Iteration

Iteration and Collection Interface In Java, iteration refers to the process of accessing elements of a collection in a sequence. The Collection Interface is a root interface for all collections in the Java Collections Framework. It provides the basic functionality that all collections share, such as adding, removing, and checking elements. Collection Interface The Collection interface is part of the Java Collections Framework and defines the common methods used to work with collections of objects. Some of the key methods defined in the Collection interface include: ...

Iteration Iteration in Java refers to the process of iterating or traversing through a collection (such as a List, Set, or Map) to access its elements. Iteration is a crucial aspect of working with collections in Java and can be performed using various techniques like for, while, do-while loops, and using the Iterator interface. Iterating Over Collections Using Different Methods Using For-each Loop: The simplest and most concise method of iterating over collections. List<String> names = Arrays.asList("Alice", "Bob", "Charlie"); for (String name : names) { System.out.println(name); } 2. **Using Iterator**: * The `Iterator` interface provides methods like `hasNext()` and `next()` to iterate through the elements in a collection. ```java Iterator<String> iterator = names.iterator(); while (iterator.hasNext()) { System.out.println(iterator.next()); } Using forEach Method (Java 8+): ...
