In a recent article, I reviewed some of the differences between creating and initializing maps in Groovy<\/a> and doing the same thing in Java. In brief, Groovy has a concise syntax for setting up maps and accessing map entries compared to the effort necessary in Java.<\/p>\n

This article will delve into more differences in map handling between Groovy and Java. For that purpose, I will use the sample table of employees<\/a> used for demoing the JavaScript DataTables library. To follow along, start by making sure you have recent versions of Groovy and Java installed on your computer.<\/p>\n

Install Java and Groovy<\/h2>\n

A recent and\/or decent version of Java and Groovy might already be in your Linux distribution’s repositories, or you can download and install Groovy from the Apache Groovy website<\/a>. A good option for Linux users is SDKMan<\/a>, which can be used to get multiple versions of Java, Groovy, and many other related tools. For this article, I’m using SDK’s releases of:<\/p>\n
