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...
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....
Thefor statementin Java allows us to repeatedly loops until a particular condition is satisfied. Check this post to learnenhanced for loop (for each) Syntax: For (initialization; termination; increment){ //statement(s) } Sample Program: package ClassThreeControlFlowStatements; public class SimpleFo...
This tutorial will guide you on how to use a for loop in Java programs, perform repetitive tasks, and iterate through the elements of a collection or array. It is a core Java programming construct used to perform repetitive tasks. Contents The flow of a programSequential:Conditional:Iterative...
Java For LoopWhen you know exactly how many times you want to loop through a block of code, use the for loop instead of a while loop:SyntaxGet your own Java Server for (statement 1; statement 2; statement 3) { // code block to be executed }...
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: ...
Example 2: for loop // Program to calculate the sum of first n natural numbers // Positive integers 1,2,3...n are known as natural numbers #include <stdio.h> int main() { int num, count, sum = 0; printf("Enter a positive integer: "); scanf("%d", &num); // for loop term...
In this example, ‘int i = 1’ is the initialization, ‘i <= 5‘ is the condition, and ‘i++‘ is the iteration. Practical Application of For Loop Once you have understood the mechanics of the for loop in Java, it’s time to bring that knowledge into real-world programming. One ...

For example, if a while statement is written as follows: while (true) { . . . } The condition is simply a boolean value true. This leads to an infinite loop. The following code demonstrates the use of an infinite loop. Code Snippet: ...
