1.3EditPlus
EditPlus is a small but powerful text editor produced by South Korea's Sangil Kim. Friends can use EditPlus to complete all the text editing functions you want. EditPlus is also a very easy-to-use HTML editor, which supports C, C++, Perl, Java. The EditPlus software has a built-in complete HTML & CSS1 command function
(Since it has been uninstalled, the screenshot will not be shown.)
When I first learned Java, I used an IDE. Later, when I came to school, my teacher used EditPlus to teach. Then I came into contact with VS code. Now I learn Android. Java only needs to learn basic syntax. I recommend using vs code and developing Android later. I will use AS Android Studio, which is a professional Android native development tool. Now practicing Java syntax and using vs code is enough. Of course, our code demonstrations are all carried out with IDEs. Who makes me like that cool interface?
