Code Point Question

Every character defined in the Unicode standard is given a specific number called a code point. These code points are written as hexadecimal numbers prefixed by "U+". For example, the character "A" is U+0041.

Write a Java program that accepts a range of Unicode code point numbers from the user (i.e., U+0041 to U+0051) and then displays all the Unicode characters that are contained within that range. The question is can your program display the characters for the range U+0021 to U+007F?

Hint: If you need to find a way to convert a hexadecimal code point to a character, have a look at the methods of the Character class.
