List<String> myList1 = new ArrayList<String>();
myList1.add("God");
myList1.add(".Net");
myList1.add("PHP");
myList1.add("Java");
List<String> myList2 = new ArrayList<String>();
myList2.add("C");
myList2.add("Java");
myList2.add("C++");
myList2.add(".Net");
List<String> commonList = new ArrayList<String>();
for (String list2Val : myList2) {
for (String list1Val : myList1) {
if (list2Val.equalsIgnoreCase(list1Val)) {
commonList.add(list2Val);
}
