Video temp = new Video();
for(passCount = 0; passCount < videos.length ; passCount++){
minIndex = passCount;
for(placeCount = passCount + 1; placeCount < videos.length; placeCount++){
if((videos[placeCount].getVideoId()) < (videos[minIndex].getVideoId())){
minIndex = placeCount;
System.out.println(temp);
}
temp = videos[passCount];
System.out.println(temp);
videos[passCount] = videos[minIndex];
videos[minIndex] = temp;

}
