Loops

Apex supports the following five types of procedural loops:

• do {statement} while (Boolean_condition);
• while (Boolean_condition) statement;
• for (initialization; Boolean_exit_condition; increment) statement;
• for (variable : array_or_set) statement;
• for (variable : [inline_soql_query]) statement;

All loops allow for loop control structures:

• break; exits the entire loop
• continue; skips to the next iteration of the loop
