title: Trouble with loop and storing data in variables
body: <p>The program I am trying to finish needs to read in three numbers from the user and then store them in the variables <code>num1</code>, <code>num2</code> and <code>num3</code> so that they can be used in steps 2 and 3.  The problem I am having is that when the program loops through after the user inputs their numbers and tries to move on to step 2 or 3, it says must complete step 1 first.
  <br/>This is my code as of right now:</p>
  
  <pre><code>    static Scanner console = new Scanner(System.in);
  
      public static void main(String[] args) {
          // TODO Auto-generated method stub
  
          int num1;
          int num2;
          int num3;
          int input;
  
          do {
              boolean opt1Done = false;
              System.out.println("Select your next step");
              System.out.println("1: Enter three numbers between 1 and 100.");
              System.out.println("2: Order your number in ascending order");
              System.out.println("3: Determine if the three inputs form a triangle");
              System.out.println("4: Exit");
  
              int answer = console.nextInt();
              num1 = console.nextInt();
              num2 = console.nextInt();
              num3 = console.nextInt();
              input = console.nextInt();
  
              if (answer == 1) {
                  //do whatever for option 1
                  System.out.println("Enter a value for num1 between 1 and 100.");
                  System.out.println("Enter a value for num2 between 1 and 100.");
                  System.out.println("Enter a value for num3 between 1 and 100.");
  
                  opt1Done = true;
              } else if (answer == 2) {
                  if (opt1Done) {
                      //...... do whatever to order the numbers
                      int[] arraynum;
                      arraynum = new int[3];
  
                      arraynum[0] = num1;
                      arraynum[1] = num2;
                      arraynum[2] = num3;
  
                      Arrays.sort(arraynum);
  
                      int i;
  
                      for (i = 0; i &lt; arraynum.length; i++) {
                          System.out.println("num:" + arraynum[i]);
                      }
  
                  } else {
                      System.out.println("you must complete Step 1 before Step 2");
                  }
              } else if (answer == 3) {
                  if (opt1Done) {
                      //... do whatever to determine if triangle or not
                      if (num1 + num2 &gt; num3 &amp;&amp; num1 + num3 &gt; num2 &amp;&amp; num2 + num3 &gt; num1) {
                          System.out.print("TRIANGLE");
                      } else {
                          System.out.print("NO TRIANGLE");
                      }
                  } else {
                      System.out.println("you must complete Step 1 before Step 3");
                  }
                  if (answer == 4) {
                      System.exit(0);
  
                  }
              }
          } while (input != 4);
      }
  }

  <p>Do I need to add another loop or change the one already have?</p>
