![]() ![]() The foreach loop automatically counts the number of elements in the array and iterates through them.The foreach loop is used to loop through collections or arrays.The for loop must specify its counter and the increment/decrement of that counter in the condition block of the statement.The for loop is used when we know how many times a loop should repeat.The do while loop is used when we don’t know how many times a loop will repeat, but it should be at least once.The while loop is used when we don’t know how many times a loop will repeat.Java provides us with while, do while, for and foreach (enhanced for) loops.Iteration control allows us to repeat sections of our code by looping through them.For that we would need to nest our loops. We would need to create blocks in each of the three axes, x, y and z. We want it to be 16 x 16 blocks on the x and z axes (creating a square), and we want it to be 16 squares high on the y axis, creating a tower (chunk). The loops will be executed hierarchically, which means the compiler will run an inner loop fully, before it moves on to the next iteration of the outer loop.Īs an example, let’s consider that we want to create a chunk of blocks like those in Minecraft. Similar to nesting conditional control statements, we can nest loops inside other loops. In the example above, we iterate through an array with 4 elements, which the loop automatically calculates.īecause the values in the array are strings, our temporary variable ‘i’ has to be a string type too. This continues until i is 10, in which case the condition turns false and the compiler stops looping.The condition is still true because i, now 2, is still less than 10, so it executes the code block again. Then, it will move back to the start of the loop and evaluate the condition again.This means the loop condition is true, so it will print the message to the page and increment i by 1. We also increment it by one by adding ++ to it. In the code block we have a simple statement that prints the number i.While the value of i is less than or equal to 10, execute the code in the code block. This variable will act as a counter, and help us see which iteration of the entire loop we’re on. First, we set up a variable called i with the number 1.Let’s break down the example above step by step. The single section of code we wrote in the code block was repeated 10 times. foreach - This loop is specific to loop through collections.for - This loop iterates through a section of code a set number of times. ![]()
