How to Tag
A tag is a keyword or label that categorizes your question with other, similar questions. Choose one or more (up to 5) tags that will help answerers to find and interpret your question.
- complete the sentence: my question is about...
- use tags that describe things or concepts that are essential, not incidental to your question
- favor using existing popular tags
- read the descriptions that appear below the tag
If your question is primarily about a topic for which you can't find a tag:
- combine multiple words into single-words with hyphens (e.g. python-3.x), up to a maximum of 35 characters
- creating new tags is a privilege; if you can't yet create a tag you need, then post this question without it, then ask the community to create it for you
lang-java
Why Oracle did such a poor way to point to java is beyond meI guess the reason was that when you have relatively constant env var (pointing always to the one place - f.e.javapathfolder), you can change paths dynamically, on on the fly (changing a link does not require shell restart). While if you change env var (f.e. PATH) you'll have to restart shell to reload and apply new ENVVARs values. Sure I'm not an Oracle advocate and of course it's just my suggestion.
