My first guess would be that she is too young for Java. Why don't you start with a more modern languages like NodeJS or Python? Those languages are easy to start and are not that overwhelming like the languages that carry too much legacy.
For the editor I'd recommend Visual Studio Code. Its open sourced and comes with tons of addons for the languages of your choice. What Microsoft can do really well - is to build great IDEs.
There are tons of books online, check in amazon for best sellers. Another options is video courses. They again are more easy to start with. There is udemy, skillshare, coursera. This format is more interactive. With video lessons chances are much higher she will not get bored and would continue with this further.
my 2 cents.
