问题 public class L20 { public static void main(String[] args) throws IOException{ Scanner input=new Scanner(System.in); System.out.println("Enter file name"); String in=input.nextLine(); try{ textWriter(in); textReader(in); textChanger(in); }catch(Exception e){ } } public static void textWriter(String path) throws IOException{ String[] alphabet= {"a","b","c","d","e","f","g","h","i","j","k","m","l","n","o","p","q","r","s","t","u","v","w","x","y","z"}; File file=new File(path); Writer output=null;

问题 I need to attach a specific script to a GameObject. public T ElegirScript<T>() { switch((int)tipoEdificio) // enum { case 0: return Edificios; // a class/script not instance break; case 1: return PlantaEnergia; // a class/script not instance break; default: break; } } gameobject.AddComponent<ElegirScript()>(); How can I make this? I have errors, thanks. I need first a Method that returns a type or a component, the return must be scripts. then I AddComponent and give the type the program

问题 I am creating a frame the uses the grid manager. And I have a label widgets in it. I want the label widget to fill to the frame that it is in. But instead the frame re sizes itself to the label widget. I have tried using the method grid_propagate(False). But it does not seem to be working. I don't know if it is just the way that I am using it but can someone help me figure out why it is not working? def fields(self): frame_row = 0 frame_column = 0 row_count = 0 color = "red" for i in range(50

问题 Just trying to understand the basics of how this should work. Here is my code.---------------------------> This is my main class. public class Driver { public static void main(String[] args) { //create new instance of the ArrayLab class with parameter of 10 ArrayLab array = new ArrayLab(10); //search for 2 array.search(2); } } The class ArrayLab has a method assigned to it called search with parameter of (2). So far this is what I have. import java.util.Arrays; public class ArrayLab { //array

问题 I am trying to use method chain with sub-methods. IE: foo("bar").do.stuff() The catch is stuff() needs to have a reference to the value of bar("bar") Is there any this.callee or other such reference to achieve this? 回答1: Is there any this.callee or other such reference to achieve this? No, you'd have to have foo return an object with a do property on it, which either: Make stuff a closure over the call to foo Have information you want from foo("bar") as a property of do , and then reference

问题 public class method { private static class Foo { public void hello() { System.out.println("Foo"); } } private static class Bar { public void hello() { System.out.println("Bar"); } } private static <T> void hello(T typ) { typ.hello(); } public static void main(String args[]) { Foo foo = new Foo(); Bar bar = new Bar(); hello(foo); hello(bar); } } I've looked at the other questions here regarding generics, but despite everything I've seen there and applied to the code I've written, I'm still

问题 Here is the code I'm having problems with: The interface: public interface anInterface { void printSomething(); } Class that implements the interface: public class aClass implements anInterface { public aClass() { } public void printSomethingElse() { System.out.println("Something else"); } @Override public void printSomething() { System.out.println("Something"); } } And the main function: public static void main(String[] args) { anInterface object = new aClass(); object.printSomething(); //

问题 Closed . This question is opinion-based. It is not currently accepting answers. Want to improve this question? Update the question so it can be answered with facts and citations by editing this post. Closed 6 years ago . Please help to come with a nice name for a method. Actually it is a scope that defines limit on date. This limit is from today and 365 days to the past, to the same day in past basically. So this is kind of rolling year I would say. This method is currently named #in_last

问题 public static void main(String[] args) throws IOException{ if (args.length == 1) { BufferedReader bf = new BufferedReader (new FileReader("fruit.txt")); int linecount = 0; String line; //run thur the txt file to check if input exist while (( line = bf.readLine()) != null) { linecount++; int indexfound = line.indexOf(args[0]); if (indexfound > -1) { System.out.println("fruit exist on line " + linecount); System.out.println("add another fruit"); System.exit(0); } else { BufferedWriter bw = new

问题 I have written this method to find the number of values that are greater than a specific value in an array and it works with arrrays that have positive integers but when I tried this test case it failed. public static int numGreater(int[] a, int val) { if (a == null || a.length == 0) { throw new IllegalArgumentException(); } int[] copy = Arrays.copyOf(a, a.length); Arrays.sort(copy); int answer = 0; int nearest = copy[0]; for (int i = 0; i < copy.length; i++) { if (Math.abs(nearest - val) >
