I have modified the above program. And made esay the
process.


import java.util.ArrayList;

public class UniqueArrayListValues {

static ArrayList assignValues() {
ArrayList a1 = new ArrayList();
a1.add("A");
a1.add("B");
a1.add("C");
a1.add("27");
a1.add("A");
a1.add("B");
a1.add("C");
a1.add("27");
a1.add("A");
a1.add("B");
a1.add("C");
a1.add("27");
return a1;
}

static ArrayList applyUniqueKey(ArrayList a1) {
ArrayList a2 = new ArrayList();
for (int i = 0; i < a1.size(); i++) {
if (!a2.contains(a1.get(i))) {
a2.add(a1.get(i));
}
}
return a2;
}

public static void main(String args[]) {
ArrayList beforeUniqueKey = assignValues();
System.out.println("Before applying Unique
Key:" + beforeUniqueKey);
ArrayList afterUniqueKey = applyUniqueKey
(beforeUniqueKey);
System.out.println("Afrer applying Unique
Key:" + afterUniqueKey);
}

}
