Let's quickly recap the key points in this section.
0:06
S… Speaker 1 (19- Summary)
Multi -threaded applications can do more in less time,
0:09
S… Speaker 1 (19- Summary)
but they're challenging to build.
0:10
S… Speaker 1 (19- Summary)
One of the problems in multi -threaded applications is a race condition,
0:14
S… Speaker 1 (19- Summary)
which happens when multiple threads try to modify an object concurrently.
0:19
S… Speaker 1 (19- Summary)
We may get wrong results or our application may crash.
0:22
S… Speaker 1 (19- Summary)
Another problem in multi -threaded applications is that a thread can change
0:26
S… Speaker 1 (19- Summary)
an object, but the change may not be visible to other threads due to caching.
0:31
S… Speaker 1 (19- Summary)
We talked about various strategies to prevent these problems.
0:34
S… Speaker 1 (19- Summary)
The first strategy was confinement,
0:36
S… Speaker 1 (19- Summary)
which means not sharing data across threads.
0:38
S… Speaker 1 (19- Summary)
We also talked about synchronization,
0:40
S… Speaker 1 (19- Summary)
which involves locking and makes your code run sequentially.
0:44
S… Speaker 1 (19- Summary)
So try to avoid it if you can.
0:46
S… Speaker 1 (19- Summary)
We also talked about atomic types.
0:49
S… Speaker 1 (19- Summary)
These types don't use locks.
0:50
S… Speaker 2 (19- Summary)
Instead,
0:51
S… Speaker 1 (19- Summary)
they use the compare and swap technique.
0:53
S… Speaker 1 (19- Summary)
They're great for implementing counters.
0:55
S… Speaker 1 (19- Summary)
We also talked about partitioning.
0:58
S… Speaker 1 (19- Summary)
Concurrent collections in Java use this technique to allow multiple threads
1:02
S… Speaker 1 (19- Summary)
access different segments or partitions concurrently.
1:06
S… Speaker 1 (19- Summary)
So that brings us to the end of this section.
1:08
S… Speaker 1 (19- Summary)
In the next section,
1:09
S… Speaker 1 (19- Summary)
we're going to talk about the newer higher level constructs for building concurrent
1:13
S… Speaker 1 (19- Summary)
applications in Java.
1:14
S… Speaker 1 (19- Summary)
So I will see you next.
