Thread: How to remove the last comma

Right now my output is like this:
2, 4, 6, 8, 10,

What I want:
2, 4, 6, 8, 10

	            PrintWriter fout = new PrintWriter(new BufferedWriter(new FileWriter("numbers.dat"))); 
	            for(int i = start; i <= 100; i = i + 2)    { 
	                fout.print(i+","); 
	            }

count=0;
for ..{
if (count<4){
fout.print(i+",");count++;}
else {fout.print(i);count=0;} 
}

try this

Above code will only work for given set of numbers. What if there are only 3 numbers? 20 Numbers? 10000 numbers?

It is easier to determine when you are at the first number than the last number. So print a comma before each number except the first.

Here i will show you the pseudocode.

PRINT array[FIRST_INDEX];
LOOP I=1 TO array.LENGTH STEP 1
        PRINT "'";
        PRINT array[I];
END LOOP
