After user input wrong numbers

Answer 3

This happening because you have created this method but you not using anywhere i mean u not calling thia method

public static int validation(int n,String sub,Scanner sc){
//Scanner sc = new Scanner(System.in);
if(n>100){
System.out.println("You can't have 100+ marks in "+ sub +"\n");

System.out.println("please enter again marks of "+ sub);
n = sc.nextInt();
return n;

Balram Singh this is static method i know u dont need to create object to call this validation method . Its not a constructor but where u calling this method and tell me one thing after this line please enter again marks why u taking this input it have no sense to return if u want to re-enter marks again then make one more method and put your all code which have written in top after validation method call it after first method it will ask for input again
