Generic Classes
as functions classes can also be generic which accepts data types of any type variables. The syntax to define a generic class as :
class Gen<T> {
T ob; // declare an object of type T
// Pass the constructor a reference to
// an object of type T.
Gen(T o) {
ob = o;
}
// Return ob.
T getob() {
return ob;
}
}
public class GenericClasses {
public static void main(String args[]) {
Gen<Integer> iOb; // creating generic class object 1
iOb = new Gen<Integer>(88); // assigning integer type
int v = iOb.getob();
System.out.println("value: " + v);
System.out.println();
// creating generic class object 2 with string type
Gen<String> strOb = new Gen<String>("Generics Test");
String str = strOb.getob();
System.out.println("value: " + str);
}
}
