JAVA NEWBIE

Posted: Jan 24, 2006 8:35 AM

I'm so glad I found this site. I could really use some help and guidance on JAVA. I just started a class "Intro to JAVA Programming" and have no programming background. I know how to turn on a computer, abuse it, crash it and turn it off (I actually know a little bit more than that, but trust me.... not much more, LOLL).
I would really appreciate some suggestions as to what publications, websites etc. are out there for complete novices to the world of JAVA. I have been searching all over the net for answers to questions.
Such as:
How does a JAVA program get into executable format?
What is the command to compile a JAVA program?
What is the command to view the result of a compiled JAVA Cdoe?
How do you comment a line in JAVA?
How do you comment several lines at a time in JAVA?
Trust me I could go on and on. If anyone out there has a good source to locate these answers I would be greatly appreciative for your time and help.

I will try to answer most/all of your questions, please post again if I need to clarify anything further.

>How does a JAVA program get into executable format?
This is asked quite regularly here, I believe it has been asked three times this month already. Please look at some of the older posts here, I do not believe you will have trouble finding an answer to this question.

>What is the command to compile a JAVA program?
The most basic command is just javac HelloWorld.java, where HelloWorld.java is the actual name of your source code. Be aware that javac is case sensitive on the file names, and your class name and file must match exactly!

>What is the command to view the result of a compiled JAVA Cdoe?
Do you mean run the resulting file that was compiled/interpreted or actual viewing the contents?

How do you comment a line in JAVA?
How do you comment several lines at a time in JAVA?
>// is used to comment a line, where /* and */ are used to comment multiple lines.

JAVA NEWBIE Question

Posted: Jan 31, 2006 9:40 PM

public class IfElseDemo {
public static void main(String[] args) {

int testscore = 76;
char grade;

if (testscore >= 90) {
grade = 'A';
} else if (testscore >= 80) {
grade = 'B';
} else if (testscore >= 70) {
grade = 'C';
} else if (testscore >= 60) {
grade = 'D';
} else {
grade = 'F';
}
System.out.println("Grade = " + grade);
}
}
This is the output from the program.
Grade = C

what if.. i want to put myself a testscore and not by default as it was in above testscore = 76;... how change it?
tnx
