stapler class help

[javaLoser]

ok so here is the scoop i need to design a stapler class the addStaples method takes one argument for the number of staples but the stapler should never have more than 100 staples. the two staple methods one takes 0 arguments and the other takes an argument for how many times we staple a warning message should be printed when there are no staples left. the stapler starts with 100 staples when i run the program it gives me negative staples and adds more than 100 staples i need help im going crazy with this thing

here is my code

public final class Stapler {

public String color;

private int numStaples;




Stapler(){
color="Blue";
numStaples = 100;
System.out.prin tln("New Stapler with 100 Staples");
}

public void addStaples(int add){
System.out.prin tln("Trying to add " + add +" staples");
if(numStaples >=100){

System.out.prin tln("Can't add anymore staples!");
numStaples = add;
}
else if (numStaples ==0 ){
System.out.prin tln("Added " + numStaples + " staples.");
numStaples = numStaples + add;
}

else{
System.out.prin tln("Added " + add +" staples.");

System.out.prin tln(numStaples + " Staples left");
numStaples = add;
}
}

public void staple(){

System.out.prin tln("Trying to staple once.");
if (numStaples <=0){
System.out.prin tln("No staples left.");
}
else{
System.out.prin tln("Stapled once!");
numStaples = numStaples-1;
System.out.prin tln(numStaples + " staples left." );
}

}

public void staple(int staple){
System.out.prin tln("Trying to staple " + staple + " times" );
if (numStaples <=100){
System.out.prin tln("Stapled " + numStaples +" times");
numStaples=numS taples-staple;
System.out.prin tln("0 Staples left.");

}
else if (numStaples >numStaples){

System.out.prin tln("Stapled "+ staple +" times");
numStaples=0;
System.out.prin tln(numStaples + " Staples left.");

}

}
}

Just a reminder,

Please inclose your codes with a codetags....
Highlight your code then press the button(#) above the reply window

or add [/CODE] at the end and [CODE=JAVA] at the top of your code.

and don't double post your thread....

About your program, i don't know how your main class did the handling of that Sampler class, can you show the main class?(that controls the program) that contains a main method...

A stapler staples; it doesn't talk but more important is that your logic is flakey
here and there. A new stapler contains 100 staples. If it contains, say 40 staples
I can add 60 more staples; more simply don't fit. It is quite easy to translate these
notions to Java code:

[code=java]
public class Stapler {
public static final int MAXSTAPLES= 100;
private int staples= MAXSTAPLES; // init at construction time
//
// not really needed constructor:
public Stapler() { } // do nothing
...
}
[/code]

This is the first skeleton of the Stapler class: it contains 100 staples. Now add
a 'staple' method; it can staple one staple if it contains staples; it returns true
if it succeeded and false if it was empty:

[code=java]
public boolean staple() {
if (staples > 0) {
staples--;
return true;
}
return false;
}
[/code]

Note that it doesn't say anything, i.e. it just staples and returns whether or not
it had succeeded. An overloaded method that staples n times could look like this:

[code=java]
public int staple(int n) { // staple n staples
while (n > 0 && staple()) { // protect against nonsense values
staple(); // staple once
n--;
}
return n; // return the number of staples to do
}
[/code]

Refilling the stapler takes a bit of 101 math: when it has x <= 100 staples left
you can add 100-x more staples to it. Suppose we can't remove staples from
the stapler:

[code=java]
public int refill(int n) { // try to add n staples to the stapler
if (n > 0) { // protect against nonsense values
int newStaples= Math.min(staple s+n, MAXSTAPLES);
n-= newStaples-staples; // those didn't fit
staples= newStaples; // refill the stapler
}
return n; // return number of staples that couldn't be added
}
[/code]

You can poop up this little class a bit more by adding a getter method. You can
extend this class by a TalkingStapler that indeed tells what it's doing (that'd be
a bit of a silly stapler if you'd ask me, but feel free to add whatever you want).

kind regards,
