Múltiplos de um número em array

Qualquer número multiplicado pela sequência
dos números naturais, obtém - se os seus Múltiplos,
Veja abaixo a sequência dos Números Múltiplos de 2 até 5:

2 x 0 = 0
2 x 1 = 2
2 x 2 = 4
2 x 3 = 6
2 x 4 = 8
2 x 5 = 10

Portanto 2, 4, 6, 8 e 10 são Múltiplos de { 2 },
Partindo desta lógica ficou fácil criar este programa em java .
 Programei a saída para que só imprima entradas até 10,
isto foi usado como proteção para a visualização.
Aproveite o código e bons estudos.
