Java While Loop
A block of code can be run by a loop as long as a predetermined condition is met.
Loops are useful because they eliminate errors, save time, and improve readability of programming.
Java While Loop
A block of code is iterated through by the while loop as long as a particular condition is met:
Syntax
while (condition) {
// code block to be executed
}
In the example below, if a variable (i) is less than 5, the loop’s code will continue to run repeatedly:
Example
int i = 0;
while (i < 5) {
System.out.println(i);
i++;
}
Note: If you don’t increment the variable in the condition, the loop will never stop!
