Console-based piggy bank

lmao i literally completed this with correct logic except was getting an error since i was checking for a string equality with == instead of .equals() i legit had studied this is aswell. oh well, wont make the same mistake again. for anyone else make sure to check that also

I just used try and catch with a scanner

If you go stuck on this, here is a hint: We know the only inputs are going to be either "sum" or a number, hence after we have checked weather the input is "sum" or not we can convert the String to an int :)

Just a hint - Scanner class lets you check what data type is there before you read it. I did the task for doubles, it looks like while(input.hasNextDouble()) sum+=input.nextDouble();

Pls guide: what is wrong here

Guys please how do we extract 23 from the String "sum23"? Is it even possible?

I overcomplicated this one, created an elaborate "isThisAnInteger" testing mechanism that would parse the text to an an integer only if it passed the test and add it lol. After reviewing other classmates work I see that this is just too much work for this, instead all you need to do is check if the string is "sum" and if not, then parse and add ;) HAHA Was fun to learn how to do a "type" check script tho! now i can make anything into anything ;)
