uj5u.com熱心網友回復：
要學會貼代碼，問題是什么？
public static void main(String[] args) {
String format = "insert into table_a (grp_num, po_num) values('text','%s');\n";
File dataFile = new File("D:/test/data.txt");
File resultFile = new File("D:/test/result.sql");
try (BufferedReader reader = new BufferedReader(
new FileReader(dataFile));
BufferedWriter writer = new BufferedWriter(
new FileWriter(resultFile))) {
if (!resultFile.exists()) {
resultFile.createNewFile();
}
String tempStr;
while ((tempStr = reader.readLine()) != null) {
writer.write(String.format(format, tempStr));
}
writer.flush();
} catch (IOException e) {
e.printStackTrace();
}
}
