| Excerpt |
|---|
Statements provide a convenient method to execute conditional or repetitive operations. The syntax is C/C++/Java like, so things should be easy to grasp. |

if (isNotNull(fixVersions) and affectedVersions == {"1.1"})
{
affectedVersions = {"1.1", "1.0" , "1.2"};
fixVersions = {"1.2" , "1.2" , "1.3"} ;
}
else
{
affectedVersions = {"1.1"};
fixVersions = {"1.0"};

For Statement
The for statement provides a compact way to iterate over a range of values. Programmers often refer to it as the for loop because it repeatedly loops until a particular condition is satisfied.

While Statement
The while statement offers support for repeated executions. This form evaluates the condition first and then executes the instructions in the body.
...
- inside a loop (for, while): when encountering the break, the execution of the loop is terminated and the control is transfered to transferred to the statement that follows the loop;
- in switch statements: when a case is followed by a break, it does not execute subsequent cases and control is transferred out of the switch statement.
