For example, here I put it only once, but I know that I can put it several times. What is the difference?
try{
if(tasks.size() <= 0){
System.out.println("Nothing to remove, no tasks");
}
else{
System.out.println("Enter index of task to remove");
int index = input.nextInt();
input.nextLine();
tasks.remove(index);
}
}
catch(InputMismatchException ex){
System.out.println("Please enter only numbers");
}
catch(IndexOutOfBoundsException ex){
System.out.println("Invalid index number");
}
}
