16. How do you pass the parameters from on apex class to another to another ?
Answer: You can simply pass the parameters through the URL.

say you are redirecting from one VF page to another

string value = ‘your param value’;

string url;

url = ‘/apex/VF_Page_Name?param1=’ + value;

PageReference pageRef = new PageReference(url);

pageRef.setRedirect(true);

return pageRef;

Then in the controller of the VF page, you just can get the param like this

String param_value = system.CurrentPageReference.GetParameters().get(‘param1’);
