How to check if a string starts with a substring from a list of substrings in Java

Answer 1

import java.util.List;

public class StartsWithAnyExample {
    // Function to check if the string starts with any substring from the list
    public static boolean startsWithAny(String string, List<String> substrings) {
        for (String substring : substrings) {
            // Use the startsWith method to check if the string starts with the substring
            if (string.startsWith(substring)) {
                return true;
            }
        }
        return false; // Return false if no substring matches
    }

    public static void main(String[] args) {
        String string = "abcdefg";

        // List of substrings
        List<String> substrings = List.of("xy", "poq", "mnop", "abc", "rsuvw");

        // Check if the string starts with any substring from the list
        if (startsWithAny(string, substrings)) {
            System.out.println("The string starts with a substring from the list.");
        } else {
            System.out.println("The string does not start with any substring from the list.");
        }
    }
}
