Kirat Adding a 0 to the end of the declaration helped the compiler infer the return type of the sum function: let mult a b = a * b let sum a b = a + b + 0 1 solved F# and type inference: “int list” does not support “+” [closed]
To read a file of “lines” in Java you can use the Files class like this: final List<String> l = Files.readAllLines(Paths.get(“/some/path/input.txt”)); This reads a file and stores each line in a List. When you have the List of String objects you can use a simple Comparator and the Collections.sortmethod. Check this code out: final List<String> … Read more
It depends on how you write your html. Assuming the footer element is always there: if (document.getElementById(‘footer’).childNodes.length == 0) { //If function find the copyright links, then null – don’t make anything } else //If function doesn’t find copyright links, then give an alert alert(“Please protect original copyright links.”) but remember, this just counts what … Read more
Solved by using this method: private static MainActivity instance; public MainActivity() { instance = this; } and changing the showtoast script to: Toast.makeText(instance, toast, Toast.LENGTH_SHORT).show(); solved Toast message crash app
It looks to me like perhaps the storyboard file was not added to the build target, so it can’t be found at launch time 1 solved IOS-Convert code-based interface to Storyboard based interface
don’n know exactly what do you want but below 2 code snippets can help you: 1.just use Replace: ‘remove tab characters Dim outString as String = inString.Replace(Constants.vbTab, “”) or ‘remove spacec haracters Dim outString as String = inString.Replace(” “, “”) 2.use an Split then use Replace in a loop through resulted array by Split: ‘split … Read more
iOS doesn’t support Flash, so you need to use Html5 instead. You can try Swiffy to convert an swf file into Hmtl5 or Wallaby to convert a fla file. But note that both tools are still a work in progress and may not work for you. Also, you can always write the html5 version yourself. … Read more
In your code it looks as though you are checking if the head of the snake collide with itself, which will always return True. You need to individually check that the head of snake does not collide with any of it’s trailing segments: for segment in SnakeSegments[2:]: if pygame.sprite.collide_rect(h, segment): pass # collision detected, game-over … Read more
You just need to print the number as a string. replace outputDegreesF() with public static void outputDegreesF(double degreesC) { double fahrenheit = 32.0 + (degreesC * 9.0 / 5.0); System.out.print(degreesC + ” ” + fahrenheit); // Easier // Or System.out.printf(“%.7f %.7f”, degreesC, fahrenheit); // Used more and lets you format } If you want to … Read more
You are calculating in metric but your g constant is in feet per second per second. solved Java Operations in Math Equations
This answer presumes the C implementation uses a 32-bit int and a 64-bit long. C 2018 6.4.4.1 says “The type of an integer constant is the first of the corresponding list in which its value can be represented.” In the table that follows, the entry for decimal constants with no suffix contains the list int, … Read more
the correct way is: int myreadfile(void) { FILE *fp; int i, n; unsigned char a[50]; if (!(fp=fopen(“x.exe”,”rb”))) return(0); while(n=fread(a,1,sizeof(a), fp)) { for (i=0; i<n; i++) printf(“%02x “,a[i]); printf(“\n”); } fclose(fp); return 1; } Note that the buffer is of type unsigned char. That is because a) you don’t know if the file is a complete … Read more
You seem to be getting an awful lot of different concepts confused, certainly more than could be sorted out in this form. One way to solve this would be a base class Product from which all your various “product types” derive, solving your first bullet point neatly, as any standard container could hold various types … Read more
This is basic Java and has nothing to do with Spring. Local variables and method parameters are initialized differently. For a method parameter the initialization is implicit because you must give some value to the method call. Example: // Declaration public String showForm(Model theModel) { } // Call showForm(null); You cannot ommit the argument and … Read more
