In this example we will show how to insert all elements of other Collection object to specified index of java Vector object with addAll method.
Source Code
package com.beginner.examples;
import java.util.ArrayList;
import java.util.Vector;
public class InsertAllElementsOfOtherCollectionToVector {
public static void main(String[] args) {
//create Vector.
Vector vector = new Vector();
vector.add("A");
vector.add("B");
vector.add("C");
vector vector.add("D");
//create a new ArrayList
ArrayList arrayList = new ArrayList();
arrayList.add("1");
arrayList.add("2");
/*
* To insert all elements of another Collection to sepcified index of Vector use addAll method.
*/
vector.addAll(4,arrayList);
System.out.println("After inserting , Vector contains..");
for(int i=0; i<vector.size(); i++) {
System.out.println(vector.get(i));
}
}
}
Output:
After inserting , Vector contains..
