Run it differently

Posted by Shankar on October 02, 2001 at 3:04 AM

> I have a very silly question. Let's say I have two classes. One named TextReader.java and the other named LeapYear.java. Let's also say that LeapYear.java creates a new instance of TextReader named keyboard. Both of these files reside in the same folder. There are no defined packages. When I run my code in JBuilder, it runs perfectly, no errors. I can compile TextReader from the command prompt (with javac) with no problems. When I try to compile LeapYear from the command prompt with javac, I get the following error:

> C:\test>javac LeapYear.java
> LeapYear.java:7: cannot resolve symbol
> symbol : class TextReader
> location: class LeapYear
> TextReader keyboard = new TextReader();
> ^
> LeapYear.java:7: cannot resolve symbol
> symbol : class TextReader
> location: class LeapYear
> TextReader keyboard = new TextReader();

> If both of these files are located in the same folder, why can't javac find TextReader? This seems like such a simple thing, I must be missing something obvious.

Hello,
This problem is because of JBuilder. As the previous reply from MFG says, when u write a program in JBuilder,it automatically creates a pakage and stores it in that package. U can also see in ur program(s) when openend in JBUilder that the package name will be written.
So, u have 3 opions.
1. Write the code in pure java(out of JBuilder, in notepad / any editor) and run them. This will defintely run.
2. Compile and run the applns in JBuilder. Dont compile in JBuilder and run in prompt.
3.Compile in JBuilder and u can run it from Command prompt by going out of the package path and running:
Ex: If the program(s) are in c:\temp\bin\LeapYear.java & c:\temp\bin\TextReader.java, then compile in c: as

c:\javac temp\bin\TextReader.java
c:\javac temp\bin\LeapYear.java
It will succeed
Also run as
c:\java temp.bin.TextReader
or
c:\java temp.bin.LeapYear
