Codecademy Learn Java, For Each Loop, Programming in 2018

Lesson Summary

In this Codecademy Learn Java lesson we go over the Java for each loop. The for each loop in Java is a quick way to iterate or loop through an ArrayList . The for each loop begins with the keyword "for" and then parentheses which contain a variable on the left which represents the current item of the array in the iteration we are in. Then a colon and on the right side of the colon we put the name of the array. The we end the parentheses and add our curly braces with the code we want executed between them. This code will run each time through the loop. In this specific lesson we iterate over our quizGrades array and print out each item each time through the loop.
