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 }...
As mentioned in syntax, theinitialization, termination, and increment are optional parts, that can be controlled from other places. Or the for loop might not have all of them. For example, we can rewrite the previous example as below. We have taken out thecounterinitialization before the loop...
Kotlin for Loop There is notraditional for loopin Kotlin unlike Java and other languages. In Kotlin,forloop is used to iterate through ranges, arrays, maps and so on (anything that provides an iterator). The syntax offorloop in Kotlin is:...

Statements outside the loop cannot referenceindex. Statements inside the loop...
Learn how to use the Java for loop to iterate over arrays and collections efficiently. Discover syntax, examples, and best practices for optimizing your code.
Meaning, the loop terminates if the statement expression/ condition becomes false. This structure allows programmers to control the flow of their code and perform repetitive tasks with ease. Syntax Of For Loop In C++ for (initialization; condition; increment/decrement) {// code to be executed} ...
Another common control flow is a loop. Go uses only one looping construct, and that's aforloop. But you can represent loops in more than one way. In this part, you'll learn about the loop patterns that Go supports. Basic for loop syntax ...
You can omit expression 1 when your values are set before the loop starts: Example leti =2; letlen = cars.length; lettext =""; for(; i < len; i++) { text += cars[i] +""; } Try it Yourself » You can intiate many values in expression 1 (separated by comma): Example...
InputStream is = LoopElimination.class.getResourceAsStream("/testfile.txt"); // while loop with clumsy looking syntax int c; while((c = is.read()) != -1) { System.out.print((char)c); } // But this is even uglier InputStream nis = LoopElimination.class.getResourceAsStream(...
For each.This is a simple syntax form. If we loop over a collection, we use a colon, not an index variable. This enumerates each element in the collection (array, ArrayList).Array Info:This is called a foreach-loop statement. The Java language does not support a "foreach" keyword. ...
