Answer 1

DataInputStream in = new DataInputStream(System.in);

Answer 3

大哥不行也！我试了一下，
import java.io.DataInputStream;public class t {
    public static void main( String[] args ) {
     DataInputStream dis = new DataInputStream( System.in );
    
     short s, j;
    
     try {
     System.out.print( "s? " );
         s = dis.readShort();
         System.out.print( "j? " );
         j = dis.readShort();
        
         System.out.println( "s = " + s + "j = " + j );
      } catch ( Exception e ) {
      System.out.println( "an error occured" );
      }
    }

}
结果不对啊！

Answer 4

public String readConsole() throws Exception 
   {
      // Create a buffered reader with System.in, then
      // read a line from it.
      BufferedReader breader;
      breader = new BufferedReader(new InputStreamReader(System.in));
      return breader.readLine();
   }

Answer 5
