JAVA PROGRAM HELP

(Huge Integer Class) Create a class HugeInteger which uses a 40-element array of digits to

store integers as large as 40 digits each. Provide methods parse, toString, add and subtract. Method

parse should receive a String, extract each digit using method charAt and place the integer

equivalent of each digit into the integer array. For comparing HugeInteger objects, provide the following

methods: isEqualTo, isNotEqualTo, isGreaterThan, isLessThan, isGreaterThanOrEqualTo

and isLessThanOrEqualTo. Each of these is a predicate method that returns true if the relationship

holds between the two HugeInteger objects and returns false if the relationship does not hold. Provide

a predicate method isZero. If you feel ambitious, also provide methods multiply, divide and

remainder. [Note: Primitive boolean values can be output as the word “true” or the word “false” with

format specifier %b.]
