1. Overview
In this article, we’ll look at a core aspect of the Java language – executing a statement or a group of statements repeatedly using a while loop.
2. While Loop
The while loop is Java’s most fundamental loop statement. It repeats a statement or a block of statements while its controlling Boolean-expression is true.
The syntax of the while loop is:
while (Boolean-expression)
statement;The loop’s Boolean-expression is evaluated before the first iteration of the loop – which means that if the condition is evaluated to false, the loop might not run even once.
Let’s have a look at a simple example:
int i = 0;
while (i < 5) {
System.out.println("While loop: i = " + i++);
}3. Conclusion
