import java.io.FileReader; import java.io.IOException; import java.util.ArrayList; public class aa { public static void main(String[] args) throws IOException{ FileReader fr = new FileReader("LBS.csv"); BufferedReader br = new BufferedReader(fr); String str = null; String Data[][]; ArrayList name = new ArrayList(); ArrayList number = new ArrayList(); ArrayList longitude = new ArrayList(); ArrayList latitude = new ArrayList(); //int num = 0; while((str = br.readLine())!= null){ String tempArray[] = str.split("\\,"); name.add(tempArray[0]); number.add(tempArray[1]); longitude.add(tempArray[2]); latitude.add(tempArray[3]); } Data = new String [name.size()][4]; for(int i = 0; i< name.size(); i++){ Data[i][0] = (String) name.get(i); Data[i][1] = (String) number.get(i); Data[i][2] = (String) longitude.get(i); Data[i][3] = (String) latitude.get(i); } for(int i = 0; i < Data.length; i++) { for(int j = 0; j < Data[0].length; j++) { for(int x = 0; x <= 300; x++) { for(int q = 0; q <= 300; q++) { //System.out.printf("x="+x+"q="+q+"\n"); System.out.println(x+" "+Data[x][1]+" "+q+" "+Data[q][1]); } } } } } } 執行程式，結果是 0 1_1 0 1_1 ~ 0 1_1 299 10_30 但是我想要的結果是 0 1_1 0 1_1 ~ 0 1_1 299 10_30 ~ 299 10_30 0 1_1 ~ 299 10_30 299 10_30 要怎麼修改？
