How do you call 2 or more objects in c plus plus?
It's not clear what you mean by "call 2 or more objects". Object's aren't "called", they are instantiated. Once instantiated you may "call" (invoke) the member methods associated with those objects, or invoke functions that operate upon those objects. To invoke the same member method on 2 or more objects, simply place those objects in a vector (by reference), then iterate over the vector: void f (std::vector<my_object*> objects) { for (auto foo : objects) foo->bar(); // invoke the bar method for each foo object in objects }
Can vector store string values in java programming?
A Vector can store any objects, so yes.
How do you implement vector?
import java.util.Vector; public class VectorTest { /** * @param args */ public static void main(String[] args) { //instantiating a vector Vector vct = new Vector(); //Add objects to a vector vct.add("One"); //getting values from the vector String val = (String) vct.get(0); //vector size System.out.println("Vector size is: " + vct.size()); //removing elements from a vector vct.remove(0); } }
How many number of objects we can store in an ArrayList. Is there any limit?
No. there is actually no such limit in any of the collections in java. The arraylist and vector are the most commonly used collections and they take thousands of objects. I have personally used them with atleast a 100,000 thousand objects.
What is an arrey and how many types of arrey in details?
An array is a data type that describes a collection of ordered variables and types of arrays include vector arrays and matrix arrays.
