Let’s start with controller code.

public with sharing class retrieveStageValue {
    
    /**
      * Webkul Software.
      *
      * @category  Webkul
      * @author    Webkul

      */
    
    public list getoppst(){
        
        //Create a list of select option type
        list<selectoption> opt = new list<selectoption>();
        
        //FieldDescription=SObjectName.FieldName.getDescribe()
        schema.DescribeFieldResult fd = opportunity.stagename.getdescribe();
        
        //Get all picklist value in a list of scheme.picklistentry type
        list<scheme.picklistentry> pc = fd.getpicklistvalues();
        
        //Add each value in the list of selectoption
        for(schema.picklistentry f: pc){
        
            opt.add(new selectoption(f.getlabel(),f.getvalue()));
        
        }
    
        return opt;
    }
    
}

Now the visualforce page code:

<apex:page controller="retrieveStageValue">

    <!--
        /**

          * @license   https://store.webkul.com/license.html
          */
      -->
    <apex:form >
    
        <apex:sectionHeader title="Opportunity" subtitle="Status Picklist Value"/>
        
        <apex:pageblock >
        
            <apex:pageblocksection >
            
                <apex:pageblocksectionitem >
                
                    <apex:outputlabel value="Opportunity Stage"/>
                    <apex:selectlist size="1">
                    
                        <apex:selectoptions value="{!oppst}" />
                    
                    </apex:selectlist>
                
                </apex:pageblocksectionitem>
            
            </apex:pageblocksection>
        
        </apex:pageblock>
    
    </apex:form>

</apex:page>
