Answer:

Here is the corrected program:

import java.util.Scanner; //to accept input from user

public class 02_14_Activity_one { //class name

public static void main(String[] args) { //start of main method

Scanner scan = new Scanner(System.in); //creates Scanner class object

System.out.println("Enter first string"); //prompts user to enter first string

String s1 = scan.nextLine(); //reads input string from user

System.out.println("Enter second string"); //prompts user to enter second string

String s2 = scan.nextLine(); //reads second input string from user

System.out.println("Enter number of letters from each word"); //enter n

int n = scan.nextInt(); //reads value of integer n from user

System.out.println(s1.substring(0,n) + s2.substring(s2.length() - n ));

} } //uses substring method to print a string made up of the first n letters of s1 and the last n letters of s2.

Explanation:

The errors were:

Scanner scan = Scanner(System.in);

Here new keyword is missing to create object scan of Scanner class.

Corrected statement:

Scanner scan = new Scanner(System.in);

String s1 = nextLine();

Here object scan is missing to call nextLine() method of class Scanner

Corrected statement:

String s1 = scan.nextLine();

String s2 = Scanner.nextLine();

Here class is used instead of its object scan to access the method nextLine

Corrected statement:

String s2 = scan.nextLine();

String n = scan.nextLine();

Here n is of type String but n is a whole number so it should be of type int. Also the method nextInt will be used to scan and accept an integer value

Corrected statement:

int n = scan.nextInt();

System.out.println(s1.substring(1,n-1) + s2.substring(s1.length()-n));

This statement is also not correct

Corrected statement:

System.out.println(s1.substring(0,n) + s2.substring(s2.length() - n ));

This works as follows:

s1.substring(0,n) uses substring method to return a new string that is a substring of this s1. The substring begins at the 0th index of s1 and extends to the character at index n.

s2.substring(s2.length() - n ) uses substring method to return a new string that is a substring of this s2. The substring then uses length() method to get the length of s2 and subtracts integer n from it and thus returns the last n characters of s2.
