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 ?

Char Array To A String Array With Hex

Nov 16, 2010

I have a string array but each cell in the 1d string array stores each character the text file is :

"START START START
The quick brown fox jumps over the lazy dog 1234567890-= !"$%^&*()_+ QWERTYUIOP{}ASDFGHJKL:@~|ZXCVBNM<><? /.,mnbvcxzasdfghjkkl;'#][poiuytrewq789654123.0
+-*/``""$% hello this is a test file using all the characters availible on the keyboard for input END END END END"

so in the string it is:[0] = S, [1]=A, [2]=R ...ect along the text basically i need to convert each character in each cell of the 1d string array to its hesidecimal value..i have created my own method which will take in a char and return a string containing the charcters hex value.

public static String toHex(char c) {
char char2ascii = c;
int i = 0;
int num = (int) char2ascii;
String hex ="";

[code]...

what i want to do is run each cell through the toHex method so i eventually have a string array containing the hex value of each character in my text.

example..i want:

String[] hexarray = S, T, A, R, T

a run it through my method to convert to hex then it will become

String[] hexarray = 53, 54, 41, 52, 54

Im not allowed to use inbuilt libarys and classes to do the hex conversion thats why i have my own method for it .

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?

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)

Convert Array Of Integers To Array Of Characters And Then Print It Out

Feb 13, 2014

I have double checked this code over and over and I just can't find the problem.

What I'm trying to do is take a file and input it into an 2D array.

Ultimately, I should convert the array of integers to an array of characters, then print it out. The file contains a set of ASCII values.

After printing it out, I should then create methods to manipulate the image produced.

Using 2D arrays is a requirement for this exercise.

I think that somehow I'm overcomplicating this and the solution is a lot more simple than I think, but I can't think of what to change.

The error I am getting is:

Exception in thread "main" java.lang.ArrayIndexOutOfBoundsException: 40
at main.main(main.java:17)

Java Code:

import java.util.*;
import java.io.*;
public class main {
public static void main(String[] args)
throws FileNotFoundException {
String[][] data = new String[22][40];

Char Array Goes Out Of Bounds

Jan 16, 2014

Goal this time is to take a charArray, copy it into another charArray while reversing the things in it.

E.g. charArray["!ollaH"] into charArrayNew["Hallo!"]

My first idea was to revert the stuff in the Array with a ! cause i saw earlier that u can work with that too revert booleans. Sadly i didnt happen to make it work.

Next thing i thought of was a for loop to go trough the charArray and copy every section into charArrayNew just at the opposite end.

Java Code:

import java.util.Arrays;
public class aufgabe43 {
public static void main(String[] asgr){
char[] charArray

[Code] .....

Eclipse doesn't show any errors, and as u told me last time i did include import java.util.Arrays; to output the array in the end.

When i try to compile the code eclipse returns with an error

Java Code:

Exception in thread "main" java.lang.ArrayIndexOutOfBoundsException: 68
at aufgabe43.main(aufgabe43.java:8) mh_sh_highlight_all('java');

Which I frankly don't understand since the array . Length is exactly the same.

Least Significant Bit / Char Array

Oct 29, 2014

So I am working on a project for my Java course and for whatever reason, I am absolutely struggling with this assignment. I've made some progress but I can't seem to completely wrap my head around the algorithm I'm being told to use. I feel that everything is correct up to a particular point.I believe I am having issues moving a char array into a char matrix.

package edu.cofc.csci221.ui;
import java.lang.*;
public class Decoder
{
private int[][] M;

[code]...

Would I just need to loop through lsb one at a time and assign them to sequential spots within D? Basically call my get binary value and such in the outer loop and then use the inner to loop through both arrays and reassign values?

