multithreading - Java: Logging for multiple Threads with Log4j2 -


let's have 3 classes a, b , c working in separate threads (ta, tb, , tc) , of them have own instance of logger.

now got mess in ouput because there no order in loggings of 3 classes. there possiblity sort loggings in order of appearance?

for example:

class {     public static final logger logger = loggerfactory.getlogger(a.class);      public void start() {         logger.info("testa");         logger.info("testa");         logger.info("testa");     } }  class b {     public static final logger logger = loggerfactory.getlogger(b.class);      public void start() {         logger.info("testb");         logger.info("testb");         logger.info("testb");     } }  class {     public static final logger logger = loggerfactory.getlogger(c.class);      public void start() {         logger.info("testc");         logger.info("testc");         logger.info("testc");     } }

output:

testa testa testb testb testa testc testc testb testc

what want is:

testa testa testa testb testb testb testc testc testc

since logging definition time-based, doesn't make sense try think achieve (well, without additional work of course).

what can add thread id logging layout. can use other tools (e.g. grep) isolate logging specific threads wish see, or sort log thread id give logs each thread sequentially.

arrays - What causes a java.lang.ArrayIndexOutOfBoundsException and how do I prevent it? -

what arrayindexoutofboundsexception mean , how rid of it? here code sample triggers exception: string[] name = {"tom", "dick", "harry"}; for(int = 0; i<=name.length; i++) { system.out.print(name[i] +'\n'); } your first port of call should documentation explains reasonably clearly: thrown indicate array has been accessed illegal index. index either negative or greater or equal size of array. so example: int[] array = new int[5]; int boom = array[10]; // throws exception as how avoid it... um, don't that. careful array indexes. one problem people run thinking arrays 1-indexed, e.g. int[] array = new int[5]; // ... populate array here ... (int index = 1; index <= array.length; index++) { system.out.println(array[index]); } that miss out first element (index 0) , throw exception when index 5. valid indexes here 0-4 inclusive. correct, idiomatic for statement here be: for (int index = 0; index <...
