向量到JTable的向量

Question

我將一些數據保存在向量的向量中

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

而且我需要在JTable中顯示該數據，但是問題是當我使用Iterator時：

Iterator it=dataList.iterator();

不要具有next（）或hasNext（）方法。 我嘗試轉換Iterator，但id卻無濟於事...我嘗試了2個Forech循環，但又遇到問題

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

但是我又遇到了問題，因為方法get（）需要int參數...請給mi一些有用的解決方案親切的問候

Answer 1

應該：

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

Answer 2

更新！ 我必須通過串行端口從Arduino do Java發送結果並將其顯示在表中。 我在那兒張貼了我在Arduino和Java中的Java程序和代碼中得到的結果圖像

我的Arduino代碼：

 #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; 
}
