This line: if (mat1[i][j] == mat2[i][j]) is testing to see if the corresponding elements of the 2 matrices have the same value. Looking at it in context: if(mat1[i][j] == mat2[i][j]){ b = b & true; } else{ b = b &false; } is a rather cumbersome way of saying this: if(mat1[i][j] != mat2[i][j]){ b = … Read more
Thanks to everyone who attempted to help. The bug apparently lies in TestNG. How to make sure TestNG runs methods on test classes in succession instead of interleaved? solved Jenkins mixing up tests from different Java classes
… why do almost the all method implementations return only -1, 0, 1? I can’t speak for other programmers, but I typically do this because it is simpler and more convenient to do that in most case. And most important, it is correct. I imagine that you are thinking along the lines of doing this: … Read more
I don’t think your for loop is doing what you want it to do. Like, at all. temps[i] = in.nextInt(); // This is sensible enough closest = Math.abs(temps[0]); // Every time your loop runs, the closest value to 0 is… the absolute value of the first int in the array? //System.err.println(temps[i]); if (closest > 0) … Read more
I tried to explain it (see the code i used comments) public static void main(String[] args) { int[][] magic = new int[7][5]; //<<Create a new Bidimentional Array odd(magic); } public static void odd(int[][] magic) { int N = magic.length; //it will take the length in position 0 from array well the 7 [7][5] so if … Read more
I’m guessing it’s the line Program.setInventorie(c1);. You need to create an instance of the Program class and call setInventorie() on that. setInventorie() is not a static method. e.g.: Program myProgram = new Program(); myProgram.setInventorie(c1); 7 solved Arraylist for subclasses [duplicate]

I don’t understand as well what do you mean by “custom list”. But in your code, it seems you want to retrieve only the first and the last integer from the List. If you want to perform only this two operations, a Queue would be better than an ArrayList in term of performance. Obviously, if … Read more
From the picture you uploaded (please copy/paste the log here!), you have a missing column in your database, called insurance_dead_line. So you probably didn’t configure it your Liquibase changelog – did you create it with JHipster? Did you run mvn liquibase:diff? Or did you write your changelog manually? You have many options: I don’t know … Read more
In this case it’s highly recommended if you add some code that you tried! You have to follow the steps given below. Hope you would better understand if I don’t give you the code. 1) Create a scanner 2) Open the file 3) read the line 4) assign the read line into a string variable … Read more
You can use java Calendar class to get everything about Time and Date: System.out.println(“0″+Calendar.getInstance().get(Calendar.DAY_OF_MONTH)+”0” + (Calendar.getInstance().get(Calendar.MONTH)+1) +”0″+ Calendar.getInstance().get(Calendar.YEAR)); Using String Format: import java.util.Calendar; public class PrintDate { public PrintDate(){ //Create this for later String year =String.valueOf(Calendar.getInstance().get(Calendar.YEAR)); //Keeping the year 2015 //Format the date to keep it in a single String String date = String.format(“0%d0%d%d”, Calendar.getInstance().get(Calendar.DAY_OF_MONTH), … Read more
The below code uses the java Calendar class by setting it’s month to the input month and getting its max date by getActualMaximum() method. Also it will return 29 for leap years. public static void main(String args[]){ int month = 6; Calendar cal = Calendar.getInstance(); cal.set(Calendar.MONTH, month-1); System.out.println(cal.getActualMaximum(Calendar.DATE)); } 3 solved how to return the … Read more
Assume you’ve created a class for your Thread like Thread myThread = new Thread(new Runnable(…)); myThread.start(); you can wait for this thread to finish by adding the line myThread.join() as last line of yout while loop. This will cause the main-thread to wait for myThread to finish before it continues. So your code would look … Read more
Absolutely an interface cannot be initialized. Because it has no method implementation. It’s not a class! I should use classes that implement these methods. In fact I should use org.linphone.core (Library) instead of LinphoneCore (Intreface) solved How can I create a SIP connecton using Liblinphone interface class?
