You’re now equipped with the knowledge you need to use Java for and for-each loops like a pro!Īt Career Karma, our mission is to empower users to make confident decisions by providing a trustworthy and free directory of bootcamps and career resources. We also discussed how each example worked step-by-step. ![]() We also referred to an example of each of these loops in action. In this tutorial, we explored how to use the for loop and the for-each loop in Java. The for-each loop is used to run a block of code for each item held within an array or collection. The for loop is used in Java to execute a block of code a certain number of times. Then, our program prints out “The new price is “, followed by the new price of the coffee. For each item in the array, our program reduces the price of the coffee by 50 cents and assigns the reduced price to the variable new_price. ![]() Then we create a foreach loop that runs through each item in the prices array. This array is declared as an array of doubles, or decimal-based numbers. Then we declare an array called prices which stores the prices for our coffees. First, we declare a class called ReducePrices, which stores our code for this example. Let’s walk through our code step-by-step. Now we have the data we need to change our coffee prices for the flash sale. The syntax for the for-each loop is as follows:Īs you can see, our program has reduced the price of every coffee by 50 cents. This is called a for-each loop, or an enhanced for loop. When you’re working with an array and collection, there is another type of for loop you can use to iterate through the contents of the array or collection with which you are working. This statement is formatted as x 10 is, followed by the answer to the problem. Then, we print out a statement with the math problem and its answer. ++i adds 1 to the i variable after the for loop has executed.i int i = 1 tells our code to start counting from the value 1.Here are the three components of our for loop: ![]() Then we create a for loop that executes the code within the loop 10 times over. Let’s explore the code and discuss how it works step-by-step.įirst, we declare a class called TimesTable, which stores our code for this program.
