Question

I’ve been set an assignment which requires me to capture the input of 5 strings, convert them to uppercase, output them as a string, convert them to their Unicode integers (using the getNumericValue method) and then manipulate the integers using some basic operators.

I get the first part but I am having trouble with the following:

1. Using the getNumericValue to convert
   my single character literal strings
   into their Unicode integer
   counterparts.

2. Being able to assign these ints to
   variables so I can further process s
   them with operators, all the
   examples I have seen have been
   simple printing out the number and
   not assigning it to a variable,
   since I am a Java noob the syntax is
   still a little confusing for me.

My code is here

If there is a cleaner way of doing what I want please suggest so but without the use of arrays or loops.

Answer 1

I don’t understand why you don’t want to do this without arrays or loops.

You can get the unicode values (as ints) making up the string via String.codePointAt(), or get the characters via charAt() followed by a getNumericValue() for each character. But regardless, you’re going to have to iterate over the set of characters in the string via a loop, or perhaps recursion.
