Question

我在Vector of vector中保存了一些数据

Vector<Vector<String>> dataList= 
new Vector<Vector<String>>();

我需要在JTable中显示数据，但问题是当我使用Iterator时：

Iterator it=dataList.iterator();

没有next（）或hasNext（）方法。我试图施放Iterator但是id没有帮助...... 我尝试了2个前进循环，但我又遇到了问题

 for(Vector<String> v : dataList) {
for(String s: v) {
tableMod.addRow(v.get(s));
} 
}

但我又有问题，因为方法get（）需要int参数... 请给mi一些有用的解决方案亲切的问候

Answer 1

应该是：

for(Vector<String> v : dataList) {
    tableMod.addRow(v);
}

Answer 2

UPDATE！我必须通过串口从Arduino do Java发送结果并在表格中显示它们。我在那里发布了我在java程序中获得的结果图像以及Arduino和Java中的代码

我的Arduino代码：

In [13]: %timeit (x == 35).view(np.uint8)
20.1 ms ± 93.2 µs per loop (mean ± std. dev. of 7 runs, 10 loops each)

In [15]: %timeit np.isin(x, 35).view(np.uint8)
30.2 ms ± 1.16 ms per loop (mean ± std. dev. of 7 runs, 10 loops each)

我的Java代码：

 #define pinPWM 6
 #define analogPinIn A0 
 #define analogPinOut A1

const int r = 68;
const int R = 470;

int valAnalogPinIn; 
int valAnalogPinOut; 

int Udig[10]={120,135,150,165,180,195,210,225,240,255};
int voltageDigi,ii=0;
int noMeasuring=30;
float voltageIn;
float voltageOut;
float avrVoltageIn;
float avrVoltageOut;
float U;

void setup() {
 pinMode(pinPWM,OUTPUT);
 Serial.begin(9600);

}

void loop() {

int br=0;
float Uin, Uout, Ia;

 while(ii<=10-1){
 analogWrite(pinPWM,Udig[ii]);
 Serial.print(Udig[ii]);  
 Uin=measurUin();
 Uout=measurUout();
 U=Uin-Uout;
 Ia=U/r;
  Serial.print(",");
  Serial.print(Uin);
 Serial.print(",");
 Serial.print(Uout);
 Serial.println();


 ii=ii+1;
 delay(1);

  }    

}

float measurUin(){

 long sumVoltageIn=0;

 for(int i=1;i<=noMeasuring;i++){
valAnalogPinIn=analogRead(analogPinIn);
sumVoltageIn=sumVoltageIn+valAnalogPinIn; 
delay(1);

}
avrVoltageIn=sumVoltageIn/noMeasuring; 
avrVoltageIn=avrVoltageIn*(5.0/1024);

 return avrVoltageIn;
}
float measurUout(){

 long sumVoltageOut=0;

  for(int i=1;i<=noMeasuring;i++){
 valAnalogPinOut=analogRead(analogPinOut);
 sumVoltageOut=sumVoltageOut+valAnalogPinOut; 
  delay(1);

  }
  avrVoltageOut=sumVoltageOut/noMeasuring; 
  avrVoltageOut=avrVoltageOut*(5.0/1024);

  return avrVoltageOut; 
}
