I do not know how to read a name which has spaces in Java and I wish to learn. The following is my code
import java.util.*;
public class Asking {
public static void main(String []args) {
Scanner reader = new Scanner(System.in);
String [] names = new String[20];
int [] marks = new int[20];
My method below works fine to print a matrix but when it prints every row, it is printing extra 4 white spaces which is not required. How can I delete those extra spaces at the end? when I use

I am trying to write a program and the name variable can only store letters,dotes and spaces. But whenever I enter a space, the program doesn't work. Following is my code.
import java.util.Scanner; import java.util.*; public class Space { public static void main(String []args) { Scanner reader = new Scanner(System.in);
I am having a problem of how to write a program dat will input one number consisting of five digit,separate the number and print the digits separated from one another by three spaces each.. I tried to use divisional and remainder operation but it didn't work.
I am trying to split a string into a String[] tokens array to declare variables for an object; however, I'm having an issue getting the string to tokenize correctly. Here's an example of the input:
a : 100 : John Smith : 20 Main St. a : 101 : Mary Jones : 32 Brook Rd.
Here is the basic code I have now, to properly sort each line of text, etc. (without the split() method):
Java Code:
while (scanner.hasNextLine()) { currentLine = scanner.nextLine(); lineScan = new Scanner(currentLine); if (currentLine.startsWith("/") || currentLine.trim().isEmpty()) continue;
[Code] ....
I was able to eliminate the comments and identifiers from the text by trimming the first two characters of the string. For the split, I tried String[] tempArray = currentLine.split("s+"); however, that also took the spaces out of the addresses and names...so the results looked like this:
100 John Smith 20 Main St.
As you can see, it splits via space regardless, including where I replaced all the :'s with spaces. Is there any way to do this?
I am working on a small brain teaser project where I am taking a string input from a Scanner, and turning into ascii. The problem comes into play when the string has a space in it, so if the question is what's your name? and you say Michael Jackson, Michael gets converted then Jackson becomes the answer to the next question, rather then the second portion of the current string.
This is an older version of what I'm doing currently, but it had the same basic problem with spaces.I will say I did my current version entirely different.
nner user_input = new Scanner (System.in); //Creates a string String favoriteFlick; System.out.println("Enter the title of your favorite film?"); favoriteFlick = user_input.next();
public class ArrayPrinter { public static void main(String[] args) { int[] oneD = {5, 6, 7, 8}; PrintArray(oneD); } public static void PrintArray(int[] Arr) { System.out.println ('['); for (int i =0; i >= Arr.length; i++) { System.out.print (Arr[i]); if (i < Arr.length){ System.out.print(", "); } System.out.print (']'); } } }
I tried to format this to enhance readability but I'm not sure if I managed to improve it any... This code should be printing the contents of the array with spaces and commas its just printing [. I think this is because Arr is empty for some reason but I'm not sure why it would be when it gets the values of oneD passed to it.
I am trying to make a java code that reads in lines of text and returns the number of spaces in each line.I think i have made it but i can not compile it..
Here is my code:
class Mainh { public static void main( String args[] ) { System.out.print( "#Enter text : " ); String text = BIO.getString(); while ( ! text.equals( "END" ) )
I created a simple Hangman game. It functions correctly, the only issue is when the file contains a phrase (2 or more words), spaces are not displayed when the program is run. For example, if the phrase was Java Programming Forums.
It would appear as _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _.
I want there to be spaces in between the words. How could I fix this? What would I need to add to my code?
import java.util.Scanner; import java.io.*; public class hangman{ public static void main (String[] args) throws FileNotFoundException{ Scanner kb = new Scanner(System.in); String guess; String guesses = ""; int wrongGuess = 8;
Write an application that inputs one number consisting of five digits from the user, separates the number into in individual digits and prints the digits separated from the user, separates the number into its individual digits and prints the digits separated from one another by three spaces each.
For example, if the user types in the number 42339,
the program should input 4 2 3 3 9.
Here is my code so far but I am stuck.
mport java.util.Scanner; public class Seperating { public static void main ( String[] args) { Scanner input = new Scanner(System.in); int number = 0 ; System.out.printf("%d" , number ); System.out.print("Enter integer"); number = input.nextInt(); } }
but I am not getting the result I wanted what am I doing wrong
double sum = a + b + c; System.out.printf("Sum = %d", sum);
Heres the error I'm getting
Enter three positive integers separated by spaces, then press enter: 15 20 9
Sum = Exception in thread "main" java.util.IllegalFormatConversionException: d != java.lang.Double at java.util.Formatter$FormatSpecifier.failConversion(Unknown Source) at java.util.Formatter$FormatSpecifier.printInteger(Unknown Source) at java.util.Formatter$FormatSpecifier.print(Unknown Source) at java.util.Formatter.format(Unknown Source) at java.io.PrintStream.format(Unknown Source) at java.io.PrintStream.printf(Unknown Source) at project2.main(project2.java:52)
How to read xml tag <br/> without encoding in java. After encoding it becomes <br>. I dont want to encode it. I already tried CDATA[ and StringEscapeUtils.unescapeXml and StringEscapeUtils.unescapeHtml, but unable to change the decode it.
In Oracle SQL, when you do trim(column_name), if column_name is blank spaces only (say datatype is CHAR(8)), then "trim(column_name) is null" is true.
In JPQL, if you do "TRIM ( BOTH FROM p.column_name ) is null", does it evaluate to true just like in Oracle SQL?
The reason I'm asking, is my colleague wrote some code in JPQL like below:
... TRIM ( BOTH FROM CONCAT(p.column_name, '#@') ) = '#@'
He said he originally wanted to compare the TRIM result to empty String '', but the result is false, so he concat the column to some junk.
So if after the TRIM, the result is the same junk he added, then the column contains only blanks. I think this works but there could a simpler way to do it.
I have seen different methods of creating and reading files (specifically text files) in Java. The PrintWriter method or the Formatter with a Scanner to read the file, using a BufferedWriter with a BufferedReader, etc. They will all read/write text files, but from what I understand they do so in different ways. When would it be more beneficial to use a buffered writer than, say, PrintWriter, which is much simpler code-wise? Is there a "best" way to handle i/o in general in Java?
i don't have good grip in java, basically i am a software Tester and rightnow i am automating my application with Selenium (Testing Tool) so i need to write a script in java, so far i Worked with QTP for the same but in that its really easy to Data Driven test with Excel but here i am facing lots of problem. how to read/Write data from excel with java. how can i create input dialog box (like prompt in jscript) ?
