Where is java.util.Scanner?

pda_h4x0r · 08-25-2006, 12:22 AM

Hello everyone,

I'm in a java class and I'm trying to do my homework on my linux machine. However, the class Scanner in java.util is nowhere to be found! Can anyone tell me where it could be (or where it could be downloaded)?

Thank you

Hi -

Make sure you have the Sun JDK 1.5: java.util.Scanner wasn't available in 1.4.x or any earlier release:

That explains it--I was using 1.4.2.

Thank you

I can't get this class(java.util.Scanner) to work. I have:

java version "1.5.0_06"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.5.0_06-b05)
Java HotSpot(TM) Client VM (build 1.5.0_06-b05, mixed mode)

Got any answers?
Thanks!

Hello,

I have the same problem.

When I issue java -version I get:

Code:

rug@rug-lap:~$ java -version
java version "1.5.0_13"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.5.0_13-b05)
Java HotSpot(TM) Server VM (build 1.5.0_13-b05, mixed mode)

I'm using Eclipse. I've changed the compiler compliance to 5.0. How should I go about debugging this problem.

Any help is appreciated.

Thanks,
vxc

Ok I did some digging around.

I found out that I have to issue the following to make sure Sun's version of Java is being used instead of GCJ:

As root:

Code:

update-java-alternatives -s java-1.5.0-sun

Then make sure that in /etc/jvm that the following line is on top:

Code:

/usr/lib/jvm/java-1.5.0-sun

Then in /etc/eclipse/java_home edit the file and make sure the following line is on top:

Code:

/usr/lib/jvm/java-1.5.0-sun

The above applies to ubuntu but it should work for most 'endians.

HOWEVER, this didn't really stop the error. Eclipse still says it cannot resolve java.util.Scanner.

Thanks again for any help,
vxc

Ok ok I got it to work. On Eclipse, you need to go to Project>Properties then click on the Library tab and add the JRE Library as in /usr/lib/jvm/java-1.5.0-sun/jre.

Hope that helps for anyone who comes down this path.

Cheers,
vxc
