+title: swap in double-linked lists
+date: 07.05.2012 22:22

+
+Yesterday I had to implement [Selection Sort](http://en.wikipedia.org/wiki/Selection_sort)
+for double-linked lists and I had some trouble finding the correct solution
+when it comes to swapping two elements.
+
+But I finally figured out how to correctly swap the pointers and I'll drop the
+code here so others can use it (or even tell me about hidden bugs)
+
+I implemented it in Java, so see here:
