java _io_ file input character stream

No character stream reads data garbled
byte stream data may be read because of the different character sets, each character corresponding to the character size different from
the garbled /

Read read = new FileReader (File f); or path

Operation:
In addition to selecting and changing the flow of the byte array into a character array, the other are the same

public class test{
    public static void main(String[]args)
    {
        File f =new File("C:/Users/10853/eclipse-workspace/hell/src/hell/abc");
        Reader reader=null;
        try {
        reader=new FileReader(f);

        **char[] flush =new char[1024];**
        int len=-1;
        try {
            while((**len=reader.read(flush))!=-1**)
            {//字符数组-->字符串
                **String s=new String(flush,0,len);**
                System.out.println(s);
            }
        } catch (FileNotFoundException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
    }catch(IOException e)
    {
        e.printStackTrace();
    }finally {
        try {
            if(null!=reader)
            {
                reader.close();
            }
        }catch(IOException e)
        {
            e.printStackTrace();
        }
