当特定代码段应以所需的迭代次数进行重复时，将使用循环。 Apex支持传统的for循环标准以及其他高级循环类型。在本章中，我们将详细讨论Apex中的Loops。
循环语句使我们可以多次执行一个语句或一组语句，以下是大多数编程语言中循环语句的概述-
下表列出了处理Apex编程语言中循环要求的不同循环。单击以下链接以查看其详细信息。
| Sr.No. | Loop Type & Description |
|---|---|
| 1 | for loop
This loop performs a set of statements for each item in a set of records. |
| 2 | SOQL for loop

| 3 | Java-like for loop
