		int value = 7;
 
		int[] values;
		values = new int [3];
 
		System.out.println(values[0]);
 
		values[0] = 10;
		values[1] = 20;
		values[2] = 30;
 
		System.out.println(values[0]);
		System.out.println(values[1]);
		System.out.println(values[2]);
 
		for(int i = 0; i < values.length; i++); {
			System.out.println(values[i]);
		}
	}
}

im getting the error with the i in this line of code System.out.println(values[i]);

Thanks in advance!

also i am using a program called Eclipse - Kepler

Your problem lies here.

for(int i = 0; i < values.length; i++); {

Look very carefully.

Might I say, well done on posting correctly the first time too.

Thanks! What i did was i took int out of for and put it in its own row like this:

int i=0;
for(i=0; i<values.length; i++); {

It worked, but is that what i should do in the future?

Nevermind, what i did is now canceling out int value = 7;

i really suck at this.

No, that's not it. It's a syntax error in your original code. You have incorrectly placed a semicolon after the closing parentheses in your 'for loop'. Remember that a semicolon indicates the end of a statement.

OH WOW I'm sorry about that, this is like my 3rd day into Java, i still dont really know where everything goes. Thanks dude!

That's cool, you'll probably do more stuff like this and stare at it for ages. Your IDE Eclipse is good at pointing out stuff most of the time. Now you're aware of it, you'll be very vigilant.

Stick at it, it's lots of fun and rewarding.

Yes of course cheers Junky
