You are currently loading two grammers into your recognizer. I believe digits.gram contains numbers. File menuGrammar = new File(modelsDir, “grammar/menu.gram”); recognizer.addGrammarSearch(MENU_SEARCH, menuGrammar); File digitsGrammar = new File(modelsDir, “grammar/digits.gram”); So I think what you could do is make a file letter.gram and load it into your program #JSGF V1.0; grammar speech; public <speech> = A | … Read more
You have a red exclamaition mark on your project. Eclipse is likly to not build your project if build path problems (e.g.) aren’t resolved. So go to the Problems tab and try to resolve your errors there. If that is finished Eclipse will build your project and gives more helpful errors Edit and that is … Read more
The reason beeing is the compiler. At compile time the compiler does notice that the literal Hi exists twice in the code and does intern this string for your specific class. After compilation both of your interned strings Hi are pointing to the same reference of Hi. That´s the reason why the second print results … Read more
while loops? Why not use for loops? They are much better in this kind of situation i.e. when you want to repeat something a known number of times. You can use a nested for loop to make this happen: int counter = 0; for (int i = 0 ; i < 10 ; i++) { … Read more
Depending on your needs, it looks like something that could be solved using regex or string splitting by a regex number pattern then filtering out what you need. Example of doing the first line for matching 1 and 3 String s = “Z=1X1+3X2”; Pattern p = Pattern.compile(“([13])”); Matcher m = p.matcher(s); while (m.find()) { System.out.println(m.group()); … Read more
In a Java class, I can see that a class object and variable can have same name. Which value will be printed if they have same scope? solved In a Java class, I can see that a class object and variable can have same name. Which value will be printed if they have same scope?
Conversion To convert a String into a java.util.Date of a specific format, you can use a java.text.DateFormat. DateFormat objects can perform conversions in both directions, from String to Date by calling format() and from Date to String by calling parse(). DateFormat objects can be obtained in multiple ways, here are some: Obtain an instance via … Read more
In the future, you would be well-served to post at least some code that you have attempted to try to solve the issue on your own. As one of the comments mentioned, you will want to loop over the array using a for loop, and within that, check the comparison of the element you’re on, … Read more
This should help you for scanning Integer values. try{ System.out.print(“Enter an integer: “); int number = input.nextInt(); } catch (InputMismatchException ex) { System.out.println(“Incorrect input: an integer is required)”); //It’s also possible to throw your custom Exception here, like “throw new CustomException();” } About the IndexOutOfBoundsException, just write a try catch block around the area, where … Read more
In this statement Object[][] data = new Object[sheet.getLastRowNum()][sheet.getRow(0).getLastCellNum()]; It is creating an array of references to arrays of references to Objects. The first array is for rows and the leaf arrays are for column values. In reality, only String objects are added so I would write it like this. int rows = sheet.getLastRowNum(); int columns … Read more
Well. I cannot give you code… I can give you some advice.. Split the String based on semicolon (;). For each String in the array (which you got after splitting, except the last one) split it again based on “=”. Take the RHS of the split String and parse it as integer. Now parse the … Read more
First is declared object: Object ob; Note that declarations do not instantiate objects. When object is declared, its value is initially set to null. Second is declared and instantiated object: Object ob = new Object(); In this case you are initialize new object of type Object over constructor methods. Quick info you can get here. … Read more
Try: String s = “”; for(int i = 0 ; i < nLines ; ++i) { s = (i % 2 == 0 ? “1 ” : “0 “) + s; System.out.println(s); } solved Create triangle with “1” ” 0″ by for loop [closed]
Coming from the same country, I think I understand why she posted this question. The reason is quite complicated and and you may not understand unless you have a working understanding of the culture. Anyway, saying the following code is a better way would suffice. System.currentTimeMillis() – date.getTime() > 7 * 24 * 60 * … Read more
You could import the packages by putting this above your class declaration import packageA.Mypoint; or import packageB.MyCircle; Also, since a circle is made up of points, you could use inheritance, so all Mypoint methods will be available to objects created from the Mycircle class public class Mycircle extends Mypoint 1 solved How to connect two … Read more
