It would be better if explained with an example.

Hi Rita,
I believe all the wrapper classes are immutable too. If you look at the
JavaDoc for the Integer class you can see that the class is final. So it is
immutable.
public final class *Integer*extends Number
implements
Comparable

Hi Rita,
In Example 2,
I search the Integer.java for the answer.
When you are using autoboxing (just like Line 026) , you will get a new
Integer object in fact.
So when you use "==" for compare the reference, it will not true.
But be caution, the implement of autoboxing mechanism in the source

Dear Java Programmer:
Here hex is a string. A 10 is entered into the JOption pane. This is
recognized as a character of '1' and '0'.
//This comes into this method and the length of 2 makes
//a one dimensional array of 2 with the values [0],[1].
int intEq[] = new int[hex.length()];
//hex.le

HI;
Your instructions to bring up the classpath at my command prompt did not work.
I used this instead:
echo %PATH% echo %CLASSPATH%
This worked for my system?

Hi Pedro,
For your queries..
1. It is not mandatory that the ages are between 3 and 6. It's your choice.
The number of family members to take into account for average age
calculation can be between 3 and 6. For example, if you take 4 members of a
family, say, A, B, C and D with the ages 6, 10, 12

Thanks gpatynek I replaced my loop with your triple loop.
I now get this message -
Operator + cannot be applied to java.lang,String, k
cannot find symbol
symbol : variable k

cannot find symbol

location: class threedimensional
It's complaining
Pedro,
Lets say you want 4 names and ages in the format name1 age1 name2 age2 name3
age3 name4 age4, you could pass them as arguments into your code ... see
below. This code does the folllowing:
verifies if the total number of arguments passed is 8
initialize variables to store the values of args
Hi,
I have some questions regarding the Homework exercise of Lab - 1038.
1 - Regarding numbers of ages, is it mandatory for the program to check if
the ages passed as command-line arguments are between 3 and 6, or is a
programmer's choice?
Because that is a problem when making the average, if

I just want to point out an interesting fact when casting int values.
In pdf document "Working with built-in Java classes", page48, it says:
int numInt1 = 1;
int numInt2 = 2;
//result is implicitly casted to type double
double numDouble = numInt1/numInt2;

All:
Due to help from BlackRookSix and Pacior, the mystery of CLASSPATH is
resolved. I hope that this will help others.
If there is ANY value in your CLASSPATH variable, you CANNOT use Set

BlackRookSix suggested using echo %CLASSPATH% to obtain the curren

Hi there,
I hope I'm wrong on this, but I think that:
1) Memory allocation is a runtime task. By default, the JVM does nothing
in compile time about choosing memory addresses or such.
2) Since everything is ran from inside a Virtual Machine, consider only
the Java heap space. Of course at som
Hi Mahmoud,
Indeed you should try read the api, on the methods used in the code, to
figure out what each line does.
But there is a minor catch in this code:
// set a property through setProperty() method
p.setProperty("myKey1", "myValue1");
Yet, the expected output in the end doesn't have this
Hi Torres,
You cannot extend but you can always convert from String to Long.
Lets look at a code sample here :
public class TestConversion {
public static void main(String[] args) {
String number = "10";
Long convertlong;
convertlo
