In the circle example why are we using %d for diameter and %f for area and circumference? What is the difference between %d and %f.Also on the search code i tried following the steps you gave but i encountered and error message on this line (int index =0;)as it says the assigned value is never used.What that mean and how do i go about solving that problem.

	0 answers Post by Donna Parcel on February 1, 2013 Can you tell me what I'm doing wrong--I downloaded the 4 programs circle, search, find&replace, and calendar and tried to run them in JCreator, NetBeans and they won't run -- I get all kinds of errors. Thanks Donna
	0 answers Post by anuj singh on January 20, 2013 I am getting error with the dot operator when i try to compile the calendar program on dos what can be the possible reason ?
	0 answers Post by Harlan Reece on December 30, 2012 I tried running the circle program through Netbeans with partial success. My compile was successful, but I did not see a prompt to enter data in the output window. In addition to this problem, I do not see an option to set as Main project option. Is there a preference option where I can set this. When I type enter my project name, it does not simultaneously provide a .Main extension in the Create Main Class field as it does in the video, but rather creates an extension with the exact same name as the project file. What am I doing wrong. Had absolutely no success in running program from DOS prompt. What am I doing wrong?

	1 answer Last reply by: Loammi Pedroza Tue Apr 16, 2013 8:36 PM Post by Kwasi Roberts on March 29, 2012 On line 13 on the "Find and Replace" section can you explain tht whole line especially text.replace please?
	0 answers Post by Thomas James Hanrahan on September 29, 2011 Because for some reason the java.util.Calendar; causes the output to be one month behind. I guess that is why you always try to "Break" your code once its complete so you don't run into problems like this. with +1 Today's date is;9-29-2011 Tomorrow's date will be: 9-30-2011 Without +1 Today's date is;8-29-2011 Tomorrow's date will be: 8-30-2011
	2 answers Last reply by: alina trandafir Sat May 23, 2015 7:31 PM Post by Alvaro Lacerda on September 7, 2011 On the 10th line of the calendar program, why do you add "+1" after the "(Calendar.MONTH)"? why that doesn't happen to the other lines "(Calendar.DATE)" and "(Calendar.YEAR)" ? Thanks,

Working with Java

Java was developed in 1990 by Sun Microsystems
Java was based on C++ syntax
Java requires both the Java Runtime Environment (JRE) and the Java Development Kit (JDK) to be downloaded and installed from www.java.com
Programming in Java follows a two-step process of writing code in a .java file, then compiling that code into a .class file
Programs often take advantage of built-in imported utility classes such as the “Scanner” class which allows user input
