java very simple array list of classes

attached is a very simple java example where i want to gerate classses PreCut and then i want to store them in a Arraylist preCuts. after that i want just to access the data by system.outs. now the data is wrong i add precut and newprecut. but the data seems to be overwritten. output is : 5 6 7 8 5 6 7 8 should be 1 2 3 4 5 6 7 8 additonally i want to know the classic for loop for reading the data not the xxxx : xxx version. something like for (int i=0; i < [login to view URL]; i++) [login to view URL]() - -- all data for each class that is inside the arraylist.
