Read Japanese Character using Scanner

问题

Possible duplicate: How can I read Chinese characters correctly using Scanner in Java?

My input file name may have japanese characters and I am trying to read the file name using Scanner.

Scanner sc = new Scanner(System.in,"utf-8");
System.out.println("Encoding is :" + Charset.defaultCharset());

System.out.println("Enter the path:");
inputFilePath = sc.nextLine();

and if my input is for eg - 漢字

When I print the file name my output is

Encoding is :UTF-8
Input File Path:漢字

I also tried,

byte[] jis = sc.nextLine().getBytes("Shift_JIS");
System.out.println(new String(jis));

and My output was

Input File Path:??��??�\

How can I rectify this?

回答1:

Eclipse is reading from the Console which is set by default as UTF-8. To read the data you need to change the console encoding to Japanese supported encoding.

In the Run Configuration, change the encoding to Japanese supported encoding and try again.

Your code is correct, only issue is you are reading utf-8 and then converting it to Shift_JIS which prints junk characters.

Have you tried using this.

Scanner sc = new Scanner(System.in,"utf-8");
System.out.println("Encoding is :" + Charset.defaultCharset());

System.out.println("Enter the path:");
String inputFilePath = sc.nextLine();
System.out.println("Input path:" + new String(inputFilePath.getBytes("utf-8")));

Hope this helps !!

This Answer for Chinese

Every String is already (conceptually) a sequence of characters, including Chinese characters.. Encoding only comes into it when you need to convert it into a bytes, which you don't need to for your assignment. Just use the String's hashcode. In fact, when you create a HashMap, that's exactly what will happen behind the scene
