Deleting Spaces In Java Code

Mar 1, 2014

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

System.out.print((matrix[i][j] + " ").replaceAll("^s+", ""));

It trims every thing including the spaces I needed for my matrix. So where should I put replaceAll("^s+", "") ?

Java Code:

private static void printMatrix(int[][] matrix) {
System.out.println();
System.out.println("Matrix:");
for (int i = 0; i < matrix.length; i++) {
for (int j = 0; j < matrix[i].length; j++) {
System.out.print(matrix[i][j] + " ");
}
System.out.println();
}
} mh_sh_highlight_all('java');

How To Add Spaces To A Pattern

Apr 21, 2015

I have created this program that outputs

1
12
123
1234
12345
123456

I tried looking up some ways to create spaces in between each number, but I failed miserably. Here is what I have right now.

public class Iterations {
public static void main(String[] args){
for(int i=1;i<=6;i++)
{
for(int j=1;j<=i;j++)
System.out.print(j);

Padding Will NOT Work - Adding Spaces?

Apr 22, 2014

Why this will not pad?? It keeps displaying normally, even if i add spaces it will not work.

System.out.printf("%-20s%-20s%-20s%-20s", p.getLastName(),
p.getLastName(), p.getSocialSecurityNumber(),p.getAge());
This is what it is printing:

=================== =================== ====================== ===
lastname, firstname, 123-12-1234, 16

The lastname, firstname, 123-12-1234, 16 should be padded and appear with about 20 spaces between them.

Splitting A String While Keeping Some Spaces

Jan 21, 2014

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?

String From User Not Removing Spaces

Apr 6, 2014

I'm not sure why but my infix string isn't removing the spaces. Here is the part of the code:

Scanner s = new Scanner(System.in);
System.out.println("Enter Infix express: ");
String infix = s.nextLine();
infix.replaceAll("\s", "").trim();
System.out.println(infix);
InfixtoPostfix convert = new InfixtoPostfix(infix);
String postfix = convert.toPostFix();
System.out.println("Converted Express: " + postfix);

Is there something I'm doing wrong? Here is the output when I run it:

Enter Infix expression:
(7 + x) * (8 – 2) / 4 + (x + 2)
(7 + x) * (8 – 2) / 4 + (x + 2)
Converted Expression: 7 x+ 8 – 2* /4 x 2++

Dealing With Spaces During Input String Conversion?

Oct 5, 2014

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();

Audit File - How To Add Certain Number Of Spaces For Each Line

Feb 7, 2014

I create a Audit file within my Java program, which gets all the System.out.println lines from the code.

For example, the System.out.println lines in my code are as follows:-

Records initially inserted into edited: 70144

Bad license number records removed: 5

Total records in edited: 70139

Records initially inserted into tabedited:7463

I want all my values aligned after the statement, when they are printed to the Audit File.

Instead of just giving spaces by counting the number of charaters in the line, is there any other way to align them.

Not Printing Contents Of Array With Spaces And Commas

Nov 7, 2014

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.

How To Delimit Spaces In User Input Separating Two Data Types

Jan 17, 2015

I am creating a calculator in which a user will directly input the numbers and the operator...

Here is my code:

int answer = 0;
int num1, num2;
char operator;
System.out.print("Enter calculation: ");
num1 = kb.nextInt();
operator = kb.next().charAt(0);
num2 = kb.nextInt();

The code above will accept the user input when there are spaces like this: 1 + 1

So the program will give an answer which is 2...BUT

if i input 1+1 it will give an error...Exception in thread "main" java.util.InputMismatchException

How can i do that it will separate integer to character? because i set the operator as character....

So that it will accept one digit to several digit numbers... like 500+84 or 1520+872??

Multi-word Hangman Game - Spaces Not Displayed When Program Run

Apr 9, 2015

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;

Separating Integers Into Individual Digits And Print Separately By Three Spaces Each

Mar 11, 2014

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

Enterprise JavaBeans :: JPQL Does TRIM Column Containing Only Blank Spaces Returns Null?

Oct 6, 2014

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.

Best Way To Read / Write Files In Java?

Mar 31, 2014

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?
