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.
No, Java is a completely safe program from Oracle Software. Plus, Java comes preloaded on all computers, so therefore it is safe.
Yes
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.
i Would say it because when i used to use it it would run slow and i got a warning from java
