Convert String To Two Dimensional Char And Output Is Equal To Matrix

Jan 6, 2014

I have written the code:

Java Code:

public static void main(String[]args)
{
Scanner input = new Scanner(System.in);
System.out.print("Type your text: ");
String text = input.nextLine();
int counter = text.length();
if(text.length()> 16)

[Code] ....

And input is: abcdefghijklm

output is:

Java Code:

a b c d
e f g h
i j k l
m x x x mh_sh_highlight_all('java');

So all i want is, if i type: abcdefghijklm

I want this output:

Java Code:

a e i m
b f j x
c g k x
d h l x mh_sh_highlight_all('java');

Convert String Array To Char Array

Apr 12, 2015

I have an array of Strings, one on each line and I need to convert them into an array of char's.

For Example:

This
is
an
Example
of
what
my
input
is.

In order to accomplish that I did the following-

String[] lotsOfText = a.gettingAnArrayAsAReturn();
char [][] myCharArray = new char [lotsOfText.length] [lotsOfText.length];
for(int i=0; i<lotsOfText.length; i++){
for(int j=0;j<lotsOfText[i].length();j++){
myCharArray[i][j] = lotsOfText[j].charAt(j); }}

But whenever I try this and then try to print the output :

for (int i = 0; i < lotsOfText.length; i++) {
for (int j = 0; j < lotsOfText[i].length(); j++) {
System.out.print(myCharArray[i][j]);
}
}

I get nothing. I'm not sure what's the flaw in my logic, is it the char array initialization that's wrong or is it something else ?

Comparing 2 String Values?

Nov 8, 2014

I am trying some exercises on codingbat.com, and am stuck at the following program.

"Given a string, return true if it ends in "ly"."

With the following lines, if I type a print command instead of return, I get "ly". Yet if I aks to compare the result (which is "ly" as I can see with a print command) with == "ly", I get false?

What I also don't get, is that if I tye the programs in javascript, in that language the program works.

String str = "Oddly"
return ((str.substring(str.length()-2))== "ly");
}

Comparing String But /0 Keeps Being Counted

Apr 20, 2014

Ok I am trying to compare a string to see if all characters are unique. If there is a library for this or a better way to approach this do tell. However I find it important to understand what is going on behind the scenes. The issue is that the program counts the spaces '/0' and therefore everything will never be unique.

public class CheckUnique
{
private String sentence = "This will be compard";
private char[] checker;
private String isUnique = "The sentence is unique";
private String notUnique = "The sentence is not unique";

This program accepts Student ID numbers, Name, and grade point average. The problem I am having is with the if else statement that compares id to studentID[x].

How To Put All Char In Loop To String

Mar 16, 2014

I can't figure out how to have all of the random characters generated to go into the String. Below I can only get the last character to covert over to a String.

System.out.println("Original random character string:");
String printingString = "a";
for (int i = 0; i < 50; i++)//loop to obtain 50 random characters
{
char randomChar = (char) ((Math.random() * 255) +32);
System.out.print(randomChar);
printingString = Character.toString(randomChar); }

Getting Char At A Location In String

Oct 21, 2014

I found a fun program online and something so simple is giving me an issue. I c++ it is pretty simple fix, I can just call the strings location like an array. In java this is not the case. So far i have tried:

myString.charAt();
myString.indexOf();

There are a few other I found on google but I forget at the moment. I am just trying to close the gap on a string. It was a full sentence and I used replaceAll a few times to get several words I didn't want in the file out.

String [] token =data.split(",");
System.out.println("day"+token[0] +"embloyee name:"+ token[1]) ;

Check How Many Times Char Is Used In The String

Apr 1, 2014

I tried to make a program that takes a string str, and char a and checks how many times the char is used in the string.

Example: the string Welcome and the letter e, is 2 times. so the program should print 2.

It compiles but when I run it and enter the information, i cannot get the printing line out.

Heres my code:

import java.util.Scanner;
class program
{
public static void main(String[] args) {
Scanner user_input=new Scanner(System.in);
String str;
String b;
System.out.print("Please enter a word");

Unable To Count Each Char In A String

Jun 5, 2014

I am trying to count each char in a string. For example A = 1, B =2, C=3, I am not looking for their binary value. So the word "At" would

AT= (A=1 +T=20)=21.

I know how to do this in C++ because I am able to treat a string like an array.

Java Code: void printFile()
{
int sum=0;
String line;
for(char cr ='A';cr<'Z';cr++)
{
for(int i=0; i<myList.size();i++)

If Statement - Char To String Casting?

Aug 3, 2014

import java.io.IOException;
import java.util.*;
public class Guesser {
public static void main(String[] args) throws IOException {
 char[] alphabet = "abcdefghijklmnopqrstuvwxyz1234567890 .,:;'-".toCharArray();

[Code] .....

I'm writing a program which will take a three letter word (for now) and then try to guess the word over and over again until it finds it, then print the word and the amount of tries it took to find it.

The problem: at the moment the program will find the word but not break out of the for loop when it does. I think it doesn't like the char to String conversion somewhere along the line.

Why Print Char 0 (zero) plus String Does Not Work

Apr 3, 2015

I have a simple doubt. I was studying and create some code to check the result and I found out a strange situation.
 
Whats wrong with this code? Why it does not print anything?
 
char = 0; //integer value
System.out.println( c +" String ");
 
and why this next works very well?
 
char = 1; //integer value
System.out.println( c +" String ");
 
I know that char is stored as a positive integer and assign with 0 is different of assign with '0'.

How To Compare String Input To Char Array

Feb 8, 2014

What I'm trying to do is compare String input to a char array. Let me make it a little more plain, I'm working on a cipher assignment, and my line of thought is this: I will get String input from the user, COMPARE the characters in the string input to an alphabet array, which will then be compared to the cipher array so that the cipher's counterpart can be chosen over the alphabet's. Any way that I might compare the random input keyed in by the user to that alphabet array?

Return Given Char That Matches Input String

Apr 17, 2015

Processing a string. How would I only return a given char that matches the input string e.g. v and/or n and/or m.

Everything else that does not match will return a '*' - e.g. user input = t result = *

I assume I need to also iterate through this input string using charAt() ?

How To Convert Numeric String To Formatted String

Sep 11, 2014

I have a string value returned from a background tool that will range from 0 to possibly terabytes as a full number.  I want to format that number to use commas and to reduce the character count using an appropriate size modifier (KiB, MiB, GiB, etc).  I've tried converting the string number to a Double value using Double.parseDouble() and then performing the math based on the size of the value with this code:
 
Double dblConversionSize;
String stCinvertedSize;
dblConversionSize = Double.parseDouble(theValue);
if (dblConversionSize > (1024 * 1024 * 1024))
     stConvertedSize = String.format("%,.000d", dblConversionSize / 1024 / 1024 / 1024) + " TiB";
...
 
I've also tried using
 
     String.valueOf(dblConversionSize / 1024 / 1024 / 1024) + " TiB";
 
However, the formatting is failing and I'm either getting a format exception or the result is displayed as a number with no decimal component.

Cannot Convert From String To Boolean And Int To String

Apr 6, 2014

I have errors in the "if" and both "else if" ... The compiler says "cannot convert from String to boolean and int to String ...

instructions:

1. Add two private instance variables, String courseName and char grade to this class.

2. Add accessor and mutator methods for these instance variables.

3. Add a method register which receives an integer data type and returns String data type according to the argument passed to it ("Math" for 1, "English" for 2, "No course" for any other input)

What I have so far:

package assignment9;
 public class BannerUser
{
private int userId;
public int getUserId()
{
return this.userId;
}
public void setUserId(int userId)
