you need read content jsonobject. can add code snippet

jsonarray jsonarray = yourjsonobject.getjsonarray("contacts"); //here yourjsonobject object has array in question. for(int = 0; i<jsonarray.length(); i++) {  jsonobject jobject = jsonarray.getjsonobject(i);  string name = jobject.getstring("name");  if(name.equals("michael jordan")) {  system.out.println("name exists");  } }
