Matriz de 4x4 Aleatoria En Java

<div class="TahomJustif10"><span style="text-align:justify;">Una matriz necesita dos índices para acceder a sus elementos. Gráficamente podemos representar una matriz como una tabla de n filas y m columnas cuyos elementos son todos del mismo tipo.</span><br /></div><div class="TahomJustif10"><br /></div><div

algo sencillo, pero si incrementamos el numero de sus lados, y mas aun si hacemos que la matriz sea Aleatoria, Te dejo el código de tal para que mires su funcionamiento y
