Given a value N, the task is to create a List having this value N in a single line in Java using Collection Framework only. Examples:
Input: N = 5
Output: [5]

Input: N = GeeksForGeeks
Output: [GeeksForGeeks]
Approach: Below is the implementation of the above approach: Java
// Java program to initialize a list in a single
// line with a specified value
// using Collection Framework only

import java.io.*;
import java.util.*;
import java.util.stream.*;

class GFG {

    // Function to create a List
    // with the specified value
    public static <T> List<T> createList(T N)
    {

        // Currently only one value is taken
        int size = 1;

        // Generate a Collection with a single value N
        List<T> list = Collections.nCopies(size, N);

        return list;
    }

    // Driver code
    public static void main(String[] args)
    {

        int N = 1024;
        System.out.println("List with element "
                           + N + ": "
                           + createList(N));

        String str = "GeeksForGeeks";
        System.out.println("List with element "
                           + str + ": "
                           + createList(str));
    }
}
Output:
List with element 1024: [1024]
List with element GeeksForGeeks: [GeeksForGeeks]
