What is the difference between 'openjdk-headless', 'openjdk', 'openjdk-devel' packages ?

Issue

• I found 3 different kinds of OpenJDK packages such as 'openjdk-headless', 'openjdk', 'openjdk-devel'.
• What is the role of each package?
• When I tried to install OpenJDK with yum, it seems that some dependencies were found like the below.

$ sudo yum install java-11
