Assignment

Create a class that manipulates binary numbers

Constructors:

Binary$()//$ default constructor that creates the array

Binary $($Binary anyBin$)//$constructor that copies a given Binary and creates a Binary object Binary$($String bitString$)//$constructor that converts a String of $1$ s and $0$s to a Binary object Binary$($int num$)//$constructor that converts a decimal to an Binary object

Binary$($int$][)//$ constructor that uses an int$[$ to create a Binary object Bits

Methods:

public String toString$()//$ Converts a Binary object to a String

Binary not$()//$ Returns a new Binary object that is the logical "not" of the Binary object

Binary or$($ Binary rhs$)//$ Returns a new Binary object that is $"$or$"$ed with the Binary object

Binary and$($Binary rhs$)//$ Returns a new Binary object that is "and"ed with the Binary object

Binary add$($Binary rhs$)//$ Returns a new Binary object which is the sum of the Binary object and the rhs

Binary twosComplement$()//$ Returns a new Binary object that is the twosComplement of the Binary object

Binary int$2$bin$($int num$)//$ Returns a new Binary object that is the decimal number converted to binary

Binary rotateRight$()//$ Returns a new Binary objhct that is a copy of the Binary object rotated right by one digit

Binary rotateLeft$()//$ Returns a new Binary object that is a copy of the Binary object rotated left by one digit

int bin$2$int$()//$ Returns an int that is the decimal value of the Binary object static void test$()//$ tests the methods of the Binary class
