parseInt Java Tutorial - String to Integer #56

The parseIint java method lets use convert a string to an int:

Just replace the number 2 with the string you have. You can even use regular expressions to take out the integer you need if there are additional characters in your string, shown later in the video.

This String to Int java code can be tricky at first... But SURELY you'll get it :) If you followed along, congrats! You learned-by-doing!

I hope you enjoyed this parseInt java tutorial! I like to have a nice mix of tutorials and actual projects for you all :)

Was this able to help you convert your string into an integer? -

wow this was very helpful in a case I want to use this once in my code and not all the time.
very nice examples.
I saw a few other videos and examples from books but this was very very clear.

\D matches non-digits
\D+ matches one or several non-digits

Yet another informative video... Thanks to you!

Hi Alex. I'm rooting for your channel to grow. Love coding vids. On that note, for me personally, I found those little popups with their sound effects distracting at the bottom of the video. Perhaps once, at the top right, without sound would be better? Then just place your links in the Description area. Thanks and Cheers dude!

How do you use replaceAll?

Java String replaceAll() example: replace character

 1 public class ReplaceAllExample1{

 2 public static void main(String args[]){

 3 String s1="javatpoint is a very good website";

 4 String replaceString=s1.replaceAll("a", "e");//replaces all occurrences of "a" to "e"

 5

 6 }}

What is difference between replace and replaceAll in Java?

Java String replaceAll() Method Example

The difference between replace() and replaceAll() method is that the replace() method replaces all the occurrences of old char with new char while replaceAll() method replaces all the occurrences of old string with the new string.

i am confused about the last part yet where you get integer value 47 out of string "age:47". :(

[look_atyourself]

What exactly would you use the last method for? The only thing I could think of is if you were using a smart system, like voice to text in a calc or something, but I could be very far off.
