Stack is a LIFO (last in first out) data structure. The associated link to wikipedia contains detailed description and examples. Queue is a FIFO (first in first out) data structure. The associated link to wikipedia contains detailed description and examples.
The following should do the trick: Log.d(“myapp”, Log.getStackTraceString(new Exception())); Note that …x more at the end does not cut off any information from the stack trace: (This indicates) that the remainder of the stack trace for this exception matches the indicated number of frames from the bottom of the stack trace of the exception that … Read more
Most of you are wrong. If you want to close existing activity stack regardless of what’s in there and create new root, correct set of flags is the following: intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK | Intent.FLAG_ACTIVITY_CLEAR_TASK); From the doc: public static final int FLAG_ACTIVITY_CLEAR_TASK Added in API level 11 If set in an Intent passed to Context.startActivity(), this flag … Read more
Hmm… it works for me and with far less than 999MB of stack: > java -Xss4m Test 0 (Windows JDK 7, build 17.0-b05 client VM, and Linux JDK 6 – same version information as you posted)
Position the outer div however you want, then position the inner divs using absolute. They’ll all stack up. .inner { position: absolute; } <div class=”outer”> <div class=”inner”>1</div> <div class=”inner”>2</div> <div class=”inner”>3</div> <div class=”inner”>4</div> </div>
Version A (efficient push): push: enqueue in queue1 pop: while size of queue1 is bigger than 1, pipe dequeued items from queue1 into queue2 dequeue and return the last item of queue1, then switch the names of queue1 and queue2 Version B (efficient pop): push: enqueue in queue2 enqueue all items of queue1 in queue2, … Read more
No, braces do not act as a stack frame. In C, braces only denote a naming scope, but nothing gets destroyed nor is anything popped off the stack when control passes out of it. As a programmer writing code, you can often think of it as if it is a stack frame. The identifiers declared … Read more
A similar question was asked, but it didn’t ask about statics. Summary of what static, heap, and stack memory are: A static variable is basically a global variable, even if you cannot access it globally. Usually there is an address for it that is in the executable itself. There is only one copy for the … Read more
Stack unwinding is usually talked about in connection with exception handling. Here’s an example: void func( int x ) { char* pleak = new char[1024]; // might be lost => memory leak std::string s( “hello world” ); // will be properly destructed if ( x ) throw std::runtime_error( “boom” ); delete [] pleak; // will … Read more
For one thing, it’s more sensible in terms of inheritance. The fact that Stack extends Vector is really strange, in my view. Early in Java, inheritance was overused IMO – Properties being another example. For me, the crucial word in the docs you quoted is consistent. Deque exposes a set of operations which is all … Read more
