Number-System-Conversion-in-Java

Introduction The Number Converter is a Java program designed to facilitate the conversion of numbers between different number systems, including decimal, binary, octal, and hexadecimal. It also supports the generation of 1's and 2's complement binary representations for both positive and negative numbers. This program serves as a useful tool for computer science students, programmers, and enthusiasts who frequently work with different number systems and need a convenient way to perform conversions accurately. With its simple and intuitive interface, users can input numbers in one number system and quickly obtain their equivalents in other number systems. Additionally, users can generate the complement representations of decimal numbers, which are commonly used in computer arithmetic and digital logic circuits. Features Number System Conversions • Convert decimal numbers to binary, octal, and hexadecimal. • Convert binary numbers to decimal, octal, and hexadecimal. • Convert octal numbers to decimal, binary, and hexadecimal. • Convert hexadecimal numbers to decimal, binary, and octal. Complement Representations • Generate the 1's complement binary representation of decimal numbers. • Generate the 2's complement binary representation of decimal numbers. User Interaction • Interactive command-line interface for inputting numbers and viewing conversion results. • Easy-to-use interface suitable for both beginners and experienced users. Overview The Number Converter Java program provides methods to convert numbers between different number systems including decimal, binary, octal, and hexadecimal. Additionally, it supports the conversion of positive and negative numbers, as well as the generation of 1's and 2's complement binary representations. Usage To use the program, compile the NumberConverter.java file and run the compiled program. The program will prompt the user to input numbers for conversion and display the results accordingly.
