因此,我應該在UTF-16編碼的文件中插入信息,而不是一些操作(計數行,單詞等)。問題是,如果我選擇UTF-16編碼,則會引發異常,但UTF-8正常工作。以UTF-16編寫的文件無法打開,但UTF-8可以
import java.io.*;
import java.util.Scanner;
public final class Q4 {
public static void main(String[ ] args)throws FileNotFoundException{
final String ENCODING = "UTF-16";
final String FILE = " testcount";
PrintWriter out = null;
// Given code – do not modify(!) This will create the UTF-16 test file on your drive.
try {
out = new PrintWriter(FILE, ENCODING);
out.write("Test file for UTF-16\n" + "(contains surrogate pairs:\n" +
"Musical symbols in the range 1D100–1D1FF)\n\n");
out.write("F-clef (1D122): \uD834\uDD22\tCrotchet (1D15F): \uD834\uDD5F\n");
out.write("G-clef (1D120): \uD834\uDD20\tSemiquaver (1D161): \uD834\uDD61\n");
out.write("\n(? lines, ?? words, ??? chars but ??? code points)\n");
} catch (IOException e) { System.out.println("uh? cannot write to file!");
} finally { if (out != null) out.close();
}
// Your code – scan the test file and count lines, words, characters, and code points.
Scanner fin = new Scanner(new File(FILE));
String s = "";
//get the data in file
while (fin.hasNext()){
s = s + fin.next();
System.out.println(s);
}
fin.close();
//count words and lines
}
}
我唯一的猜測,一個遙不可及的一個,就是它必須是與該操作系統(Windows 8.1)不能夠保存UTF-16代碼,但聽起來像一個愚蠢的猜測。
而例外的是......? –
是的,它拋出了一個異常。你指的是什麼? –
我在問這是什麼例外。此刻,就好像你要去看醫生一樣,說「我有什麼不對勁」,但沒有再給出任何症狀。 (提示:改變'catch'塊打印出'e' ...) –
