Please update your code like below 
public class OpportunityExample 
{
	public date closedate{set;get;}
	public string stagename{set;get;}
	public decimal amount{set;get;}
	public string name{set;get;}
	public opportunity opp{set;get;}
	
	public OpportunityExample()
	{
		opp=new opportunity();
		opp.amount=amount;
		opp.name=name;
		opp.closedate=date.newinstance(2016,10,16);
		opp.stagename='closedwon';
	}
	public pagereference xample()
	{
		insert opp;
		pagereference pr = new pagereference('/'+opp.id);
		return pr;
	}
}
Let us know if this will help you

Your constructor should be like below

    public OpportunityExample()
    {
        opp=new opportunity();
        opp.amount=amount;
        opp.name=name;
        opp.closedate=date.newinstance(2016,10,16);
        opp.stagename='closedwon';
    }

opp=new opportunity();
//opp.amount=amount;
