import java.util.ArrayList;
 
 
 
 

public class ArrayPass {ArrayList<Integer> arraylist = new ArrayList<Integer>();
public ArrayList<Integer> MyArrayList(int [] a1)
{
for(Integer a : a1)
{arraylist.add(a);
System.out.println(a);}
return arraylist;
 

}

public static void main(String [] args)
{ArrayPass ap = new ArrayPass(); 
ArrayList<Integer> a = new ArrayList<Integer>();
int [] a1 = {1,2,3,4,5};
a = ap.MyArrayList(a1);
for(Integer b : a){
System.out.println(" after passing : "+ b);
}}
 
 

}
