my logic is this.... in the part of the method ContinueOrdering()..(each code) it will ask me if i want to include the orders in the shipment... i having a hard problem with the first code so what i did is the second code..
if i enter "n" or "no" it will RESET all The VALUES of the DATA MEMBERS(field),,
or lets just say that i the method ask me
Code :
If I Want To Include THe Orders In the Shipment
and i answered no.. then it will not ADD.. (simply by reseting the value of each FIELD)..
problem:
1.) regarding with static fields , those fields as you can see is ineffient because its not a constant nor a class datamember,
2.) i want to resolve this by using the first code,, (using local variables instead of datamembers/fields)
3.) is there any method in java that can reset a value of a variable? (field or local)
4.) or one of the effient way to do this is to define a class for this program?
Re: Reset the value of each variable
This code will loop until your continueOrdering method returns false. If you have any questions, please ask.
Code :
// initialize your variables
int one = 0;
int two = 0;
while (true) {
// do your logic
if (continueOrdering()) {
// reset your variables
}
else {
break;
}
}
Re: Reset the value of each variable
I'd say if possible avoid using the while(true), for(;;) or any other type of infinite loop definition. It makes reading the code very hard and you need to be really sure about your code inside the block that it will eventually break out of it.
You might possibly run into compiler errors with unreachable code if you use these types of blocks.

Isn't that the job of the programmer to begin with?
For production code, I would say you're right if there is a case the loop might never stop. If you're just writing a toy program, then there is no harm.
Re: Reset the value of each variable
the suggestion for this is? :confused:

Did you see my first post?
To make Json happy, here's a version without an infinite loop. ;-) It is still just as "unsafe" as an infinite loop, but with different constructs.
What I am offering you is only a template. You still need to add your logic.
Code :
// initialize your variables
int one = 0;
int two = 0;
boolean run = true;
while (run) {
// do your logic
if (continueOrdering()) {
// reset your variables
}
else {
run = false;
}
}
