Your English vocabulary is way better than mine: I didn't even know what
'chickweed' was, I had to look it up. Do you want to show their image on the
screen? Have you looked at the Icon and JLabel classes?

kind regards,

hoo hii!
thanks alot (for your quick asnwer)...
well i havnt looked there yet, and mmm yes i mean to show their picture on the screen i belive that for the picture itself i just need to use "*"... but the problem is how can the user trace their amount??
i thought that i can use a loop, (for loop):

bla bla bla bla...... // The lines before my main example LOL
int amount;
amount = info.nextInt();
for (i=0;i<amount;i++)
{
System.out.print("*");
}
am i wrong??

actually i "came" from the Macromedia/Adobe "flash world", so my ActionScript is perfect but Java is annoing!! (LOL :))

Of course you can if you want. Just try to wrap the code in code tags when you do so.

P.S Changed the thread title.

hye everyone...
well,here is one of my first Java applications:

import java.util.Scanner;
public class Card
{
public static void main(String[] args)
{
    Scanner info = new Scanner(System.in); 
    int i; 
    int amount; 
    String name; 
    String nameLast; 
    int phone; 
    String adress; 
    int adressNum; 
 
    System.out.println("please insert your first name");
    name = info.next(); 
 
    System.out.println("please insert your last name");
    nameLast = info.next(); 
 
    System.out.println("please insert your phone number");
    phone = info.nextInt(); 
 
    System.out.println("please insert your adress");
    adress = info.next(); 
 
    System.out.println("please insert the number of your house");
    adressNum = info.nextInt(); 
 
    String nameAndLast = "My name is: " + name + " " + nameLast;
    int nameAndLastName = nameAndLast.length(); 
 
    System.out.println(nameAndLast);
    System.out.println("phone number: " + phone);
    System.out.println("Adress: " + adress + " " + adressNum);
 
    amount = nameAndLastName + 3; 
 
 
    for(i=0;i<amount;i++)
    {
    System.out.print("*");
    }
 
}
}  

do you have suggestion for making this clumsy script shorter??

thanks alot!
mike

Does it work? Did you try to compile and run it?

kind regards,

Jos

[mike131]

ohh yes! i forgot to say :)
it works perfectly!

You can start by declaring variables closest to where they are used.
Why do

String name; 
....
name = info.next(); 

When you can simply do

String name = info.next(); 

That "declare all variables first" is only required in C. In Java you can declare variables as and when you need them.
That should make the code considerably shorter.

[JosAH]

Also, instead of cramming everything in one single method think of separate
methods that do just one single task, i.e. instead of the statement combination
for prompting the user for something:

System.out.println("please insert your first name");
name = info.next(); 
 

Think of something like this:

String prompt(Scanner scanner, String prompt) {
   System.out.println(prompt);
   return scanner.next();
}
...
name= prompt(info, "please insert your first name");
 

This won't necessarily reduce the line count of your code but it certainly structures
the functionality of it all quite a bit more.

Jos
