Chrome does have Plug-Ins which includes programs such as Java from Sun Microsystems, Acrobat from Adobe. Enter about:plugins on the address bar, it will list the plug-ins that are available in Google Chrome. Here's a list:
The Flash plug-ins doesn't embed by default. You can visit Adobe Flash Player website to install it.
If you're a Chrome user, enter chrome://plugins into the URL bar, and make sure Java is unticked. The process for Firefox users is a little easier: Go to Tools > Add-ons> Plugins and disable Java from there. IE users should click on the gear icon at the top right of the browser, select Internet Options > Programs > Manage Add-ons and make sure that the Java Plug-Ins listed are disabled. If you're a Safari user, it's quite likely Java's already disabled (Apple did so in a recent update), but just to be sure, go to Preferences > Security and make sure Java is unticked.
