[Term Entries] Java Math Methods: `.max()` and `.min()`

[Dusch4593]

Reason/inspiration (optional)

Under java/concepts/math-methods/terms/, create a new term entry for the Math.max() and Math.min() Java methods.

• In the terms/ folder, make new folders called max and min.
• Inside the max and min folders, create a new markdown file called max.md and min.md, respectively.
• Inside the file, be sure to include a "Syntax" section with a ```pseudo code snippet.
• Also make sure to include an "Example" section with a ```java code snippet.

Please refer to the entry templates, content standards, and markdown style guide when working on the PR for this issue.
