Unicode characters / static non static access

stay java Non static methods and non static variables cannot be used in static methods in . However, static variables can be used in non static methods

public class Arraytest{
    int a[] = new int[6];
    public static void main ( String arg[] ) {
        System.out.println ( a[0] );
    }
}

So do you have any impulse to see this code ?

In short , The character stream is obtained by parsing the byte stream according to the encoding set required by the byte stream

It can be understood as Character stream = Byte stream + Encoding set (Unicode character )
