Why is it necessary to install Android Studio or JDK (please explain what they are) to learn Java?

Question

I don't have computer personally but have access to my friends' computer for 1 hr daily and I think I could use that time to learn Java. But I can't take a risk of messing up his system by trying to install those programs. Is there a way I could learn Java without installing anything on computer like html?

Answer 1

Android Studio is used to create android app but I don't suggest you to start with android. JDK (Java Development Kit) is used to compile your java program so you can execute them. You can't really do much without it but still you can search for a web executor (a website that execute your java code and print the output) like SoloLearn. It's less powerful and you can't learn everything but it's better than nothing

Answer 2

U could you Java SE for learning java and making simple apps,then letter when you have become better you can install JDK,, U could use IDE's like eclipse,netbeans,intelliJ,Dr java....
