Over the period, Java has added different types of for loop. for loop repeatedly loops through the code until a particular condition is satisfied. It automatically increments by 1 and we cannot specify the same We can access array elements based on index value We cannot access elements based on index value Able to iterate forward and reverse direction Able to iterate only in forward direction Available from JDK 1 onwards Available from JDK 5 onwards Can be used for any type like integer,strings, collection, array Can be used only for array and collection type. Java for loop and enhanced for loop is a type of control flow statement which provides a compact way to iterate over a range of values. For Loop For-each loop Executes based on the condition mentioned within for loop Does not have any condition specified We can specify the increment or decrement counter variable. The below table shows the major differences between for loop and enhanced for loop. This is actually only syntactic sugar for getting an iterator from the object and using. In the previous tutorial, we have learned about for loop. In this tutorial, we will learn about the Java for-each loop and its difference with for loop with the help of examples. Classes implementing Iterable<> interface can be used in for loops.We can have any number of loops one inside the other. The difference between do-while and while is that do-while evaluates its expression at the bottom of the loop instead of the top. Examples and practices described in this page dont take advantage of improvements introduced in later releases and might use technology no longer available. We will explore this iteration statement along with the syntax and programming examples. That is, the inner loop will begin and end inside the outer loop. The Java Tutorials have been written for JDK 8.
