try this way Intent i = new Intent(MainActivity.this, Main2Activity.class); startActivity(i); EDIT: I wanted to add a bit of an explanation to help Hi MRAK, First things first, you do NOT need to create an onClick listener. Remove all of that completely. Android studio is a beast and automatically does that for you using the XML … Read more
num is decreasing as it is /10 each time, and the loop exits when num is 0. armNum is potentially increasing each time it goes through the loop. So unless armNum is 0, it will be false. solved confused with int Assignments in Java [closed]
You can change the way Oracle sorts data by changing the NLS_SORT and NLS_COMP parameter for your session. If you want to retrieve say french data, you can use the following: ALTER SESSION SET nls_comp = Linguistic; ALTER SESSION SET nls_sort = XFrench_AI; select * from my_table where language_code=”fr” order by some_column; Consequently if you … Read more
I am assuming that have got a string, for example 2016-01-25, and that you want a string containing the start of the day in the JVM’s default time zone (it wasn’t clear from the question). I first define a formatter for the format that you want (it’s ISO 8601): private static DateTimeFormatter formatter = DateTimeFormatter.ofPattern(“uuuu-MM-dd’T’HH:mm:ss.SSSxx”); … Read more
put your selector under res/drawable and use label.setTextColor(getResources().getColorStateList(R.drawable.text_selector)); don’t forget to set android:clickable=”true” in the declaration of your TextView in the layout 3 solved How to set the text_selector at the run time
I would look at these lines here: double xPoint[][][] = new double[value][fps][64]; //… for (int j = 0; j < (44100 / fps); j += ((44100 / fps) / 64)) { xPoint[counter][i][j] = magnitude[counter][i][j]; Note that the inputted fps is 30, so ((44100 / 30) / 64)) = 22.96875 (or 22 as an int). So … Read more
Here’s what I’ve got, took me a while but this will do what I was looking for: it takes each combination of the arrays (t1, t2, t3, t4) and adds their elements and returns whatever combinatorial you choose for n, (in this example i left it as 3). If there’s any more optimizations you can … Read more
Use CASE expressions to count each column. SELECT CASE WHEN Column1 IS NOT NULL THEN 1 ELSE 0 END + CASE WHEN Column2 IS NOT NULL THEN 1 ELSE 0 END — repeat for all columns AS NumberOfNonNullColumns FROM MyTable 3 solved Count the number of existing values in a field in a record [closed]
replace percent to counter and percent2 to counter2. solved My condition for progress is invalid [closed]
You shouldn’t be using ndataServerReader.ready(). Your do/while loop (which should almost certainly just be a while loop) appears to assume that ndataServerReader.ready() indicates there’s more data to be read, which is not what it’s for. The Javadoc for Reader describes the ready() method as: Tells whether this stream is ready to be read. Returns: True … Read more
you’re not looking for an if statement are you? if(error.Colour() == /*insert value to check here*/) { calculate.setKey(key); calculate.setQuantity(QuantityInt); double cost = calculate.calculateBill(); information.append(“\n\nTotal cost: £” + pounds.format(cost)); } 5 solved java, “do this if passes then do this” [closed]
You probably have a variable(FileReader,…) open, remember that you need to close them close() if its a gui application call JFrame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); 7 solved Java application closed but still the dist process running [closed]
You could build something along this pseudo code: for y=0 to 3 * ysize for x=0 to 3 * xsize if x even and y even print + if x even and y odd print | if x odd and y even print — if x odd and y odd print space space I don’t … Read more
You need the basic date comparion between current date and input date given by the user right? Do it like this: Calendar userDate = Calendar.getInstance(); Calendar currentDate = Calendar.getInstance(); userDate.setTime(inputDate);//here inputDate is date given by the user. if(!userDate.before(currentDate)) { // user date is after current date(today). } else { // user date is before current … Read more
So, the first line is a while-loop it keeps evaluating the statements in between the {} brackets if the condition x<4 is fulfilled. while ( x < 4 ) { Let’s assume x = 0 x<4 is a true statement so we enter the brackets: System.out.print(“a”); will print ‘a’ the next line if ( x … Read more
