There is no guarantee that you will iterate over all your dict entries if you mutate it in your loop. From the docs: Iterating views while adding or deleting entries in the dictionary may raise a RuntimeError or fail to iterate over all entries. You could create an “enumerated” infinite loop similar to your initial … Read more
As per the javadoc for Scanner: When a scanner throws an InputMismatchException, the scanner will not pass the token that caused the exception, so that it may be retrieved or skipped via some other method. That means that if the next token is not an int, it throws the InputMismatchException, but the token stays there. … Read more
One line of code using Java 8: line = buffer.lines().collect(Collectors.joining());
Ok, so first off, let me say this: Use while(true), as it gives the most semantic meaning. You need to parse for (;;) as it’s not something you see often. With that said, let’s analyze: Opcodes The code while(true) { break; } echo “hi!”; Compiles down to the opcodes: 0: JMPZ(true, 3) 1: BRK(1, 3) … Read more
There is no difference in bytecode between while(true) and for(;;) but I prefer while(true) since it is less confusing (especially for someone new to Java). You can check it with this code example void test1(){ for (;;){ System.out.println(“hello”); } } void test2(){ while(true){ System.out.println(“world”); } } When you use command javap -c ClassWithThoseMethods you will … Read more
You can also use a while loop: while (true) { //your code }

You can try wrapping that code in a try/except block, because keyboard interrupts are just exceptions: try: while True: IDs2=UpdatePoints(value,IDs2) time.sleep(10) except KeyboardInterrupt: print(‘interrupted!’) Then you can exit the loop with CTRL-C.
To avoid the infinity loop simply use a WaitHandle. To let the process be exited from the outer world use a EventWaitHandle with a unique string. Below is an example. If you start it the first time, it simple prints out a message every 10 seconds. If you start in the mean time a second … Read more
The key to answering this is deferred execution. When you do this items = items.Select(item => items.First(i => i == item)); you do not iterate the items array passed into the method. Instead, you assign it a new IEnumerable<int>, which references itself back, and starts iterating only when the caller starts enumerating the results. That … Read more
