1.3 Overload constructors and methods

Exemplo:

public class TestClass {

	void probe(int... x) {
		System.out.println("In ...");
	} // 1

	void probe(Integer x) {
		System.out.println("In Integer");
	} // 2

	void probe(long x) {
		System.out.println("In long");
	}// 3

	void probe(Long x) {
		System.out.println("In LONG");
	} // 4

	public static void main(String[] args) {
		Integer a = 4;
		new TestClass().probe(a); // 5
		int b = 4;
		new TestClass().probe(b); // 6
	}
}
