We are developing a Simulator with Students with Java and Swing. The Problem we have is that after a Button Click in the Simulator.java the variable for private static boolean startButton change too true. After this the "if" should start doing their job, but that is not the case.
I have this Code Block in my Brain.java:
public class Brain
{
// ==========================================================
/*
* This is the Part of Port A
*/
// Tris for Port A | ARRAY VALUE 0
private static boolean[] port_A_Tris_Checkboxes = new boolean[8];
// PINs | ARRAY VALUE 1
private static boolean[] port_A_Pins_Checkboxes = new boolean[5];
/*
* This is the Part of Port B
*/
// Tris for Port B | ARRAY VALUE 2
private static boolean[] port_B_Tris_Checkboxes = new boolean[8];
// PINs | ARRAY VALUE 3
private static boolean[] port_B_Pins_Checkboxes = new boolean[8];
// ==========================================================
/*
* This is the Part of the Watchdog
*/
private static boolean watchdogCheckbox;
// ==========================================================
/*
* This is the Part of the Reset Button
*/
private static boolean resetButton;
// ==========================================================
/*
* This is the Part of the Einzelschritt Button
*/
private static boolean einzelschrittButton;
// ==========================================================
/*
* This is the Part of the Start Button
*/
private static boolean startButton = false;
// ==========================================================
/*
* This is the Part of the Stop Button
*/
private static boolean stopButton = false;
// ==========================================================
public static void main(String[] args)
{
// startet das GUI
Simulator.main(args);
while (true) {
if ((startButton == true) && (stopButton == false)) {
// Do one step of the program
Steuerwerk.runCommand(Decoder.decode(Simulator.getProgramMemory()
.getProgramMemory()[ProgramCounter.getProgramCounter()]),
Simulator.getProgramMemory().getProgramMemory()[ProgramCounter
.getProgramCounter()]);
System.out.println(W_Register.getArgument());
} else if (getStart() && getStop()) {
/*
* If program has already started and the stop button was pressed,
* stop the program
*/
setStart(false);
setStop(false);
} else if (getStop()) {
// No reason to save stopping of program if it didn't even start yet
setStop(false);
} else if (getEinzelschritt()) {
// Do one step of the program
Steuerwerk.runCommand(Decoder.decode(Simulator.getProgramMemory()
.getProgramMemory()[ProgramCounter.getProgramCounter()]),
Simulator.getProgramMemory().getProgramMemory()[ProgramCounter
.getProgramCounter()]);
System.out.println(W_Register.getArgument());
setEinzelschritt(false);
}
}
}
// ==========================================================

public static void setChechboxesForTrisOrPinBoolean(int index,
int whichArray)
{
switch (whichArray) {
case 0: {

break;
}
case 1: {
port_A_Pins_Checkboxes[index] = !port_A_Pins_Checkboxes[index];

}
case 2: {

throw new IllegalArgumentException("Unexpected value: " + whichArray);

}
}
/*

public static boolean getStop()
{
return stopButton;
}
// ==========================================================
}
the other Part is my Simulator:
JButton btnStart = new JButton("START");
btnStart.addActionListener(new ActionListener() {
@Override
public void actionPerformed(ActionEvent e)
{
// TODO Auto-generated method stub
System.out.println("Pressed");
Brain.setStart(true);
}
});
The funny thing is that only if we add a System.out.println() or we Debug... it starts the if.
