This is the first time I have requested your help, I am doing this code as a task and I have not managed to get the accumulator "totaldia" to save the data that the "Shutdown" variable sends. I would appreciate it if you make me see where I fail. Thanks.

Each time the actionPerformed method is called, the totaldia variable is created and initialized to zero. If what you want is that every time that method is called it is updated all day long you must make a small trap, create a class dedicated only to contain the value of totaldia. Something like this:

public class Totaldia {
private double total;
public Totaldia(double total) {
    // TODO Auto-generated constructor stub
    this.total = total;
}
public double getTotal() {
    return total;
}
public void setTotal(double total) {
    this.total = total;
}

}

Then use a final instance of the Totaldia class instead of your double primitive variable.
