Implement a simple Bubble Sort algorithm in java

public class BubbleSort {
    public static void main(String[] args) {
        int[] arr = {64, 34, 25, 12, 22, 11, 90};
        for(int i = 0; i < arr.length - 1; i++) {
            for(int j = 0; j < arr.length - i - 1; j++) {
                if(arr[j] > arr[j + 1]) {
                    int temp = arr[j];
                    arr[j] = arr[j + 1];
                    arr[j + 1] = temp;
                }
            }
        }
        System.out.println("Sorted array: ");
        for(int num : arr) {
            System.out.print(num + " ");
        }
    }
}
