The Birthday Paradox predicts that the probability of duplicates in random numbers is much higher than you’d think. For example, it predicts that, with a mere 23 random people, there’s a greater than 50% chance of two of them have the same birthday. By the Pigeonhole Principle, it takes 367 people for there to be … Read more
You should put the constructor inside the class, like this: public class Galaxy { String galaxyName; int galaxySolarSystems; int galaxyPlanets; long galaxyColonies; double galaxyLifeforms; int galaxyFleets; int galaxyStarships; public Galaxy(String name, int solarSys, int planets) { galaxyName = name; galaxySolarSystems = solarSys; galaxyPlanets = planets; galaxyColonies = 0; galaxyLifeforms = 0; galaxyFleets = 0; galaxyStarships … Read more
It would basically go something like this: ResultSet rs = statement.executeQuery(yourSQLQueryString); // Get your ResultSet from Database rs.last(); // Place the record pointer onto the last row int counter = res.getRow(); // Get the row number (there’s your count) rs.first(); // Place the record pointer onto the first row for the while loop String[] myArray … Read more
You must have a main method to put your code in. Like this: public class Character public static void main(String[] args) { System.out.println(“Enter your new character’s name.”); System.out.println(“\t”); new Character(input.nextLine()); } public Character(String name) { this.name = name; } String name; int level = 1; int XP = 0; int maxHP = 20; int HP … Read more
If what you want is a division method faster than division by repeated subtraction (which you posted), and that will run indefinitely when you try to divide by zero, you can implement your own version of the Goldschmidt division, and not throw an error when the divisor is zero. The algorithm works like this: 1. … Read more
Here is the java Version private Boolean isDarkTheme(Activity activity) { return (activity.getResources().getConfiguration().uiMode & Configuration.UI_MODE_NIGHT_MASK) == Configuration.UI_MODE_NIGHT_YES; } Java getResources() ->Kotlin resources Java getConfiguration() ->Kotlin configuration Java & ->Kotlin and as you see it’s simple Setters and Getters in koltin are accessed by property name solved Is anyone still using Java? Can I have this translated … Read more
l2FileNAme: scenario8_items.txt Counting the characters on the screen, the . is in the 16th place, which is 15 in a zero-based indexing. You’re performing this on l2. Seems like the correct output to me. solved Why is indexOf returning an incorrect index? [closed]
== compares references not the content To compare strings you need to use String#equals: .equals(); //If you consider the case .equalsIgnoreCase(); //If you not consider the case 0 solved What’s wrong with == operator on java string [duplicate]
Other responders have given you a better way to write this, but to specifically address your original question, the reason you’re getting an “unexpected” (to you) value of “low” is that you’re assigning each entry of the array to “low” unconditionally. The entry with “5” is the last entry that you process, so that’s the … Read more
To print something in java, you need to actually call the function that would print to the standard output. In other words, you need to use System.out.print(What_you_want_to_print) To see the output for your code, you need to adjust your code as follows: import java.io.*; public class Solution { public static void main(String[] args) throws Exception … Read more
If you enter your question without the xml tags in Google, you find enough information on the first page. I propose to check out the JAXP trail of the Oracle Java SE Tutorial, which shows you how to do it the standard Java way. And then, as your XML example suggests, if you want to … Read more
If you have Read CODE little more carefully……..You could understood by your own..because there is comments defined there for understanding that code………… Though,below there is description for the code … Its A Activity For Creating SPLASH SCREEN…………. IT uses Handler which runs after specified time Defined In.. SPLASH_TIME_OUT There is 1000 = 1 Sec; So … Read more
So I see two glaring errors, the first of which is what the compiler is telling you, namely that real and imaginary have not been declared anywhere. In Java, you cannot use a variable unless you have previously declared it. You probably want to have a real and imaginary component of your ComplexNumber, so you … Read more
If you do not have a constructor the Java compiler will create a no-arguments constructor for you. As soon as you provide a constructor which has arguments the no-argument constructor does not get created by the compiler. So if you add a no-arguments constructor to InVoice (like below) it should work. public InVoice() { } … Read more
static void placeRandomly2D(int[][] arr, int limit) { // generates value [0…limit) half-interval and places it into the 2D array arr // at random position; limit must be positive Random rand = new Random(); int value = rand.nextInt(limit); int pos1 = rand.nextInt(arr.length); int pos2 = rand.nextInt(arr[pos1].length); arr[pos1][pos2] = value; } And, just in case, version for … Read more
