I’m trying to make a program that consists of an array of 10 integers which all has a random value, so far so good.
However, now I need to sort them in order from lowest to highest value and then print it onto the screen, how would I go about doing so?
(Sorry for having so much code for a program that small, I ain’t that good with loops, just started working with Java)
public static void main(String args[]) { int [] array = new int[10]; array[0] = ((int)(Math.random()*100+1)); array[1] = ((int)(Math.random()*100+1)); array[2] = ((int)(Math.random()*100+1)); array[3] = ((int)(Math.random()*100+1)); array[4] = ((int)(Math.random()*100+1)); array[5] = ((int)(Math.random()*100+1)); array[6] = ((int)(Math.random()*100+1)); array[7] = ((int)(Math.random()*100+1)); array[8] = ((int)(Math.random()*100+1)); array[9] = ((int)(Math.random()*100+1)); System.out.println(array[0] +" " + array[1] +" " + array[2] +" " + array[3] +" " + array[4] +" " + array[5]+" " + array[6]+" " + array[7]+" " + array[8]+" " + array[9] ); }

Loops are also very useful to learn about, esp When using arrays,
int[] array = new int[10]; Random rand = new Random(); for (int i = 0; i < array.length; i++) array[i] = rand.nextInt(100) + 1; Arrays.sort(array); System.out.println(Arrays.toString(array)); // in reverse order for (int i = array.length - 1; i >= 0; i--) System.out.print(array[i] + " "); System.out.println();
