Question

Using Java, Write a method , getFirstLine, that is passed a String  argument and that returns the first line. (Recall that lines are terminated with the "\n" character .) Assume that the argument contains at least one complete, newline-terminated line.

Answer 1

/*Program to Get the firstline*/

import java.util.Scanner;

/*NewLine Class*/
public class NewLine {

   public static void main(String[] args){
       Scanner s=new Scanner(System.in);
      
       String first=   "This is Chegg \n "+
               "and you are looking for first line result";
      
       System.out.println(getFirstLine(first));
   }

   /*Method to return the first string*/
   public static String getFirstLine(String input) {

       String lines[] = input.split("\n");

       String firstLine = lines[0];

       return firstLine;
   }

}

Result: ------

This is Chegg
