[SalesForce] How to add string values using apex

I have two string values using numbers. How to add(not concatenate) the two string values. Could you please help me.

my code:

string num='2016';
system.debug('first:'+num);
Output: 2016

string num1='2016'+'1';
system.debug('second:'+num1);
Output: 20161

But I need 2017.Is it possible or not this way?

Best Answer

Integer num = Integer.valueOf('2006');
Integer num2 = Integer.valueOf('1');

Integer result = num + num2;
System.debug(result);

Update as per comment, to transform it to a String:

String str = String.valueOf(result);
System.debug(str);

[SalesForce] How to insert object records using list of string

You would have to reinitialise the "l" instance variable inside your loop everytime you insert a new lead record in the list, as the elements are stored by reference.

while(i<3){
l.firstname = first.get(i);
l.lastname = last.get(i);
l.company = com.get(i);
i++;
lead.add(l);
l = new Lead();
system.debug('lead:'+lead);
}

Just define a field in your controller

private List<SelectOption> someOptions = new List<SelectOption>{
    new SelectOption('One','One'),
    new SelectOption('Two','Two'),
    new SelectOption('Three','Three')
};

on particular events/actions - manipulate the items in list

on visualforce page use this field for select options

<apex:selectList id="someSelection" value="{!someValue}" multiselect="true" >
  <apex:selectOptions value="{!someOptions}"/>
</apex:selectList>
