A contact of mine is trying to learn java programming and has started with the Herbert Schildt book Java A Beginners Guide.
His OS is Windows Vista onto which he has installed NetBeans and Eclipse.

He has asked me for help but even though I am a programmer I only use Linux so am not sure that my Vista skills are adequate other than fixing his PATH environment.
His Java version is:-
java version "1.6.0_18"
Java(TM) SE Runtime Environment (build 1.6.0_18-b07)
Java HotSpot(TM) Client VM (build 16.0-b13, mixed mode, sharing)

His 1st program is:-
[code]
/* This demonstrates a variable.
call this file Example2.java.
*/
Class Example2 {
public static void main(String args[ ]) {
int var1; // this declares a variable
int var2; // this declares another variable

var1 = 1024 // this assigns 1024 to variable 1

System.out.println("var1 contains" + var1);

var2 = var1 / 2;

System.out.println("var2 contains var1 / 2: ");
System.out.println(var2);
}
}
[/code]
but

javac Example2

error: Class names, 'Example2', are only accepted if annotation processing
is explicitly requested

How does he fix this?

BTW The above compiles and runs fine on my Ubuntu system.... Smile | :)

The javac command takes the name of the source file, not the name of the class:

I am just learning about the app montoring features available through JConsole. I am using jdk150_06 to monitor an app in development locally on a Windows PC. I set the property (-Dcom.sun.management.jmxremote) on the statup of my app jvm. I run JConsole, the JConsole comes up, sees the JVM, I connect to it and everything seems ok. I want to pull a heap dump of the app to look at in the Memory Analyzer plugin tool available in Eclipse 3.5. According to all the doco I see in JConsole I should see a "com.sun.management" MBean registered in which I can specify a location for the heap dump and generate one. However, I don't see a "com.sun.management" MBean in my JConsole.

Wondering if anyone has done this before? Am I looking for the wrong thing? Is it maybe my JDK version or something?

Any help is appreciated.

Thanks,

Troy

How to store double values in color3f?

002comp12-Jan-10 23:04

Re: How to store double values in color3f?

12-Jan-10 23:04

Hello Friends
I am getting some floating values in double.
but color3f class takes only int.
And i want to pass only that floating values.
Is it possible?

Thanks In Advance.
Regards
Yogesh

Re: How to store double values in color3f?

You cannot pass a float value to a method that takes an int as it will not handle it correctly. The only way to process this is to convert the value to an integer using whatever roundings necessary for the method to have meaningful values.

Are you sure? According to the javadoc for Color3f:

A three-element color value represented by single precision floating point x,y,z values . . . 
Color components should be in the range of [0.0, 1.0]<pre>
