Hello friends, today we are going to discuss Most Common Salesforce Apex Operations. We all know there are many small-2 pieces of code in the apex that we need every time when we do code.

Key Highlights :
- Here we will put apex operations.
- These operations will help do code in apex easily.
Apex Operations:
1. Set Key Values in Map in For Loop
public class ApexCommanMapMethod {
public static void setKeyValueInMap(){
//store the same email with amount
Map<String, Decimal> mapOfCon = new Map<String, Decimal>();
for(Contact con : [SELECT Id, Email, Amount__c FROM Contact LIMIT 100]){
if(!mapOfCon.containsKey(con.Email)){
mapOfCon.put(con.Email, 0.00);
}
Decimal amount = mapOfCon.get(con.Email);
amount = amount + con.Amount__c;
mapOfCon.put(con.Email, amount);
}
System.debug('map debug==> '+ mapOfCon);
}
}
2. Convert comma-separated String to a List
String comaSeperateString = 'x, y, z';
List<String> listOfString = comaSeperateString.split(',');
System.debug(listOfString);
3. SOQL Query and get a MAP returned
Map<ID, Account> m = new Map<ID, Account>([SELECT Id, Name, Type FROM Account]);
4. Get Set of Id from Sobject List
List<Account> accountList = [SELECT Id, Name, Type FROM Account];
Set<Id> acountIds = (new Map<Id,SObject>(accountList)).keySet();
5. Get Map Keys and Values in Apex
Map<String, Integer> monthsMap = new Map<String, Integer>{'January' => 1,'February' => 2, 'March' => 3};
System.debug('mapKeys==>' + monthsMap.keys());
System.debug('mapValues==>' + monthsMap.values());
6. Generate a random string in Apex
public static String generateRandomString(Integer length) {
String chars = 'ABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789abcdefghijklmnopqrstuvwxyz';
String randomString = '';
while (randomString.length() < len) {
Integer idx = Math.mod(Math.abs(Crypto.getRandomInteger()), chars.length());
randomString += chars.substring(idx, idx+1);
}
return randomString ;
}
7. Get Day, Month and Year From Date Field Using Apex
Date dt = System.today(); //current date
Integer day = dt.Day(); //get day
Integer month = dt.Month(); //get month
Integer year = dt.Year(); //get year
8. Convert String to Date in Apex
Date parseDate = date.parse('04/08/2022');
System.debug('parseDate ==> ' + parseDate);
9. Convert String to DateTime in Apex
System.debug(DateTime.parse('11/08/2022, 10:21 AM'));
10. Check User has a Custom Permission in Salesforce Using Apex
Boolean hasCustomPermission = FeatureManagement.checkPermission('CUSTOM_PERMISSION_API');
11. Convert DateTime to Date in Apex
DateTime dt = System.now()
Date d = dt.date();
System.debug('Date==>' + d);
12. Set and Get Sobject fields dynamically
for(Contact con:conList) {
String fieldValue = (String) con.get(selectedField);
con.put(selectedField, 'test');
}
13. Get Week Number From Date in Apex
// Cast the Date variable into a DateTime
DateTime dtTime = (DateTime) yourDate;
String dayOfWeek = myDateTime.format('E');
System.debug('dayOfWeek==>' + dayOfWeek);
// dayOfWeek is Sun, Mon, Tue, etc.
14. Check If a text field is Empty in Apex
if(String.isBlank(Field)){
System.debug(Field + ' is Empty');
}
15. Round a Decimal Number to two decimal places
Decimal num1 = 1.254754;
Decimal roundNum = num1.setScale(2);
system.debug(roundNum);
