Question

I need this code to be written so that it can be tested please


public void decrementSeconds()
{
sec--;
if (sec <0)
{
sec = 59;
decrementMinutes(); //increment minutes
}
}
public void decrementHours()
{
hr--;
if (hr <0)
hr = 23;
}
public void decrementMinutes()
{
min--;
if (min <0)
{
min = 59;
decrementHours(); //decrement hours
}
}

 Or Maybe this will help I'm not sure
