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 .
I'm trying to find a word in an array of char.....but I'm stuck. How to formulate the code to step through the array and pick out the word. This is what I have so far...
public static void searchAcross(String string, char[][] puzzle) { // Gets the number of rows in the matrix int rowLength = puzzle.length; //Gets the number of columns in the matrix. int colLength = puzzle[0].length;
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?
what will i compare in if statemet is the 1st letter of each if i have code="a" and name="Angelina" first letter of each is "a" and "A" then in convert it to string so that i can make it uppercase but when i compare it in if statement it always go into "not x" but the ouput that im getting is x=A y=A then it always direct me into else statement.
String code = "a"; String name = "Angelina"; char c = code.charAt(0); char n = name.charAt(0);
I am trying to figure out how to convert a string of ASCII code into char.I know that you can use (char) to convert it, but the issue is you cannot really just it for Strings.
First project here and it has been a steep learning curve. I have some code in the TwoWaySerialComm class that will write to a Com port. In my other class EBIAlarm i have my GUI. The aim of my app is the send strings out of the Com port by pressing Jbutton1-3 I can open the Com port but I don't know how to send the string.
How to convert numbers into string without using an array and a method ....
Example of arrayed code:
The code here is working but i want to use the other way for not using array just like switches and if and loops only. I made a code here but i did'nt run what i want to output .....
package UnderPackage; import java.util.Scanner; public class NumberToWords { static Scanner input = new Scanner(System.in); public static void main(String[] args) { int number; int b;
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');
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];
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.
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;

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?
I'm trying to take the information from one 2d char array and put it into another char array but instead of traversing the array left to right I want the new array to be top to bottom.
Example fg would be fh hi gi
I'm having trouble getting the information from one to the other.
[code]public static char[][] translateIt(char[][] english){ int rows = english.length; int columns = english[0].length; 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; }//Ending bracket of translateIt[code]
I have array contain numberi create new char array and i want to check if a number is >= 90 in array then input A at the same index in char arraythen second part i want to check if char array contain "A" then a = a + 1.
The result is like this:
A: 5 B: 29 C: 38 D: 24 E: 12 F: 17
public class Test { public static char[] grades(int[] getMarks) { char[] grade = new char[getMarks.length]; for (int i = 0; i < getMarks.length; i++) { if (getMarks[i] >= 90) {
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
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
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();
I have an array that I filled with 30 random characters, but now I am trying to sort them in ascending order and the descending order using lambda expressions.
public class RandomCharacters { public static void main(String args[]){ Random r =new Random(); char myarray[] = new char [30]; for (int i = 0 ; i < 30; i++)
I just tried to fill an array with some numbers, calculated by a other function.I just tried to print this array as array, but it doesnt work. Maybe its just about the main method.
public static void main(String[] args) { ggT(5); }
Creating an array searcher wherein it all depends on the user input. On the first user input it would be the array to search from while the second input would be something to be searched for inside the loop?
