Spring
Spring is a popular toolkit for building business software using Java programming language. Think of it like a construction kit that comes with pre-made building blocks, making it easier and faster for developers to create business applications. It's particularly known for helping create enterprise-level software - the kind large companies use for their daily operations. Similar to how Microsoft Office is a collection of useful tools (Word, Excel, etc.), Spring is a collection of tools that developers use to build complex business applications more efficiently. When you see Spring mentioned in a resume, it usually indicates the candidate has experience building professional-grade business software.
