Else if part is not getting executed

[Alvaroo Hernandez]

import java.util.Scanner;

public class ProgramExam3 {
	public static void main(String[] args) {

		int firstInt;
		double firstDouble;
		int secondInt;
		double secondDouble;
		int thirdInt;
		double thirdDouble;
		String firstWord;
		String secondWord;
		String thirdWord;

		Scanner input = new Scanner(System.in);
		System.out.print("Enter in order: a word, an integer, a double,"
				+ " an integer, a double, an integer, a double, and two words:");
		firstWord = input.next();
		firstInt = input.nextInt();
		firstDouble = input.nextDouble();
		secondInt = input.nextInt();
		secondDouble = input.nextDouble();
		thirdInt = input.nextInt();
		thirdDouble = input.nextDouble();
		secondWord = input.next();
		thirdWord = input.next();

		int str1 = firstWord.length();

		if (firstInt + thirdInt > 10 && str1 > 10) 
		{
			System.out.println(thirdDouble + firstWord + secondWord
					+ thirdWord);
		}
		else if (secondDouble < 8.8 || firstWord == secondWord)
		{
			System.out.printf("%f + %f, %f + %f + %f, %d\n %d", secondInt,
					thirdInt,firstInt, secondInt, firstDouble, secondWord,
					thirdWord);
		}
		else
		{
		
			System.out.println("Farewell " + thirdWord);
		}
		input.close();
	}
	
}

the input is Tyrannosaurus, 4, 2.2, 3, 9.9, 5, 1.1, Tyrannosaurus, Rex

Can anybody explain to me why this doesn't execute the else if part because its supposed to or are my curly braces in the wrong places? when i run it, it outputs the farewell part. any tips??

Don't compare String instances with the == operator. You must use firstWord.equals(secondWord).
The == operator will determine whether the String variables refer to the same String instance, not whether the contents of two instances are the same.
