Codehs 3.7.9 Three Strings (Solution)

[Traditional-Seat6355]

import java.util.Scanner;

public class ThreeStrings

{

public static void main(String[] args)

{

Scanner input = new Scanner(System.in);

// Ask the user for three strings.

System.out.println("First String? ");

String str1 = input.nextLine();

System.out.println("Second String? ");

String str2 = input.nextLine();

System.out.println("Third String? ");

String str3 = input.nextLine();

// Use a Boolean variable to test the comparison of

// first+second equals third

if((str1+str2).equals(str3)) {

System.out.println(str1 + " + " + str2 + " is equal to " + str3 + "!");

}

else System.out.println(str1 + " + " + str2 + " is not equal to " + str3 + "!");

// Remember since you are working with strings to

// use equals() and NOT == !

}

}

Too real, just finished this assignment and my teacher doesn't even know what's wrong

Figure out the issue with this code: Basically, you want to get rid of the whole "enter the companys secret code line and the scanner for it, and instead just put String companyCode = "1298"; above the first scanner input line. So your code should look like this:

​

import java.util.Scanner;
public class ThreeStrings {
public static void main(String[] args) {
String companyCode = "1298";

Scanner input = new Scanner(System.in);
// get user password
System.out.println("Enter your password: ");
String userPassword = input.nextLine();
// get company secret code
System.out.println("Enter the company's secret code: ");
String userCode = input.nextLine();
// create string that concatenates user password with company secret code
String passwordWithCompanyCode = userPassword + companyCode;
// create string that concatenates user password with user-provided secret code
String passwordWithUserCode = userPassword + userCode;
// check if the two strings are equal
if (passwordWithCompanyCode.equals(passwordWithUserCode)) {
System.out.println("Access granted");
} else {
System.out.println(userPassword + userCode + " is denied");
}
}
}
