1,JDK7前的处理方式:
public class Text01 {
public static void main(String[] args) {
FileReader fileReader = null;
try {
fileReader = new FileReader("G:\\xxx");
} catch (FileNotFoundException e) {
e.printStackTrace();
}finally {
if (fileReader != null) {
try {
fileReader.close();
} catch (IOException e) {
e.printStackTrace();
}
}
}
}
}
2,JDK7后的处理方式:(推荐)
public class Text01 {
public static void main(String[] args) {
try (FileWriter fw = new FileWriter("G:\\xxx")) {
fw.write("sss");
} catch (IOException e) {
e.printStackTrace();
}
}
}
