if-statments in java(need help)

i am trying to learn italian and i thougth that memorising the basic words would be a good idea. so i built a program that randomly chooses a word and asks what that word means in english. this is how the program looks:

package övningar;

import java.util.Random;

import java.util.Scanner;

public class italian {

    public static void main(String[] args) {
        String Ital[] = {"io","tu","lui","lei","noi","voi"}; //italian words
        String Eng[] = {"i","you","he","she","we","you all"}; // english words
        Scanner Input = new Scanner(System.in);// input scanner
        int num;// the variable that holds the random number 
        String answer;// the variable that holds the answer

        Random words = new Random(); //generator

        while(true) {
              num = words.nextInt(6); // generating

              System.out.println("what is ´" + Ital[num] + "´ in english? :"); //asking what the word means in english
              answer = Input.nextLine(); // input to question

              if(Eng[num] == answer){ //checking to see if the answer is correct
                  System.out.println("that's correct \n");
              }
              else
                  if( Eng[num] != answer) // checking to see if the answer is false
                      System.out.println("that's incorrect, ´" + Ital[num] + "´ = ´" + Eng[num] + "´ in english \n");
              else//exiting the program if no answer is received
                  System.exit(0);

        }
    }

}

butt every time i execute the program the allways says the its incorrect. i don't know what im doing wrong, please someone help me!