2D Char Array - Getting Information From One To Other

char[][] chinese = new char[columns][rows];
for(int j=0; j < columns; j++){
for (int i = 0; i < rows; i++){
//chinese[i][j] = english; this is commented out because it didn't work.
}//Ending bracket of columns for loop
}//Ending bracket of rows for loop

return chinese;

Creating A Window In 2D Char Array

May 17, 2014

I am relatively new to java, and i am trying to create a window inside of a 2d char array, and eventually i will have to draw other shapes in this window. so for example

* * * * * * * * *
* *
* *
* *
* *
* *
* *
* *
* * * * * * * * *

The problem is my window is not drawing correctly too the border, but a couple extra chars on the x columns. Here is code. The dimensions of the window will eventually be passed through scanner in main, if i ever work out how to even draw it.Also, in class we never learnt to use the Graphics class, so im pretty sure we are not supposed to use it.

public class Window
{ //default values
private int xRow;
private int yCol;
private char ch;
public char[][] windowz = new char[30][20]; //30,20 (yx)flat values cuz doesnt work

Character Converting Into Number In 2D Char Array?

Mar 29, 2014

I'm trying to convert all letters in a 2D char array into number. As results, I want a = 0, b=1, c=2, ... z=25.

Then, I tried this as part of my code:

char [][] letters = {{'i', 'u'}, {'a', 'g'}, {'e', 'k'}};
for (int i = 0; i < letters.length; i++) {
for (int j = 0; j < letters[i].length; j++) {
if (letters[i][j] >= 'a' && letters[i][j] <= 'z') {
letters[i][j] = (char) ((letters[i][j] - 'a') + '0');
}
}
}

The result of my code is not what I expected before.

From 'a' to 'j', it worked well. But, from 'k' until 'z' it didn't print expected number.

What's wrong with my code and what is the correct way to fix it?

Searching Large Char Array For Matching Substrings

Feb 10, 2015

I have written an algorithm that compares the chars and returns all the found words in a 20x10 puzzle, but not for a 100x50 puzzle.

The puzzles are loaded in via text file and I have confirmed they're loading correctly.

guesses = String[] of search words
puzzle = char[][] of letters

Why it doesn't work on the large array?

Expected output:
word1, word2, word3

Actual output:
[blank line]

Here's the horizontal algorithm (row by row search)

//temp variable
ArrayList<String> temp = new ArrayList<String>();
try {
//for each guess word
for(String word : guesses) {
int count = 0;

Servlets :: InputStream To Character Array Char In Java

Jun 27, 2014

I had a Rest web service call and get InputStream.Now i want to Write Input Stream to PrintWriter of servlet.So that it can be downloaded.I am able to write String and file can be downloaded using following code, i want it to work for Input streamFollowing is code:

response.setContentType("application/x-download");
response.setHeader("Content-Disposition", "attachment; filename="" + name + ".pdf"");
response.getWriter().write(is);

Write can take following:
write(String)
write(char[])
write(int)
write(String, int len, int off)
write(char[], int len, int off)

I think char[] will not harm PDF file which is going to download in it

Cannot Assign Cloned String Array To Generic Type Array

Jun 21, 2014

I have the following code in which I am looping through the rows of one array (composed of Strings) and copying it to another array. I am using .clone() to achieve this and it seems work as it changes the memory location of the rows themselves. I did notice that the String objects are still pointing to the same location in memory in both arrays but I won't worry about that for now, at the moment I just want to understand why the array I am cloning is not successfully assigning to the other array.

This is the incorrect line: ar[r] = maze[r].clone();

My code:

private String[][] maze = {{"*","*","*"," ","*","*","*","*","*","*"},
{"*"," ", "*"," "," "," ","*"," ","*","*"},
{"*"," ","*","*","*"," ","*"," ","*","*"},
{"*"," "," "," "," "," "," "," "," ","*"},
{"*","*","*","*","*"," ","*","*","*","*"},
{"*","*","*","*","*"," ","*","*","*","*"}};
//private String[][] mazeCopy = copyMaze(new String[6][10]);
private <T> T[][] copyMaze(T[][] ar){
for (int r = 0; r < ar.length; r++){
ar[r] = maze[r].clone();
}
return ar;
}

My compiler says: Required: T[]. Found: java.lang.String[]

Since ar[r] is an array and .clone() also returns an array why is this line incorrect.
