Anas Al-kamel You need to put everything inside try block if you want to catch them. Copy this code on Sololearn playground and see the effect import java.util.Scanner; public class Program { public static void main(String[] args) { Scanner sc = new Scanner (System.in); try { int n = sc.nextInt(); System.out.println("Hello " + n); } catch (Exception e) { System.out.println("Enter only numeric value => " + e); } } }

Alphin K Sajan well my code is about send some int and i will repeat it , but if there is something wrong as i mentioned above it will send an message like (‚ÄúHey you made somthing wrong!‚ÄĚ) could you help me with that ? int s = read.nextInt(); try{ }catch(Exception e){ System.out.print (‚ÄúHey you made somthing wrong!‚ÄĚ); }

You can use a while true loop and break after getting a correct input. Note that you have to use scanner.next() in catch or the program will use your last input instead of asking you for a new one. https://code.sololearn.com/cae77mMGy50H/?ref=app
