Java is a general purpose programming language that is commonly used for building web services, APIs and enterprise business applications. Such applications often need to impose strict policies on the operations they perform and the data they process. Java is also commonly used in domains that are highly regulated, such as finance, healthcare, and government where enforcing policies is even more critical.

These domains often come with complex policies to encode and enforce. When doing so, Java code can become verbose and difficult to maintain. This guide shows some examples of policy code in Java and the corresponding Rego code for comparison.
