java: How to write a generic type list [Note]

java: The merit of generic type is that the type is specified. It also shortens the code.


package demojava.demo14;

import java.util.ArrayList;
import java.util.List;

public class Demo14 {
	public static void main(String[] args) {

		for (int i = 0 ;i < C.length; i++){
		for (String val : L) {
