To iterate over elements of String Array, use any of the Java Loops like while, for or advanced for loop. The index of string array starts from 0 to array length – 1. We can use this information and write a loop to iterate over string array elements. In this tutorial, we will learn...
Since version 8, Java has introduced theStream APIand lambdas. Next, let’s see how to iterate a map using these techniques. 5.1. UsingforEach()and Lambda Like most other things in Java 8, this turns out to be much simpler than the alternatives. We’ll just make use of theforEach()...

Summary,If you need only keys or values from the map, use method #2 or method #3. If you are stuck with older version of Java (less than 5) or planning to remove entries during iteration, you have to use method #1. Otherwise use method #4....
Object[] namesArray = names.toArray();for(inti=0; i < namesArray.length; i++) { System.out.println(i +": "+ namesArray[i]); }Copy Mind that conversion to an array alone will iterate over theSetonce. So, in terms of complexity, we’ll be iterating over theSettwice. That may...

The created iteratee will return Done with the computed A when an input EOF is pushed.One example would be creating an iteratee that counts the number of bytes pushed in:val inputLength: Iteratee[Array[Byte],Int] = { Iteratee.fold[Array[Byte],Int](0) { (length, bytes) => length + ...
