Strings In Java - Adding Characters

Jan 13, 2015

It works when i do this ,
 
String a = "*";
for(int i = 0; i++; i<10){
 
System.out.println(a);
a = a +"*";
}

but it doesn't work the other way,

String a = "***************";
for(int i = 0; i++; i<10){
 
System.out.println(a);
a = a - "*";
}

I searched about this online and read strings are unmutable in java but what does that exactly mean ? If the string cannot be changed how i am able to add the characters but not remove them.

Ignore Certain Characters In A String

Apr 5, 2014

I'm trying to loop through a string and depending on the character, add a JLabel to a game. The problem is the character 'L' represents a lantern but is also used in the reply the game gives which is "LOOKREPLY". I've tried to use some code to ignore the LOOKREPLY bit but it's not working. Here's what I've tried.

else if(message.charAt(i) == 'L' && message.charAt(i+1) != 'O' | message.charAt(i+1) == 'Y'){
JLabel localLabel = new JLabel();
localLabel.setIcon(lantern);
panel.add(localLabel);
panel.revalidate();
panel.repaint();

But the first image on all of the JLabels is always a lantern, which is what L represents. As it's only 1 lantern this leads me to believe that it's ignoring the first 'L' but for some reason it's not ignoring the 'L' at the end of LOOKREPLY.

Replacing Characters In Array?

Mar 7, 2014

Is that the only way to code the JOptionPane? Seems rather similar to Sys.out

--- Update ---

I had more than this, but post was deleted somehow and this was the gist of it:

for(i = 0 ; i < charArray.length; i++){
if(Character.isDigit(charArray(i))){
address.replace("6", "*");
address.replace("7", "*");

Is there a better way to scan a character array for digits and replace any number in the array with another character ("*") in this case? The array is the address, " 1234 Runner Road " .

Getting Characters Into Array From A String

Oct 17, 2014

As of right now my code can take characters from a string to an array from a string like "ABCD" but the project says I have to take it from a string like "A B C D" how can I correct my code to grab the characters from a single spaced line?

Scanner sc = new Scanner(System.in);
System.out.println("Enter Order of Cars:");
String carsInput = sc.next();
int x = carsInput.length();
int[] cars = new int[x];
for (int i=0; i < cars.length; i++) {
cars[i] = carsInput.charAt(i)-64;

Combining Characters Into A String

Sep 10, 2014

So what my program is supposed to do is take a number inputted by the use and then take a phrase. It then changes that phrases letter by the number inputted prior for example if you type in 2 as your int and Hello as your phrase you should get JGNNQ, which i can do. but the problem is that when i run it, it outputs like this:

J
G
N
N
Q

As separate characters how can I combine those characters in 1 string so it looks like JGNNQ? this is my code

import java.util.Scanner;
public class Dcod_MAin {
private static final Object[] String = null;
public static void main(String[] args){
Scanner input = new Scanner (System.in);
System.out.println("What is the day of the month");
int shift;

Removing Specific Characters From A String

May 7, 2014

I just need to write a simple program/function that replaces certain letters from a string (i.e. censor( "college", "aeiou" ) returns "cllg"). I'm trying to get the code right first, and then write a function for it.I basically just thought that I would iterate over the first string, and once I had the first character, I would then iterate over the second string, to see if the character exists. I'm getting a "dead code" error on my second loop because I put the second "break."

public class ap {
public static void main(String [] args){
String s = "Hello";
String s2 = "aeiou";

Adding Characters To Result Stack

Feb 21, 2014

Right now I have three stacks. Each stack holds characters, with the normal operations of pushing and popping. I am trying to compare two characters from stack1 and stack2(each character is a digit character). I would like to be able to do arithmetic on the digit characters and the push the answer on to a result stack.

Ex.) I pop character '3' from stack1 and '5' from stack2. Then I add the two. equaling '8' and pushing that character on to the result stack. This will hopefully in turn allow me to add arbitrary large numbers that integers will not support.

I am having trouble because I believe I am getting some ascii character values when I pop off the result stack. here is a small piece of my code

public void addition() {
char temp1 ,temp2;
int i = s1.getSize();
for(int j= 0;j<i;j++) {
temp1 = s1.pop();
temp2 = s2.pop();
if(temp1+temp2>=10)

[Code] .....

Stack Is Filled With Numbers And Characters

Oct 31, 2014

I have a Char stack: ArrayStack<Character> stek=new ArrayStack<>();

The stack is filled with numbers and characters (only '+' and '*' ), but I need to make calculations, so I need the INT values of the numbers i pop from the stack. So each time I need to make a calculation, I have to pop two numbers, convert them into INT ,then add/multiply them, and put them back into the stack again, but as CHAR (because the stack is not accepting them to be added as INT)

int a= Character.getNumericValue(stek.pop()); //stack no1
int b= Character.getNumericValue(rezultat.pop()); //stack no2
int tmp=a*b;
char tmp2 = (char) tmp;
stek.push(tmp2);

How To Check A String For NON-Alphabetic Characters

Oct 2, 2014

I have to check a String input from the user in the form of firstName lastName (i.e. John Smith). I have to check for an exception called NonAlphabeticCharacterException that gets thrown if there is anything but a number in that string. This is what I have right now but should I create an array of char for the alphabet and then check the whole string for non alphabetic characters?

for(int i=0; i<name.length(); i++) {
if()){
throw new NonAlphabeticCharactersException("Non-alphabetic character found");
}
}
