Yes
No, Java is a completely safe program from Oracle Software. Plus, Java comes preloaded on all computers, so therefore it is safe.
The Java plug-in for the Java Runtime Environment (JRE) is safe for your computer in most cases. The Java company regularly tests for safety and security, so if a problem is detected a patch fix is released immediately.
Yes - if you download the java installable from suns original website and not from any suspicious website.
Safe is an extremely relative term. If you mean safe as in people can't see your source code... .class files that JAVA creates are easy to decompile and look at the source code of, and .jar files are nothing more than .zip files. For safety from screwing up something bad in the program, java is generally safe and protects the programmer from accidentally reading an area of memory they don't have access to, etc. (memory management, garbage collector is done for you). If you mean safe as in safe to program in and learn, that Java won't go out of fashion any time soon, then it is very safe, as Java, as it updates, tries very hard to retain support for programs written in older versions of Java, and Java is not going anywhere anytime soon, it is a major language with over 3,000,000 devices running it.
yes but it doesn't work very fast
Yes. If you download it from the official site, there should be no problem.
I bought some ice java awhile ago and notices it has an exp. date of jan., 2009. Is it safe to consume?
So long as they're from a legitimate site - yes. Many programs on your computer use Java. Periodically, as with other software, Java gets updated. You will always have the option to refuse an update but, so long as it's an update for a program you already have, it will be safe to accept.
Java itself is 100% safe to have installed on your computer. Programs written in Java, however, may still harm your computer. Always look for user reviews before running ANY unknown program on your computer.
nobody will ever no
None that are legit. None that are safe.
Yes - that's the standard program used to run programs written for the Java technology. Just be sure you get the real Java download, and not some fake - in other words, download from the official Java site, or from a reputable site such as tucows, download.com, etc.
