Apps :: How do I install Java?

I have downloaded Java, but when I use dpkg -i, or apt-get install, it says that it can't find the package. What am I doing wrong? I am very new to Linux, so I assume that I am doing something wrong.
Also, when I try to install LimeWire, I get this message. Can anyone help me on this too.
root@box:/home/damnsmall# dpkg -i LimeWireLinux.bin
dpkg-deb: `LimeWireLinux.bin' is not a debian format archive
dpkg:error processing LimeWireLinux.bin (--install):
subprocess dpkg-deb --control returned error exit status 2
Errors were encountered while processing:
LimeWireLinux.bin

Debian packages should end with the .deb extension.

If you are going to use dpkg, you need to make sure that your current directory is set to the directory where the *.deb file is located and it needs to be spelled exactly as it appears in the directory listing ('ls' command) including Uppercase vs. Lowercase letters.

You can install it from a different directory, but you need to specify the entire path to your deb file. IE: dpkg -i /home/damnsmall/filename.i386.deb

Good Luck.

Wait, so how do I install a .bin file on Debian?

For .bin files, you go "chmod +x (the filename).bin" then type "./(filename).bin" - that'll extract it. Then do what needs doing to the extracted file.

I tried it for my LimeWireLinux.bin, and it worked, but of course it needed Java. But when I tried it on Java, it gave me this..
root@box:/home/damnsmall# chmod +x j2re-1_4_2_04-linux-i583.bin
chmod: j2re-1_4_2_04-linux-i583.bin: No such file or directory
But thanks for showing me how to extract .bin files though.
