我想在我的代码下方显示类中textbox的字符串vpsfame，但我无法显示它。你能给我建议这个字符串在new8代码中的类中显示吗？串行类给我来自gps的字符串继续。它还在运行时通过 System.out.println 显示它，但不通过textboxofvpsfame类显示它

包vpspro；

public class Serial
{
public void com() throws UnsupportedCommOperationException, IOException, TooManyListenersException
{
int c=1;

String wantedPortName="COM6";

Enumeration portIdentifiers = CommPortIdentifier.getPortIdentifiers();

CommPortIdentifier portId = null;  
while(portIdentifiers.hasMoreElements())
{
    CommPortIdentifier pid = (CommPortIdentifier) portIdentifiers.nextElement();
    if(pid.getPortType() == CommPortIdentifier.PORT_SERIAL &&
       pid.getName().equals(wantedPortName)) 
    {
        portId = pid;
        break;
    }
}
if(portId == null)
{
    System.err.println("Could not find serial port " + wantedPortName);
    System.exit(1);
}
else
{
    System.out.println("system find gps reciever");
}
SerialPort port = null;
try {
    port = (SerialPort) portId.open(
        "RMC", 
        1);
    System.out.println("all are ok"); 
} catch(PortInUseException e) {
    System.err.println("Port already in use: " + e);
    System.exit(1);
}

port.setSerialPortParams(
    4800,
    SerialPort.DATABITS_8,
    SerialPort.STOPBITS_1,
    SerialPort.PARITY_NONE);



BufferedReader is = null;  


try {
  is = new BufferedReader(new InputStreamReader(port.getInputStream()));
  System.out.println("data is ok");
} catch (IOException e) {
  System.err.println("Can't open input stream: write-only");
  is = null;
}

String pt=null;
while(true)
{

String st = is.readLine();


        System.out.print("(" + c + ")");
        c++;
        new8 obj1 = new new8();

        obj1.decode(st);
        System.out.println(st);
        st = st.replace(st, "");


}

if (is != null) is.close();
/*if (os != null) os.close();*/
if (port != null) port.close();


}
}

此代码用于开始与串行类通信

我会认真建议您花点时间，并重构您的所有代码。忽略在类new8中，在方法中decode替换此代码：

new vpsfame().ac.setText(t[1].substring(1,2));
System.out.println("Lattitude:                                  "+t[3]);


System.out.println("Direction of Lattitude:                     "+t[4]);
new vpsfame().ab.setText(t[3].concat(t[4]));
System.out.println("Longitude:                                  "+t[5]);
System.out.println("Direction of Longitude:                     "+t[6]);
new vpsfame().bc.setText(t[5].concat(t[6]));
System.out.println("Speed over Ground:                          "+t[7]);
new vpsfame().cd.setText(t[7]);

有了这个：

//use one object, dont just create new frames
vpsfame myFrame = new vpsfame();

myFrame.ac.setText(t[1].substring(1,2));
System.out.println("Lattitude:                                  "+t[3]);
System.out.println("Direction of Lattitude:                     "+t[4]);

myFrame.ab.setText(t[3].concat(t[4]));
System.out.println("Longitude:                                  "+t[5]);
System.out.println("Direction of Longitude:                     "+t[6]);

myFrame.bc.setText(t[5].concat(t[6]));
System.out.println("Speed over Ground:                          "+t[7]);
myFrame.cd.setText(t[7]);

//Also set the frame to visible, so it can be displayed once you've done all this work.
myFrame.setVisible(true);

问题是：

  1. 首先，您正在创建多个 vpsframe 对象，而您应该只有一个。创建 5 个帧，每个帧都有 4 个空字段是没有意义的。创建一个对象并初始化它的所有字段，而不是使用 5 个不同的对象。
  2. 您没有跟踪您正在创建的对象，垃圾收集器只会摆脱它们，因此创建一个对象，将其分配给一个变量并使用它。
  3. 将 vpsfame 对象设置为可见，否则您将永远看不到它。

您的代码也需要重构，您应该使用 camelCase 命名约定，并且类应该始终以大写字母开头。
