So we have this sample, [code lang=”java”] class SyncMe { synchronized void doFoo1() { int x = 0; } void doFoo2() { synchronized (this)…

Todays lesson is: What javac does with following methods, when compiled. Assumptions: Iterating over ArrayList vs. List generates optimized code, not creating Iterator (i.e. would optimize memory usage using RandomAccessList API), but using int index Itearating over Object[] is faster than List/ArrayList foreach loop for Object[] is as tight code as manual iteration [code lang=”java”]…
