title: If Statement not working
body: <p>I am new to programming and would appreciate some help. The slightest bit of insight would be highly appreciated. 
  I have an issue with the following code. The program emulates a calculator but currently my main focus is on if and else if statements. <strong>The issue is that no matter what the user selects, the program will always add the two numbers i.e. 'number1' and 'number2' in the code</strong></p>
  
  <pre><code>import java.util.*;
  public class Input
  {
      private Scanner input;
  
      public Input()
      { 
          input = new Scanner(System.in);
  
      }
  
      public void calculation()
      {
          double number1, number2, answer;
          String A, B, C, D, E;
          String option;
          A = "A"; B = "B"; C = "C"; D = "D"; E = "E"; //initialising the strings 
  
          System.out.println("add - option A \t (if your option is A, insert 'A')");
          System.out.println("multiply - option B");
          System.out.println("subtract - option C");
          System.out.println("divide - option D");
          System.out.println("power - option E (1st number - 'X' &amp; 2nd number - 'n' following X^n)");
          System.out.println("Remember Java is case sensitive, therefore, inserting 'a' as 'A' won't work");
          System.out.println();
          System.out.println("Insert your first number: ");
          number1 = input.nextDouble();
          System.out.println("Insert your second number: ");
          number2 = input.nextDouble();
          System.out.println("Choosing option: ");
          option = input.next();
  
          if(A == A)
          {
              answer = number1 + number2;
              System.out.println("Your answer is: " + answer);

          {
              answer = number1 - number2;
              System.out.println("Your answer is: " + answer);
  
          }else if(D == D)
          {
              answer = number1 / number2;
              System.out.println("Your answer is: " + answer);

          {
