public static void main(String[] args) {
//create a ArrayList object
ArrayList arrayList = new ArrayList();
//Add elements to ArrayList
arrayList.add("A");
arrayList.add("B");
arrayList.add("D");
/*
To replace all elements of Java ArrayList with specified element use,
static void fill(List list, Object element) method of Collections class.
*/
System.out.println("Before replacement, ArrayList contains : " + arrayList);
Collections.fill(arrayList,"REPLACED");
System.out.println("After replacement, ArrayList contains : " + arrayList);
}
}
/*
Output would be
Before replacement, ArrayList contains : [A, B, D]
