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...

1Arrays.sort(strArray,2(Strings1,Strings2)->s2.length()-s1.length()); In this case the lambda expression implements theComparatorinterface to sort strings by length. 2.2Scope Here’s a short example of using lambdas with the Runnable interface: ...
