Insert all elements of other Collection to Specified Index of Java Vector Example
This Java Example shows how to insert all elements of other Collection object
at specified index of Java Vector object using addAll method.

public static void main(String[] args) {
//create Vector object
Vector v = new Vector();
//Add elements to Vector
v.add("1");
v.add("2");
v.add("3");
//create a new ArrayList object
ArrayList arrayList = new ArrayList();
arrayList.add("4");
arrayList.add("5");
/*
To insert all elements of another Collection to sepcified index of Vector use
boolean addAll(int index, Collection c) method.
It returns true if the Vector was changed by the method call.
*/
//insert all elements of ArrayList to Vector at index 1
v.addAll(1,arrayList);
//display elements of Vector
System.out.println("After inserting all elements of ArrayList at index 1,
Vector contains..");
for(int i=0; i<v.size(); i++)
System.out.println(v.get(i));
}
}
/*
Output would be
After inserting all elements of ArrayList at index 1, Vector contains..
1
4
5
2
