Read the Number Systems tutorial on the course website and Appendix J, Number Systems, in the course textbook. If you don't have access to Appendix J the tutorial will suffice. Then, write a set of methods that converts numbers between different number systems as follows: Method int binaryToDecimal( String binaryString) Description Parses a binary number entered as a String and returns the decimal equivalent as an integer. String binaryToHex( String binaryString) Parses a binary number entered as a String and returns the hexadecimal equivalent. String decimal To Binary( int decimalNumber) Returns the binary number equivalent of a decimal number. Returns the hexadecimal equivalent of a decimal number. String decimal To Hex( int decimal Number) Write an application that tests each of the methods
