Trying to sort an array of objects

[superhaNds]

Hey, I have an array of objects and I want to sort them by their priority. Priority is from 1 to 5 and I use the same approach as a bubble sort since it is the same concept

code:

public void sortTasksByPriority() {
	for (int k = 0; k < tasks.length - 1; k++) {
	    boolean isSorted = true;
	    for (int j = 1; j < tasks.length - 1; j++) {
		if ((tasks[j].getPriority() < tasks[j - 1].getPriority()) && (tasks[j] != null 
			&& tasks[j - 1] != null)) {
		    Task tempTask = tasks[j];
		    tasks[j] = tasks[j - 1];
		    tasks[j - 1] = tempTask;
		    isSorted = false;
		}
		    
	    }
	    if (isSorted) {
		break;
	    }
	}
    }

getPriority() returns an integer from 1 to 5.
Can it be done this way? point me to any logic errors and inform me of a better way to accomplish this. :)

If task j-1 and/or task j can be null, better test that before you ask for their priority, i.e.:

		if ((task[j-1] != null && task[j] != null && task[j].getPriority() < tasks[j - 1].getPriority()) {

kind regards,
