The document describes a Java program that defines classes for converting numbers between binary, hexadecimal, and octal representations. The BaseNumerica class contains methods to convert an integer to its binary, hexadecimal, and octal string representations. The interfaz class creates a GUI with labels, buttons, and fields to accept a number from the user and display its converted representations. When the conversion buttons are clicked, the appropriate method from BaseNumerica is called to perform the conversion.
