public class TestReadTxt {
public static void readTxtFile(String filePath){
try {
String encoding="GBK";
File file=new File(filePath);
if(file.isFile() && file.exists()){ //判断文件是否存在
InputStreamReader read = new InputStreamReader(
new FileInputStream(file),encoding);//考虑到编码格式
BufferedReader bufferedReader = new BufferedReader(read);
String lineTxt = null;
while((lineTxt = bufferedReader.readLine()) != null){
System.out.println(lineTxt);
}
read.close();
}else{
System.out.println("找不到指定的文件");
