Java / Control Statements

What types of loops does Java support?

Java offers three different types of loops: for, while, and do-while.

A for loop provides a way to iterate over a range of values. It’s most useful when we know in advance how many times a task is going to be repeated.

for (int i = 0; i < 50; i++) {
     // do something 
}

A while loop can execute a block of statements while a particular condition is true.

while (iterator.hasNext()) {
    // ...
}

A do-while is a variation of a while statement in which the evaluation of the boolean expression is at the bottom of the loop. This guarantees that the code will execute at least once.

do {
    // ...
} while (i != -1);
