Install Java into browsers (Ubuntu 10.4)

[fboxall]

I have Ubuntu 10.4 with browsers Firefox and Chromium. Neither browser has Java. I want to install Java for both browsers. I have downloaded jre-6u20-linux-i586.bin and I have permission to execute it, but I don't know what folders to put it in before I execute. I need someone to educate me with detailed instructions because my computer skills are less than modest. Do I have to create folders? What is the command to execute? And so on. Any help very much appreciated.
