This is a simple example of for loop. Here we are displaying the value of variable i inside the loop body. We are using decrement operator in the loop so the value of i decreases by one after each iteration of the loop and at some point the condition i>1 returns false, this is when...
5. When should I use a for loop versus a while loop in Java? Use a for loop when the number of iterations is known or when iterating over a range of values. On the other hand, use a while loop when the number of iterations is uncertain or when looping based on a condition that ...
Note that all expressions in thefor-loopare optional. In case, we do not provide theterminationexpression, we must terminate the loop inside the statements else it can result in aninfinite loop. 2. Java For-loop Example In the following program, we are iterating over an array ofintvalues....
To demonstrate a practical example of the for loop, let's create a program that counts to 100 by tens:ExampleGet your own Java Server for (int i = 0; i <= 100; i += 10) { System.out.println(i); } Try it Yourself » In this example, we create a program that only print ...
迭代是所有编程语言中最基本的要求之一,而“ for”是Java中迭代次数最广泛使用的循环。 我们将看到Java for循环迭代技术的发展。 (Java for loop Evolution) We will work on an example for displaying names of actors from aCollection. For the sake of simplicity let’s take aListand set this up: ...
For example, when looping over an array of numbers you will need to loop over as many times as there are elements in the array. For Loop Structure Java for loops are structured to follow this order of execution: 1) loop initialization 2) boolean condition – if true, continue to next ...
4) Iterating through a String array: Before Java 5 Before Java 5, the way to loop through an array involved (a) getting the number of elements in the array, and then (b) looping through the array with a for loop. Here’s a complete source code example that demonstrates the syntax pr...
As shown in the code, the value of count is always 0, which is less than 100. So, the expression always returns a true value. Hence, the loop never ends. A break statement can be used to terminate such programs. Thus, it will just go into the loop once and terminate, displaying th...
In this tutorial, we explored how to use the for loop and the for-each loop in Java. We also referred to an example of each of these loops in action. We also discussed how each example worked step-by-step. You’re now equipped with the knowledge you need to use Java for and for-...
