Hi calvin

Number is Super class of Integer, Float, Long, Double etc. and this
class is abstract class so you need to pass the the object of any
subclass of it.

By keeping the signature of this method with Number parameter , it is
being generalized ie you can pass any number object to this function.

HTH?

public class TestNumber {

public void doIt() {

Number aNum = new Float(123.45);

testNum(aNum);

}

public void testNum(Number n) {

System.out.println(n.toString());

}

public static void main(String[] args) {

TestNumber tn = new TestNumber();
tn.doIt();

}

}
