Java

OOP and most design patterns are useless.

Better learn data structure so you can easily switch between numerous languages.

Language is not important try focus on grammar.

it"s good to learn java and OOP design pattern but don't stick to it don't worship java just learn it for it's rich oop and after that just look for what are u willing to build if it's a web app ? maybe try learning javascript and nodejs it's easy if u already now java cuz javascript it"s easy even tho u might find it bit creepy but it's good for web these days check some of it's stacks MERN,MEAN ... if you are willing to build some AI projects maybe python would fit what u are looking for don't learn programming languages just learn technologies and use them as tools
 
I think all high volume environment migrate to Golang still Java could work depending on what you are doing but I can't image what.
I remember uber moved some part of its code to golang to handle enormous number of requests per second.
 
Internet. A good example is here

I don't think you read but that guy have clearly written it's a "small bank" and the review is from 2015 and even if they run msdos - that's just 1 bank in 1 country.
 
Design principles are not mandatory and OOP failed many except you their is no misinformation whatsoever papitio.

Several of your replies here are downright spreading disinformation.

I assume you're just trying to help, but you're giving out too many bad tips. OOP failed? WTF? Several other infos you gave are way innacurate.

I think you've never been into a bank. There are plenty of large banks out there (atleast in Europe) using MS-DOS. It offers the exact functionality they need, and nothing else.
 
Their is no misinformation it's how internet works you don't find this kind of information on a blog rather look in paper written 20 years ago.

Your reaction that I'm spreading misinformation remind me of people who found out face mask don't protect against Corona after two weeks.

Do your research and look around but don't make statement that are not true.
