Question

Sample Input 1:

Enter the first letter:R
Enter the second letter:A
Enter the third letter:I
Enter the fourth letter:N
Enter the fifth letter:B
Enter the sixth letter:O
Enter the seventh letter:W

Sample Output 1:

RAINBOW

Sample Input 2:

Enter the first letter:R
Enter the second letter:E
Enter the third letter:I
Enter the fourth letter:N
Enter the fifth letter:B
Enter the sixth letter:O
Enter the seventh letter:W

Sample Output 2:

The spelling is wrong

Code:

public class spellcheck {
    public static void main(String[] args) {
        // TODO Auto-generated method stub
        Scanner scan = new Scanner(System.in);
        String str1;
        String str2 = "rainbow";
        int i = 0;
        String a[] = new String[7];
        System.out.print("Enter the first letter:");
        a[0] = scan.nextLine();
        System.out.print("Enter the first letter:");
        a[1] = scan.nextLine();
        System.out.print("Enter the first letter:");
        a[2] = scan.nextLine();
        System.out.print("Enter the first letter:");
        a[3] = scan.nextLine();
        System.out.print("Enter the first letter:");
        a[4] = scan.nextLine();
        System.out.print("Enter the first letter:");
        a[5] = scan.nextLine();
        System.out.print("Enter the first letter:");
        a[6] = scan.nextLine();
    }
}

What should be the next step?

Answer 1

String tmp = "";

for(int j = 0; j < a.length; j ++)
tmp += a[j];

System.out.println(tmp);

Output -

Enter the first letter:r
Enter the first letter:a
Enter the first letter:i
Enter the first letter:n
Enter the first letter:b
Enter the first letter:o
Enter the first letter:w
rainbow

To compare you can utilize the built in String function .equals -> tmp.equals("Otherstring")
