Android accessing parent class values after starting an intent? -

i'm starting intent in activity class ttwifi.java follows

intent = new intent(this, socketclient.class);  startactivity(i); 

now how access variables of ttwifi.class socketclient.class?

i believe there way send values between them. new android, guess fundamental stuff :) appreciate if can me out in this...

through following code can share values activities

intent i=new intent(fitnessgraph.this,nami.class).putextra("<stringname>"," string value"); 

use above code in parent activity , using below line can retrieve value in child activity.write line in child activity

string s= getintent().getstringextra("<stringname>");
