Thread: Sorting an Array

{
	static int TestArray[] = {5,10,8,16,20,17,18,11,1,3,13,19};
 
	public static void main(String Args[])
	{
		for (int count=0; count<TestArray.length;count++)
		{
			for (int count2=1;count2<TestArray.length;count2++)
			{
				if (TestArray[count] > TestArray[count2])
				{
					int temp = TestArray[count];
					TestArray[count]=TestArray[count2];
					TestArray[count2]=temp;
				}
			}
		}
		System.out.print(TestArray[0]+ " " +TestArray[1]+ " " +TestArray[2]+ " " +TestArray[3]+ " " +TestArray[4]+ " " +TestArray[5]);
	}
}

Silly mistake really, got it sorted.

	public static void main(String Args[])
	{
		for (int count=0; count<TestArray.length;count++)
		{
			for (int count2=count+1;count2<TestArray.length;count2++)
			{
				if (TestArray[count] > TestArray[count2])
				{
					int temp = TestArray[count];
					TestArray[count]=TestArray[count2];
					TestArray[count2]=temp;
				}
			}
		}
