Sample Solution:

Java Code:

// Importing necessary Java utilities.
import java.util.*;

// Define a class named Main.
class Main {
    
    // Define a method to check if a given string contains all the letters of another string.
    static void checkExistance(String str1, String str_to_search) {
        int chk = 0; // Variable to check existence.
        char chhr = ' '; // Character variable.
        int[] a = new int[Character.MAX_VALUE + 1]; // Array to store character counts.

        // Loop through each character of the first string and count occurrences.
        for (int i = 0; i < str1.length(); i++) {
            chhr = str1.charAt(i);
            ++a[chhr];
        }
        
        // Loop through each character of the string to search.
        for (int i = 0; i < str_to_search.length(); i++) {
            chhr = str_to_search.charAt(i);
            if (a[chhr] >= 1)
                chk = 1; // Set check flag if character exists in the first string.
        }
        
        // If check flag is set, print the first string.
        if (chk == 1)
            System.out.println(str1);
    }

    // Main method to execute the program.
    public static void main(String[] args) {
        // Create a list of strings.
        List < String > list = new ArrayList < String > ();
        list.add("rabbit");
        list.add("bribe");
        list.add("dog");

        // Print the given strings.
        System.out.print("The given strings are: ");
        for (int i = 0; i < list.size(); i++) {
            System.out.print(list.get(i) + "   ");
        }
        
        // Print the given word.
        System.out.println("\nThe given word is: bib ");
        System.out.println("\nThe strings containing all the letters of the given word are: ");
        
        // Check each string in the list for the existence of letters from the given word.
        for (int j = 0; j < list.size(); j++) {
            checkExistance(list.get(j), "bib");
        }
    }
}

Sample Output:

The given strings are: rabbit   bribe   dog   
The given word is: bib 

The strings containing all the letters of the given word are: 
rabbit
bribe
