try this 

 

 

you were not declaring the variable.

 

public class ListPrimitiveDataype
{
Public List<String> fstName{get;set;}
public ListPrimitiveDataype()
{
fstName= New List<String>();
fstName.add('praveen');
fstName.add('anil');
fstName.add('karthik');
}
}

try this

 

you are displaying the list<string> so you do not need any dot notation

 

Vf Page :

<apex:page controller="ListPrimitiveDataype">
<apex:form >
<apex:pageBlock >
<apex:pageblockTable value="{!fstName}" var="f">
<apex:column value="{!f}"/>
</apex:pageblockTable>

<apex:pageblockTable value="{!lstName}" var="f">
<apex:column value="{!f}"/>
</apex:pageblockTable>
</apex:pageBlock>
</apex:form>
</apex:page>

 

Apex Class:

public class ListPrimitiveDataype
{
public List<String> fstName{get;set;}
public List<String> lstName{get;set;}

public ListPrimitiveDataype()
{
fstName= New List<String>();
lstName= New List<String>();

fstName.add('fstName element1');
fstName.add('fstName element2');
fstName.add('fstName element3');

lstName.add('lstName element1');
lstName.add('lstName element2');
lstName.add('lstName element3');
}
}

Hi,

 

Please try the below code and let me know if it works.

 

public class ListPrimitiveDataype
{
Public List<String> () 
public ListPrimitiveDataype()
{
	fstName= New List<String>();
	fstName.add('praveen');
	fstName.add('anil');
	fstName.add('karthik');
}
}
 
<apex:page controller="ListPrimitiveDataype">
<apex:form >
<apex:pageBlock>
<apex:pageblockTable value="{!fstName}" var="f">
<apex:column value="{!f}"/>
</apex:pageblockTable>
</apex:pageBlock>
