Iteration

Java has three different control structures that allow the computer to perform initiative tasks: for loop, while loop, and do ... while loop

The for loop

The general form of a for loop is

for (initialization; termination condition; update statement) {
  statements // body of loop
}

The termination condition is tested at the top of the loop; the update statement is performed at the bottom

Example

for(int i = 1; i < 5, i++) {
  System.out.print(i + " ")
}
//outputs: 1 2 3 4
