asd@as.asd PageReference
hello,
i am bit confusing using these three methods. it's look like same or is there any deffernce among these methods.
plz help me
public PageReference next() {
PageReference pp=new PageReference('https://c.ap1.visual.force.com/apex/demoControllerPage1);
return pp;
}
public PageReference next() {
return Page.demoControllerPage1;
}
public PageReference next() {
PageReference acctPage = new ApexPages.StandardController(account).view();
acctPage.setRedirect(true);
return acctPage;
}
Page reference is returned in all three methods. But there are some differences in the way of the set the page to page reference.
1 st method : You have set the page by using actual URL. This is not recommened.
2nd method : You have use the just page name for set the page for pageReference.
3rd method : You have use standard controller and the view page layout of account object. Every object has standard controller with its methods and few page layouts. In 3rd method, you have used the view method of account object's standard controller.

return acc;
}
list<Account> acc;
public PageReference next() {
PageReference pp=new PageReference('https://c.ap1.visual.force.com/apex/demoControllerPage1);
return pp;
// return Page.demoControllerPage1;
}
public list<Account> getData() {
acc=[select name from Account];
