You need to escape backslashes as .

 System.out.printf ("%c /\\",ch);

You can see more information about it here.

Few comments :

  1. You used "%s" for characters, you can use "%c for characters. See formatting tutorial.
  2. You did not close the scanner, you will get so warning. You should close it using Scanner.close() method.
  3. Last curly brace } is remaining.

Backslashes needs to be escaped: - 

System.out.printf ("%c /\\",ch);

And you can change your: - switch ( ch ) to switch(Character.toLowerCase(ch)), to avoid having cases for both A and a. Just use case 'a':

This should work for you;

System.out.printf ("%s '/\\'",ch);

System.out.printf ("%s /\\",ch);

Instead of System.out.printf ("%s /\",ch);

 Escape Sequence    Description
 \t     Insert a tab in the text at this point.
 \b     Insert a backspace in the text at this point.
 \n     Insert a newline in the text at this point.
 \r     Insert a carriage return in the text at this point.
 \f     Insert a formfeed in the text at this point.
 \'     Insert a single quote character in the text at this point.
 \"     Insert a double quote character in the text at this point.
 \\     Insert a backslash character in the text at this point
