round a floating-point number to the next integer value in java

Question

how can i round up a floating point number to the next integer value in Java? Suppose

2.1 -->3

3.001 -->4

4.5 -

Answer 1

If it helps someone, here's how I get this working:

int arraySize = 3;
int pageSize = 10;
int pagesQty = (int) Math.ceil(arraySize / (float) pageSize);

System.out.println(pagesQty);

//Displays 1

Divisor must be a float in order to work properly.
