问题 Let's say we have a class SCORE. It has three objects s1,s2 and s3. SCORE has an attribute RUNS. How to add the runs of all the objects ? SCORE has an internal method int TOTALSCORE(). so when that method is called, it should return the total score . How should i call that method ? Like s1.TOTALSCORE() ? Or any other way? 回答1: In rare cases the thing that you want could be reasonably, but normally the class is not aware of all it's elements. A total Score is for a Collection of Score elements

问题 I was looking for the ways to exit a method, i found two methods System.exit(); Return; System.exit() - Exits the full program Return exits current method and returns an error that remaining code are unreachable. class myclass { public static void myfunc() { return; System.out.println("Function "); } } public class method_test { public static void main(String args[]) { myclass mc= new myclass(); mc.myfunc(); System.out.println("Main"); } } 回答1: There is no best way, it depends on situation.

问题 I've just recently started my intermediate course in C# programming and I'm learning how to create multiple classes and creating methods to use in my program. It's a very new topic to me so I apologize if it's something very obvious or stupid. I am getting below message in all of my methods: Cannot access static method in non-static context Code in method class: public static int Add(params int[] numbers) { var sum = 0; foreach (var n in numbers) { sum += n; } return sum; } public static int

问题 I need to put the text content from an html element to a csv file. With the ruby csv gem, it seems that the primary write method for wrapped Strings and IOs only converts a string even if an object is specified. For example: Searchresults = puts browser.divs(class: 'results_row').map(&:text) csv << %w(Searchresults) returns only "searchresults" in the csv file. It seems like there should be a way to specify the text from the div element to be put and not just a literal string. Edit: Okay

问题 I have a method written like this... public void getRequest(String Url) { runOnUiThread(new Runnable() { public void run() { // TODO Auto-generated method stub HttpClient client = new DefaultHttpClient(); HttpGet request = new HttpGet(url); try { HttpResponse response = client.execute(request); Toast.makeText(MenuUtama.this, request(response) ,Toast.LENGTH_SHORT).show(); } catch (Exception ex) { ex.printStackTrace(); } } }); } I need to be able to access the local variable request in another

问题 This question already has answers here : Again and Again prints the same value (3 answers) Closed 5 years ago . I have been asked to check if the team name is present in the text file I had created on my computer. I have written the complete code but the output is always invoking me type the name of the team twice before counting the number of times the team's name is present in the file. Please do see this, and let me know. Thanks. import java.util.*; import java.io.*; public class

问题 I'm working with arrays and methods. I'm working on writing a code that will calculate the average of numbers entered by user in an array. I came up with the first method but VS tells me that "not all code paths return a value". When I tested the code in the Main() method it works well but when it's inside my GetValues() method i get the error. I read all other posts but they not quite make sense to me because of their specificity. I know this isn't too difficult but I'm a beginner and trying

问题 Need to make a method for taking an input, num= stdIn.nextLine(); and converting it into a binary string. "public static String toBinary(String num)". In Java. Any ideas? Can only find for int to binary. Needs to be string so user can enter "q" to exit program. 回答1: public static String toBinary(String num) { int convertedNum = Integer.parseInt(num); return Integer.toBinaryString(convertedNum); } Note that you should catch possible runtime exceptions because of the integer conversion of the

问题 let's take a simple program like this : public class Dope { public void a() { String t = "my"; int k = 6; } public void b() { System.out.println(t+" "+k);/*here it shows an error of not recognizing any variable*/ } public static void main(String Ss[]) { } } although i can correct it by just resorting to this way : public class Dope { String t; int k ; public void a() { t = "my"; k = 6; } public void b() { System.out.println(t+" "+k); } public static void main(String Ss[]) { } } but i wanted
