Programming Question? - index of /private -dsc

This program is an independent adjustment of the list that begins with 10 numbers, and if a number is called, moves the list .. the teacher wrote the following code, and I can not imagine what they do with the first 2 classes, or loop. There are customers, but it goes .. any help is appreciated.
public class SelfAdjustingList (
selfAdjust private int [];
Public SelfAdjustingList (arraySize int)
(
)
placeNum public void (int, int num)
(
)
public void findAndMove (int searchNum)
(
int index = findNum (searchNum);
(moveNum index);
)

private void moveNum (int pos)
(
int temp = selfAdjust [pos];

/ / Loop
selfAdjust [selfAdjust.length - 1] = temp;
)
findNum public int (int searchNum)
(
boolean found = false;
posOfSearchNum int i = 0;
while (found)
(
if (searchNum == selfAdjust [posOfSearchNum])
(
posOfSearchNum return;
)
other
posOfSearchNum + +;
)
return -1;
)

public String toString ()
(
/ / Always this
