Consecutive as in 0543, 1234, 0009, 0034(a single digit counts as consecutive). I've written this part of code until now, the problem is I don't understand why is my line<br> boolean isTwoDigitConsecutive; isTwoDigitConsecutive = (w = 0) &amp;&amp; (x = 0) &amp;&amp; (y &lt;= 9) &amp;&amp; (y - z ==1); wrong. it says that i can't use &amp;&amp; with Int.</p> <p>I would like to have some clarifications on how to use boolean variable.</p> <p>Thank you in advance.</p> <p>*edit: Thank you for your help, I listened to your advice and changed my code accordingly. </p>
