i.e the counter is always increased by one, whereas in for loop you can change the step as per your wish e.g. The syntax of the for-loop is: Here the initialization expression is executed once before the first iteration of. We can use a simple for-loop in Java to iterate over a range of values. Let’s explore each one of them in detail: 1. Either we know exactly how many times the loop will be executed or we have a better idea than "until n becomes m". 2) The enhanced for loop executes in sequence. There are two types of for-loops in Java: Simple for-loop and enhanced for-loop (for-each loop). But in enhanced for loop we get hold of the row, and for each row we get the values of elements. In the traditional method, we dealt with the index and fetched elements.
In Java, there are several ways to control the flow of the code:įor loops are typically used when the number of iterations is "fixed" in some way. The For-Each loop is usually used as a substitute for the standard for-statement when a loop counter is not really needed, and every element in the collection.

Loops were a concept used long before computer programming was even a thing, but the first person to use a software loop was Ada Lovelace, commonly known by her maiden name - Byron, while calculating Bernoulli numbers, back in the 19th century. low-level programming languages usually achieve that affect with a lot of go-to commands.
Every programming language supports some form of flow control, if not explicitly via ifs and fors or similar statements - then it implicitly gives us the tools to create such constructs, i.e. That's what "flow control" means - guiding the execution of our program, instead of letting it execute line-by-line regardless of any internal or external factors. There aren't many things we could do with code that can only execute line-by-line. Conditional statements and loops are a very important tool in programming.
