I am working on creating some Hashmaps in different ways. I am stuck at one place now. I assigned some values to an object and pass that object as value to Hashmap with the key as student. And not knowing how to retrieve those values.
Here is the code I wrote:
StudentHashMap stud=new StudentHashMap();//creating class object stud.firstName="Santhosh";//Assigning values to object stud.lastName="Nellutla"; stud.rollNumber=1; HashMap studentMap=new HashMap();// creating HashMap object studentMap.put("Student", stud); stud.studentDetails(studentMap);
