Hi,

i'm trying to access and print the days of the week with a while loop::

String daysOfWeek []= {"Monday","Tuesday","Wednesday","Thursday","Friday","Saturday","Sunday"};
		while( 1 to daysOfWeek.lentgh)
		{
			System.out.println(daysOfWeek);
		}

can anyone help me on how should be the condition of the while loop??
tnx...

for(String s : daysOfWeek)
	System.out.println(s);

this is called the enhanced for loop or for-each loop, coz it assigns each element in the array to s on each iteration..you could do it using a while loop like this..

int i = 0;
while(i < daysOfWeek.length)
{
	System.out.println(daysOfWeek[i]);
	i++;
}

first declare the counter variable i to 0 coz you're gonna be printing from the start of the array, arrays start from zero up to length-1, so you will be iterating till length-1

That almost looks like you've used Visual Basic before. But yes, Java (and C/C++/C#) are all of the same syntax, and they are all a bit more symbol oriented than VB.

It's almost more like a symbolic math comparison -- i < daysOfWeek.length -- i will be your control variable, whose only purpose is to count up and help us access the array in order. So...that translates to while i is less than the length of the daysOfWeek array.

int i = 0;

while (i < daysOfWeek.length)
{
    System.out.println(daysOfWeek[i]);
    i++; // simply increase the value of i by 1
}

Hope this clears it up!
