Numeros Pseaudoaleatorios

Generación de Números Pseudo aleatorios.

Objetivo: Realizar un programa en lenguaje Java donde introduzcas una semilla (numero aleatorio), y a partir de este, se generen una serie de número pseudo-aleatorios los cuales van desde el 0 al 1.
Métodos a utilizar:
1. Método del cuadrado medio
2. Método Congruencia Lineal
3. Método de la función “Random” de Java
Una vez generados,se elabore una gráfica donde se visualice la aleatoriedad de ellos.
