Big Integer Calculator

Description

This program works similar to Java BigInteger in that operations are performed on Strings rather than ints. Each function breaks the Strings into arrays of individual ints and returns a String object. The 4 functions are:

• Add
• Subtract
• Multiply
• Divide

Instructions

This program requires the JAVA JDK to be installed.

Compile:
javac BigIntCalc.java

Run:
java BigInt [num1] [num2]

or

Call the static methods:
add(str1, str2)
subtract(str1, str2)
multiply(str1, str2)
divide(str1, str2)

Rules

[num1] >= [num2]
[num2] != 0

The program operates [num1] + [num2], [num1] - [num2], etc.
