13 paź 2020 · The Java Set interface represents a collection of objects where each element in the Java Set is unique. In other words, the same element cannot occur multiple times in a Java Set. This Java Set tutorial explains how the Java Set interface and its implementations work.
Learn how to use the Set interface in Java to create and manipulate sets that do not contain duplicate elements. See the methods, operations and classes that implement the Set interface, such as HashSet, TreeSet and EnumSet.
