  1. POTimer in Java - few problems with mins/hours decrement
    text
    copied!<p>I am developing a Java countdown timer. I am totally new to Java though have done some C++ before so it's not all totally new. I am having problems with this - can anyone easily see what I have done wrong in the logic?</p> <p>What is happening:</p> <p>On run, if you enter in for example 23 in hours leave mins blank and put in 5 secs - the 5 secs should count to 0 - the mins should go to 59 and the hours to 22. However once the 5 secs elapses all digits go to zero.</p> <p>If on the input box I enter though 23 hours 1 in minutes and 5 in secs - when the 5 has elapsed it changes to 22 hours 59 mins 59 secs so I know its nearly there (just hoping I may have missed something silly.</p> <p>Finally the last problem with the logic - if I for example enter 30 mins 5 secs when the 5 have elapsed the mins go to 29 the secs go to 59 and continue counting down but the hours go to -1. Code below - sorry for long post but wanted to paint the scenarios - Thanks - Colly</p> <pre><code>Integer sec = new Integer (seconds.getText ()); Integer min = new Integer (minutes.getText ()); Integer hr = new Integer (hours.getText ()); int temp1 = sec.intValue (); int temp2 = min.intValue (); int temp3 = hr.intValue(); temp1--; if (temp1 == -1 ) { temp1 = 59; temp2--; if (temp2 == 0 &amp;&amp; temp3 != 0) { temp2 = 59; } temp3--; } hr = new Integer (temp3); sec = new Integer (temp1); min = new Integer (temp2); hours.setText (hr.toString ()); minutes.setText (min.toString ()); seconds.setText (sec.toString ()); if (seconds.getText ().length () == 1) seconds.setText ("0" + seconds.getText ()); </code></pre>
