Splitting String and put it on int array

Question

I have to input a string with numbers ex: 1,2,3,4,5. That\'s a sample of the input, then I have to put that in an array of INT so I can sort it but is not working the way it

Answer 1

Let's consider that you have input as "1,2,3,4".

That means the length of the input is 7. So now you write the size = 7/2 = 3.5. But as size is an int, it will be rounded off to 3. In short, you are losing 1 value.

If you rewrite the code as below it should work:

String input;
int length, count, size;
Scanner keyboard = new Scanner(System.in);
input = keyboard.next();
length = input.length();

String strarray[] = input.split(",");
int intarray[] = new int[strarray.length];

for (count = 0; count < intarray.length ; count++) {
    intarray[count] = Integer.parseInt(strarray[count]);
}

for (int s : intarray) {
    System.out.println(s);
}
