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');
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.
I need comparing two array lists. For this program i am comparing 2 array lists. The list is integers entered by the user the second is random generated numbers. So far in my program i am able to compare the 2 arrays together and output if they are equal or not however i need the program to output even if atleast one if the integers match,
EXAMPLE list one: 1, 2 ,3 ,4, 5. LIST TWO: 1, 3, 3, 3, 3.
Since the first number matches i want it to out put there is one match, so on and so forth with if there are 3 or 4 matching integers. here is my code so far.
public static void main(String[] args) { final int NbrsEntered = 5; //Number of guessed numbers entered final int LOTTOnbr = 5; int[] numbers = new int[NbrsEntered]; int[] randomNum = new int[LOTTOnbr]; //int[] TestArrayOne = { 1, 2, 3, 4, 5 }; //int[] TestArrayTwo = { 1, 2, 3, 3, 5 }; boolean arraysEqual = true; int index = 0;
I have this code that outputs the tfidf for all words in each file in the directory. I'm trying to transfer this to a matrix where each row correspond to each file in the directory and each column to all words in the files and I have some difficulty in doing it . Here is my try
public class TestTF_IDF { public static void main(String[] args) throws UnsupportedEncodingException, FileNotFoundException{ //Test code for TfIdf TfIdf tf = new TfIdf("E:/Thesis/ThesisWork/data1"); //Contains file name being processed String file; tf.buildAllDocuments();
I am aware that the default value of char is 0. But in this program I am getting some unexpected output
public class TestClass12{ static int[] ia = new int[1]; static char ch; public static void main(String args[]) throws Exception{ System.out.println("ch:"+ch+" ia[ch]:"+ia[ch]); } }
Output: ch: ia[ch]:0
If you see the above output ch is printed as a blank space instead of 0, while the array default value is correctly printed by taking the char default value as index. Why is ch printed as blank space?
I want to compere two element of string array by each other! eventually I want to print Yes or No in matrix . SO, I start reading data from file then split them into two parts .
File file= new File(fileName); try { inputStream = new Scanner(file); while (inputStream.hasNext()){ String data= inputStream.next(); String [] token =data.split(","); System.out.println("day"+token[0] +"embloyee name:"+ token[1]) ; } inputStream.close();
Now I want to compere each cell from token[0] by another array :
if the days are equal then I want print yes in front of the employee name if not then i want to print No..is this gone work with me as I imagine it to be or do I have to take few more steps to get my code going?
I am pretty new to Java and am just learning about two dimensional arrays. I think that I understand the concept, but I seem to be having trouble adding stuff to my array. I wanted to make an array to hold both strings and integers, but wasn't sure if I could put integers in a string array. So I thought that I would be able to convert my integers to string and then add them. This however causes an error. This is my code(yes its probably not the best):
static String [][] students = new String [14][4]; static int number = 0; String fName, lName, fullName; int test1, test2, test3, test4; String a, b, c, d;
Suppose I have private static void name() { ... } that has a two dimensional string array named array[. Now suppose I have private static void different() {...} and I want to write a condition where if (item == array) { ... }, how can I access my array from name() when I am in different()? I get a compile error saying cannot find symbol. My code is similar to:
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); } return printingString; }
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.
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");
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.
I want to cut my string from space char but i am getting exception....
Java Code:
import java.util.Scanner; import java.util.StringTokenizer; public class NameSurname { public static void main(String args[]) { Scanner sc=new Scanner(System.in); String s0,s1=null,s2 = null,s3=null; s0=sc.next();
[Code] ....
Console: Lionel andres messi Exception in thread "main" java.util.NoSuchElementException at java.util.StringTokenizer.nextToken(Unknown Source) at java.util.StringTokenizer.nextToken(Unknown Source) at com.parikshak.NameSurname.main(NameSurname.java:15) mh_sh_highlight_all('java'); I/p -O/p:
my s0=Lionel andres Messi
And I want to break it as soon as i find space and save it in s1,s2 and s3

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?
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:
