LongInteger Class

Implement a class named LongInteger. The class contains:

A private data field of type long

A constructor that takes parameter of type long and creates LongInteger object for the specified long value.

toLong$()$ method that returns the value of the field.

The instance methods isEven$(),$ isOdd$(),$ and isPrime$()$ that return true if the value in the object is even, odd, or prime respectively.

The static methods isEven$($long$),$ isOdd$($long$),$ and isPrime$($long$)$ that return true if the specified value is even, odd, or prime respectively.

The instance method equals$($long$)$ and instance method equals$($LongInteger$)$ that return true if the value in this object is equal to the specified value.

A static method parseLong$($String$)$ that converts a string into an long value, positive or negative. Method throws IllegalArgumentException when

A string contains non$-$digit characters $($other than $\text{'}-\text{'}$ as the very first character of the sting$).$

A string has only $\text{'}-\text{'}$ and no digits.

A string represents a number that is too large to be stored as long and produces overflow

A string represents a number that is too small to be stored as long and produces underflow
