嵌套的if语句 - Apex中文手册

嵌套if-else

我们也可以有复杂条件的嵌套if-else语句，如下所示：

语法：

if boolean_expression_1 {
   /* Executes when the boolean expression 1 is true */
   if boolean_expression_2 {
      /* Executes when the boolean expression 2 is true */
   }
}

示例：

String pinCode = '12345';
String customerType = '12345';
if (pinCode == '12345') {
    System.debug('Condition met and Pin Code is'+pinCode);

    if(customerType = 'Premium') {
        System.debug('This is a Premium customer living in pinCode 12345);
    }
    else if(customerType = 'Normal') {
        System.debug('This is a Normal customer living in pinCode 12345);
    }
}
else {
    //this can go on as per the requirement
    System.debug('Pincode not found');
}
