java中的方法重載，調用參數更小更精確的函數！

public void test(int number)
    {
        System.out.println("參數是int類型");
        System.out.println(number);
    }
	
System.out.println("-------------------------");
	
public void test(Integer number)
    {
        System.out.println("參數是Integer類型");
        System.out.println(number);
    }
	
System.out.println("-------------------------");
	
public void test(Object obj)
    {
        System.out.println("參數是Object類型");
        System.out.println(obj);
    }

Integer num = new Integer(66);
Object obj = new Object();
    test(88);
    test(num);
    test(obj);
