Hi, I have a confusion with java loops, I’m a student and I don’t understand how after you are at the end of the program loop back to the middle, to do a step again. I don’t understand where to put the loop. I tried, while, do while and if else, but I’m very confuse. Please help.

Check out this tutorial for Sun's tutorial of loops in Java.

you can write some sample code,try to execute it.post the erros and sample code... then it will be easier to show you right way.

if-else are just blocks and not loops.
loops are those loop back till the given condition holds true.
for,while and do-while each have their own conditions checked during the iterations. Go thru the references available online or a basic java book.

This may be a dumb thing to ask, but besides the penalty for dynamic

I have made some comparision C# to Java RegularExpression. The problem was
to find out if the rule match some text.
Matching were done for precompiled regular expressions, in 100000 iterations
loop. Those loops were executed 11 times and average value of consumend time
was calculated. Below are codes for both classes.
And I found, that Java implementation is 2 to 5 times faster than C# (it
depends on complexity of expression).

Hi,
I am trying to compare the amount of work between using STL algorithm
VS a plain Java loop.
Let's say the class Rect has 2 attributes: area, and areaPerCent.
In Java, I just write a plain for loop with a list:
public static void calculateAreaPerCent(List rectList, float
containerArea) {

I need help with a program I am writing for school. The program has to do the following:
/*
1. Character string must be a minimium of 15 charactors.
2. If not 15 characters long it must give error and send you back to orginal question.
3. After entering 15 characters it must count the CAPTIAL letters and tell you how many there are.
4. Need a loop to count and produce error and take you back to first screen.

Folks,
I've a Python 2.5 app running on 32 bit Win 2k SP4 (NTFS volume).
Reading a file of 13 GBytes, one line at a time. It appears that,
once the read line passes the 4 GByte boundary, I am getting
occasional random line concatenations. Input file is confirmed good
via UltraEdit. Groovy version of the same app runs fine.
Any ideas?

Do not take anything about this, it is not a flame or troll, while I'm not
new to Java I favor C++. However, I may need to use it in a contract
position, and am concerned that the restrictions it places on application
code.
Take, for instance, this C++ construct:
class foo
{
char *m_name;

I followed a link to James Kanze's web site in another thread and was
surprised to read this comment by a link to a GC:
"I can't imagine writing C++ without it"
How many of you c.l.c++'ers use one, and in what percentage of your
projects is one used? I have never used one in personal or professional
C++ programming. Am I a holdover to days gone by?

I'm beginner at Java. I'm confused with my simple program of using while loops

item = keyboard.nextLine();
System.out.println("Enter price of " + item + " : ");

Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...

I am currently learning how to create and manage the different types of VPNs and I have a question about LAN-to-LAN VPNs.
The last exercise I practiced was to create a LAN-to-LAN VPN between two Pfsense firewalls, by using IPSEC protocols.
I succeeded, with both firewalls in the same network. But I'm wondering if it's possible to do the same thing, with 2 Pfsense firewalls...
