Java Program to append all elements of other Collection to ArrayList
Let us first create an ArrayList −
ArrayList<String>arr = new ArrayList<String>();
arr.add("50");
arr.add("100");
arr.add("150");
arr.add("200");
arr.add("250");
arr.add("300");Now, let’s say we have another Collection as Vector −
Vector<String>vector = new Vector<String>();
vector.add("500");
vector.add("700");
vector.add("800");
vector.add("1000");
Append all the elements from the Vector to ArrayList:
arr.addAll(vector);Example
import java.util.ArrayList;
import java.util.Vector;
public class Demo {
public static void main(String[] args) {
ArrayList<String>arr = new ArrayList<String>();
arr.add("50");
arr.add("100");
arr.add("150");
arr.add("200");
arr.add("250");
arr.add("300");
Vector<String>vector = new Vector<String>();
vector.add("500");
vector.add("700");
vector.add("800");
vector.add("1000");
// append
arr.addAll(vector);
System.out.println("Result after append...");
for (String str: arr)
System.out.println(str);
}
}Output
Result after append... 50 100 150 200 250 300 500 700 800 1000
