Which different between these two methods please?

	double somarValores(int a, int b){//um int cabe num double
			return a + b;
	}
	
	public Object soma (int valor1, int valor2){//faz a mesma coisa do método acima
		return (valor1 & valor2);
	}
	
	public static void main(String[] args) {
		System.out.println("O resultado da soma é " + new CriacaoMetodo().soma(2, 2));
	}

[Christophe Verré]

somarValores adds two numbers, like 1+2=3. soma performs a binary AND, like 0110 & 1100 = 0100 (see this).

[Rob Spoor]

These are definitely not the same. For example, 1 + 1 == 2 while 1 & 1 == 1.

...not to mention the return types.
