CollectionUtilsisNotEmptycoll

CollectionUtils isNotEmptycoll is a method found in various Java utility libraries, most notably Apache Commons Collections. Its primary purpose is to check if a given collection is not null and contains at least one element. This is a common operation in programming to avoid potential errors like NullPointerExceptions or to simply determine if there is data to process.

The method typically takes a single argument, which is the collection to be checked. It returns a boolean value: true if the collection is not null and its size is greater than zero, and false otherwise. Some implementations might also consider an empty collection (one with a size of zero) as not "isNotEmpty," aligning with the method's name.

The utility of CollectionUtils isNotEmptycoll lies in its ability to simplify conditional logic. Instead of writing multiple checks like if (myCollection != null && myCollection.size() > 0), developers can use this single method call. This improves code readability and reduces the chance of logical errors. It is frequently used in loops, data validation, and before attempting to iterate over or access elements within a collection. The specific package and exact method signature might vary slightly depending on the library version or alternative utility classes, but the core functionality remains consistent.
