Someone asked me to make a "Bubble Sort" algorithm. So...

WhatsAbubbleSort.java

import java.util.*;
import java.lang.*;
import java.io.*;

class WhatsAbubbleSort {
	
	public static void main (String[] args) throws java.lang.Exception {
		
		final int[] unsorted = new int[] { 23, 25, 7, 13, 94, 11 };
		
		WhatsAbubbleSort sorter = new WhatsAbubblerSort();
		final int[] sorted = sorter.runBubbleSort(unsorted);
		
		WhatsAbubbleSort.printArray(sorted);
	}
	
	int[] runBubbleSort(int[] numbers) {
		
		final int[] output = numbers.clone();
		while(!bubbleSort(output));
		return output;
		
	}
	
	public static void printArray(int[] numbers) {
		
		for (int number : numbers) {
			System.out.println(String.valueOf(number));
		}
		
	}
	
	private boolean bubbleSort (int[] numbers) {
		
		final int limit = numbers.length;
		
		for (int i = 0; i < limit; i++) {
			if ((i+1 < limit) && (isMoveRequired(numbers[i], numbers[i+1]))) {
				int temp = numbers[i+1];
				numbers[i+1] = numbers[i];
				numbers[i] = temp;
				return false;
			}
		}
		return true;
	}
	
	private boolean isMoveRequired(int i1, int i2) {
		return i2 > i1;
	}
	
}
