Cannot cast java util date to java lang string

help java.lang.String cannot be cast to java.util.Date I report with dates

The mistake tells you that you can’t turn a string into a date type object Surely you have set your parameter as Date

This can also be done from the designer without editing the xml of the *.jrxml Recommendation You can leave your parameter like Date and you textField if you have it as a string To send it directly from java and format it from the report

filtroFecha.put("Fecha1", fechaInicio)); filtroFecha.put("Fecha2", fechaFin));

java.lang.NoSuchMethodError in java library from Kotlin on Android 5

After the update Android Gradle Plugin before 4+ I’m in trouble again. After the analysis, the following observed:All my dependence was artifacts— they have no metadata.Android Studio collects apk not as it does in the console (she adds the API of the device during the assembly process through the button run for acceleration) — the device android 7+ Only because the target is working. API was 24+ As a result, no desugaring was produced for static methods in interfaces (as was no longer necessary because the devices with such an android support the function).Java worked only through another dehugaering and bonding mechanism. Android Gradle Plugin before 4+)Local dependencies: I assume this option only worked because gradle No local dependence.Decision:I added the right metadata to addictions.pom.xml or .module files that clearly mark the binary files, and now R8 Makes dehugaering right, and it works right.P. S. Also, if, for some reason, it is not possible to add metadata, all local dependence can be tightened.

How can I delete latest 2 binlog files from RDS MYSQL Aurora
SQL, Database Testing • mysql aws aurora mysqlbinlog • • Analeea

«I want to have binlog identical to the master.» Why would you want this? The binlogs are already not identical between these two instances, even besides the last two, because the filenames and sizes are different. Binlogs start new files if FLUSH LOGS is run, or if MySQL Server restarts, or the file reaches the max binlog size. The number of files and their sizes are bound to be out of sync between the source instance and its replicas. I would guess in this case that restoring the snapshot caused two restarts. It’s not a problem for binlog files to have different sizes. As long as they contain the same changes, they can be stored in few files or many files, and they don’t have to be the same. To apply changes in binlogs, you must have a contiguous set of changes since the last snapshot. If you were to purge the last two files, you could never use the binlogs for replication or point-in-time recovery, at least not past mysql-bin-changelog.603813. Purging the binlog files older than the latest snapshot is common and recommended, but not the newest binlog files. In fact, PURGE BINARY LOGS will never remove the latest binlog file, because the MySQL Server is still using it. One solution for you is to set the expire_logs_days in the parameter group to a modest value such as 2 or 3, then wait that number of days for the current set of binlogs to expire. After that, the small binlog files will be gone.

Split a date into two part
Software Programming • javascript php mysql jquery mysqli • • Alberto

I would store with 2 fields.data, field date even (or int counting number of days of a default date).periodo Field int of 1 byte alone, or enum being:1 == sync, corrected by elderman ==2 == sync, corrected by elderman ==3 = both periodsThis simplifies the problem.Checking if the date is free.To test date availability, just do this select:SELECT periodo WHERE data=$data AND ( periodo=$periodo OR periodo=3 OR $periodo=3 ); periodo=$periodo means conflict, if asked morning and already has morning, or if asked late and already has afternoonperiodo=3 means conflict, because if you already have one occupying all day, you have no way to schedule anything else on that date.$periodo=3 means conflict, because if you are trying to schedule all day, any existing schedule prevents scheduling.If query above do not return any registration, you can make a new schedule on the date $data for the period $periodo.If, on the other hand, it returns records, it does not stop the new scheduling as it will have a conflict.

Java error «java.util.ConcurrentModificationException»
Software Programming • java exc languageeptions • • Oba22

This is because you are trying to add elements to your list by which you have created the iterator while you are traveling through it. Through this line:datosTrayectos.add(new Trayecto()); Therefore, the iterator, when detecting that the list has been modified, cannot guarantee that it is by all data correctly. That’s why he’s giving you the mistake, since he can’t secure the integrity of the data.I recommend that you create another list and use this list to save the new data.List nuevosTrayectos = new ArrayList(); Once all iterations are finished you can use the method https://docs.oracle.com/javase/7/docs/api/java/util/ArrayList.html#addAll(java.util.Collection) to combine both ArrayList:datosTrayectos.addAll(nuevosTrayectos);

How to run multiple FOR at the same time
Software Programming • java for • • Alberto

You can create 4 Threads with Runnable. Note that No will be exactly at the same time, but one will not need to wait for the other, for example:new Thread(new Runnable() < @Override public void run() < for(int i = for1; i < for2; i++) < System.out.println(i + " de " + busca + "\r"); >> >).start(); new Thread(new Runnable() < @Override public void run() < for(int i = for2; i < for3; i++) < System.out.println(i + " de " + busca + "\r"); >> >).start(); However if you really need it to be at the same time, you will have to create all events within a single loop and use a Boolean variable to check if at least one of the conditions entered oneIF:bool testIfs = false; int increment1 = 0; int increment2 = 0; while (true) < if (increment1 < for2) < //Se entrar na condição então não irá lançar o break testIfs = true; System.out.println(increment1 + " de " + busca + "\r"); increment1++; >if (increment2 < for3) < //Se entrar na condição então não irá lançar o break testIfs = true; System.out.println(increment2 + " de " + busca + "\r"); increment2++; >if (testIfs == false) < //Se o loop não entrou em nenhuma das if então é executado o break pra poder parar o loop break; >//Se não houve break então testIfs volta a ser false pra testar novamente o loop testIfs = false; > In this example, I just added a two conditions to understand, but you can add several «ifs».

I’ve been looking at your code and not if the error was time to write the question or actually it’s coded so` activity main ImageView profileView = (ImageView)headerLayout.findViewById(R.id.profile_image);` The error message appearing on the console is about the call of the findViewById method.Caused by: java.lang.NullPointerException: Attempt to invoke virtual method ‘android.view.View android.app.Activity.findViewById(int)’ on a null object reference at sptour.hotmail.com.Main6Activity.onCreate(Main6Activity.java:69) From a little look at that, something says there.
