This question already has an answer here:
I am trying to convert upper case letters to lower case and I get the following error:
animalException in thread "main" java.lang.StringIndexOutOfBoundsException: String index out of range: 6 at java.lang.String.charAt(Unknown Source) at newproject.chars.main(chars.java:11)
Here is my code:
public class chars { public static void main(String[] args) { String a = "AnImAl"; for(int b=0;b<=a.length();b++) { char c= a.charAt(b); if(c>=65 && c<=90) { c=(char)((c + 32)); } System.out.print(c); } }}
Could somebody explain to me why I get this error? Thanks in advance
I have to generate a random customer IDs in the format 'abc123DFG'. The first three letters have to be lowercase the next three are numbers and the next three uppercase letters. I could make it simple by using unicode but this would be too big of a code I think. I want to keep it short and efficient.
PS: I am actually a very bad programmer but somehow I made it through the first semester.
I am trying to convert a char element from an char *argv[] array to lowercase from uppercase without using a function. I want to add 32 to the ascii integer.
When I try to pass the variable as an argument, it will show the integer sum, but not the new lowercase character. Instead it shows the following output:
letter h, 104tolower: 136, �
Code:
int i = 0;for(i = 0; argv[1][i] != '\0'; i++) { char letter = argv[1][i]; printf("letter %c, %i\n", letter, letter); char tolower = argv[1][i]; int lowercase = tolower + 32; printf("tolower: %i, %c\n", lowercase, lowercase);}
Why is it printing a "?" char?
Is there a way to convert a string from uppercase, or even part uppercase to lowercase?
E.g. Kilometers --> kilometers.
I have this code to autocomplete text.
I know I can add style to the input to make it appear uppercase (style="text-transform:uppercase")
The problem with this: it won't change to uppercase below (DOM)
How to do this?
var name1 = document.getElementById('name');name1.addEventListener('input', function() { var result = document.querySelector('.X'); result.innerHTML = this.value;});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script><label>What is your name? </label><input type="text" id="name" style="text-transform:uppercase" /><p>Your name is: <span class="X"></span></p>
