Install Multiple Java Versions on macOS High Sierra

Install Homebrew Cask

On Mac, Homebrew is the de-facto package manager, and Homebrew Cask is the app manager. I’m going to use Cask to install Java 7 and 9.

Install Homebrew Cask first if you haven’t:

brew update
brew tap caskroom/cask

How to draw a gradient border button?

My Problem

Last week, my partner showed me his design for our application. Everything is great, easily implemented with some custom controls. But wait, something is not in my knowledge.

A button with gradient border. Never try it before. Up to now, I just created gradient background views 2 times in previous projects. Googled and found some good results.
