You can pack your application in a .jar, actually a zip file with inside .class files and resource files. Those resource files, like your images, can be taken with getClass().getResource(“path/x.png”) or getResourceAsStream. The path is either package relative or absolute: “/abc/def.jpg”. These resources must be read-only (as they are inside the .jar). However you may … Read more
would like to know how ‘this’ is being used “this” refers to the current instance of a class. if there is another way of doing it with same end result. There is no need to explicitly create a Sequence variable in the append(…) method. You can just invoke the add(…) method directly and return “this”: … Read more
I’m not going to do your homework for you but here are some hints: You need to put all your code inside a class You need to put the code in the main method. (Search on Google) the method served for an entry point. You only need one for loop… Loop through the array, if … Read more
public static int min (int x, int y, int z) { int Min = (y>x)?x:y; Min = (z>Min)?Min:z; return Min; } public static int max (int x, int y, int z) { int Max = (y>x)?y:x; Max = (z>Max)?z:Max; return Max; } public static int average (int x, int y, int z) { return (x+y+z)/3; … Read more
What about this? Files.list(Paths.get(“somedir”)).sorted().forEach(System.out::println); 1 solved List of files in directory with new File API
Replace ViewPager.setAdapter(… with viewPager.setAdapter(… ViewPager (with a capital letter) is a class name and by using it here, you are trying to access the static method of that class. There is no static method setAdapter and hence the error. For readability, replace viewPager with pager. It will make it easier for you to avoid such … Read more
A simple RandomAccessFile scrambler would be this: private static final String READ_WRITE = “rw”; private static final Random random = new Random(); public static void scramble(String filePath, int scrambledByteCount) throws IOException{ RandomAccessFile file = new RandomAccessFile(filePath, READ_WRITE); long fileLength = file.getLength(); for(int count = 0; count < scrambledByteCount; count++) { long nextPosition = random.nextLong(fileLength-1); file.seek(nextPosition); … Read more
Yes you can do that but it would be better if you make the Males and Females into different classes and just inherit from the Human class. class Human: def __init__(self, height, weight): self.height = height self.weight = weight class Male(Human): def __init__(self, name): Human.__init__(self, height, weight) # This will inherit every attribute of the … Read more
You are counting numbers like 15, 30… (which are multiple of both 3 and 5) two times. So one alternative is to subtract these counts, you can add following loop after your two loops: for (int i = 0; i < 1000; i+=15) { count-=i; } You can also do the same in one loop … Read more
Since it’s recursive and the recursive call comes before your printline, it will recursively call itself over and over until it reaches the base case. Only first after the recursive calls have ended will your print be allowed to execute. Something like this Do something first recursive call Do something second recursive call Do something … Read more
You’re not checking clipboardContent for null. Just change: if (clipboardContent.length() == 5) {…} to: if (clipboardContent != null && clipboardContent.length() == 5) {…} solved Java, the clipboard code does not work, [closed]
Replace your setName function with this : public void setName(String name) { girlsName = name; } You forgot add param type. solved Java Simple Program Does Not Run
here you go: public static void main(String… args) { String[] verifiedNames = { “barry”, “matty”, “olly”, “joey” }; System.out.println(“choose an option”); System.out.println(“Uselift(1)”); System.out.println(“see audit report(2)”); System.out.println(“Exit Lift(3)”); Scanner scanner = new Scanner(System.in); int choice = scanner.nextInt(); switch (choice) { case 1: scanner.nextLine(); // get ‘\n’ symbol from previous input int nameAttemptsLeft = 3; while (nameAttemptsLeft– … Read more
You are right about the fact that == compares the references of the two variables, but, references are not the same as hash codes. Hash codes are numbers returned by this method that you’ve written: @Override public int hashCode() { final int prime = 31; int result = 1; result = prime * result + … Read more
It’s a very simple solution. You make a for loop which makes new numbers, and if it’s the first number you make, you add it to a temporary array. Then every time you generate a new number, you check with your array of already existing numbers, and then if it’s not unique, you add 1 … Read more
