methods

问题 Here is my method so far: public static int[] simplifyRadical(int number) { int[] result = new int[2]; for (int i = 1; i < number / 2; i++) { if ((i % number == 0)) { //IS a factor of the number in the radical } } return result; } The format I'm using is result[0] = number outside radical and result[1] = number inside radical . So far, my method gets all the factors of number (which is the initial UNSIMPLFIED number in the radical). So how can I divide the initial number by the perfect square

问题 In this example, how may I get the value of the i var inside the for loop, into guardarReserva() function? guardarReserva() and generarGrilla() are both methods of the same myApp object . var myApp = { generarGrilla:function(){ for(var i=1; i<13; i++){ var impresionGrilla = $('#grilla').append("one"); }; }, guardarReserva:function(){ var reservaConfirmada = $('#horario').append("two"); }, 回答1: You would need to define i outside of both functions: var myApp = { i:0, generarGrilla:function(){

问题 For Create And Start New Threads In C# We Act Like Below : using System.Threading; Thread thread = new Thread(new ThreadStart(WorkThreadFunction)); thread.Start(); public void WorkThreadFunction() { //Stuff Here } but what about methods with arguments. for these methods the codes below have an error. using System.Threading; int a = 5; int b = 6; Thread thread = new Thread(new ThreadStart(WorkThreadFunction(a, b))); thread.Start(); public void WorkThreadFunction(int a, int b) { //Stuff Here }

问题 I'm having trouble modifying global variables between different files in Python. For example: File1.py: x = 5 File2.py: from File1 import * def updateX(): global x x += 1 main.py: from File2 import * updateX() print x #prints 5 回答1: There are several important things to note here. First, global isn't global. The really global things, like built-in functions, are stored in the __builtin__ module, or builtins in Python 3. global means module-level. Second, when you import * , you get new

问题 I have code which should allow me to take value from calculator and use it further: //-----------------This section creates the keypad functionality for (int o = 0; o < keybuttons.length; o++) { final int n = o; keybuttons[o] = (Button) findViewById(data.keyIds[n]); keybuttons[o].setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { try { String tmp = texts[selectEdit].getText() .toString(); switch (n) { case 3: texts[selectEdit].setText(tmp.substring(0, tmp

问题 The deal is, I have to fix an error in a custom WooCommerce import plugin, which appeared after updating WC from 2.6 to 3.4. It uses the 'wc_update_product_stock_status' function, and used to pass post (product) id and it's stock status as it is represented in DB ('instock' and 'outofstock', as a string). But nowadays, as I can see in the WooCommerce docs (https://docs.woocommerce.com/wc-apidocs/function-wc_update_product_stock_status.html) it accepts integer instead of string. So, the

问题 I have class and interface: public class TestClass : ITestInterface { public int GetStatus() { return -1; } } public interface ITestInterface { int GetStatus(); } and I would like to dynamically create subclass of TestClass which will look like: public class TestClass2 : TestClass { public new int GetStatus() { return base.GetStatus(); } } I have some code which can create subclasses and overrides all virtual methods but when method is virtual final (GetStatus) I'm getting: "Declaration

问题 so im trying to learn recursion (i know in this case recursion is not necessary) i have already written this method, which works public static int method(int number) { if(number == 0) { return 1; } else { return (int)Math.pow(2,number) + method(number-1); } } this works perfectly for summing the powers of 2 from 0 to number, but i was wondering if there was a way to replace the Math.pow() with another recursive method call 回答1: You can use this as a recursive power function: public static int

问题 class Sup { private int i; //private one,not gonna get inherited. void seti(int s) //this is to set i.but which i is going to set becz i is also in child class? { i=s; System.out.println(i+"of sup class"); //to verify which i is changed } } class Cid extends Sup //this is child class { private int i; //this is 2nd i. i want to change this i but isnt changing on call to the seti method void changi(int h) //this one is working in changing the 2nd i. { i=h; } void showci() { System.out.println(i

问题 So someone please let me know what I am doing wrong here. My goal is to add the Motorcycle to mInventory (which I have created and imported from a separate package). However, I continue getting errors in my code. I took the Java course from Treehouse and now I'm trying to get out there and get my hands dirty using IntelliJ, but I can't help but feel like they really just threw us out there without really explaining how IntelliJ works. Anyone got some advice for me??? Here's Main.java: package
