You may use the charAt method which receives an integer index as a parameter and returns the character in the String that's positioned at that index.\n\nString s = "Hello";\nSystem.out.println(s.charAt(0)); =>This would print the H\n\nThe toCharArray method would convert the String to an array of characters containing the same characters as those in the String.\n\nchar[] C=s.toCharArray(); => C{'H','e','l','l','o'}

Have you tried getting the object as a FileInfo or something like that and then checking the type based on that?\nThats the best I can think of.

The Integer class includes a method named parseInt() that serves just this purpose. An example of a simple program that performs this conversion is shown below:\n\n\npublic class s2i {\n\n   public static void main (String[] args) {\n\n      // String s = "fred";    // do this if you want an exception\n\n      String s = "100";\n\n      try {\n         int i = Integer.parseInt(s.trim());\n         System.out.println("int i = " + i);\n      } catch (NumberFormatException nfe) {\n         System.out.println("NumberFormatException: " + nfe.getMessage());\n      }\n\n   }\n\n}\n\n\n\nOther notes\n\nInteger.toString(int i) is used to convert in the other direction, from int to String. \n  \nIf you're interested in converting a String to an Integer object, use the valueOf() method of the Integer class instead of the parseInt() method.

Something like this maybe:\n\n Runtime.getRuntime().exec("C:" + pathSeparator +\n"jdk1.3.1" + pathSeparator + "bin" + pathSeparator + "javac.exe " + file);  } catch(Exception e)  { e.printStackTrace();  }  }  }

TO_NUMBER: converts a character value expressing a number to a number datatype.\n\nSyntax: \nTO_NUMBER(char)\n\nExample:\nUPDATE <tablename> SET salary = salary + TO_NUMBER(SUBSTR('$100',2,3));\n\nOutput:\n10 rows updated.\n____________________________________-\nTO_CHAR: converts a value of a number datatype to a character datatype, using the optional format string. TO_CHAR() accepts a number(n) and a numeric format(fmt) in which the number has to appear. If fmt is omitted, 'n' is converted to a char value exactly long enough to hold all significant digits.\n\nSyntax:\nTO_CHAR (n[,fmt])\n\nExample:\nSELECT TO_CHAR(17145,'$099,999') "Char" FROM DUAL;\n\nOutput:\nChar\n- - - - - - - - - - - -\n$017,145\n\n[Look, I've given u the examples from my previously done queries, if u find any difficulty, u can mail me].

Try it out - you need a semicolon at the end of the first print statement for it to compile.\nIn java,\nit prints out:\n0000000000\n0123456789\n0246802468\n0369258147\n0482604826\n0505050505\n0628406284\n0741852963\n0864208642\n0987654321

Manipulate the inputs using vbscript.\n\nLinked page...\nLog_Type\n=Trim(Request.Form("Log_Type")) \nor\n=Trim(Request.QueryString("Log_Type"))\n\nMain page...\n<form>\n<input type=text name="Log_Type " value=" "> <=%Log_Type%>\n</form>

There is Window Object which can be used to check the text copied to the Buffer.\nThe keyword through which you can get the text at buffer is  window.clipboardData.getData('Text').\n<script>\nfunction test(){\nvar t= window.clipboardData.getData('Text');\nif(t.length > 100)\n  alert("greater then 100 characters in your buffer");\nelse\n  alert("allowed to do whatever you want");\n}\n</script>\n\nUse this javascript onpaste method.Few more things you may have to do , as onpaste may not always .

The best possible way would be to use some type of regular expression (or something similar) that will parse the input for accepted character (far too many character that should not be allowed, so search for one that are allowed)....alternately you could escape the entire input so that no matter how it's displayed the javascript will never be rendered.

My guess is that you are trying to use this method to find out if  a character is a letter or a digit. The name of the method is wrong. and the wya you are using it might be wrong too. It is Character.isLetter(...) or Character.isDigit(...) Hope that helps\n\n\nChiney

int main()\n{\n   int age, feet, inches, pounds;\n   string hair, eye;\n}\n\n\nint means integer, string is something like "brown", "mary had a little lamb", etc\nyou can also do char to define a letter varible, or char can be used as a string by declaring a character array.

According to the spec, you simply aren't allowed to do it.  There is no escape sequence that will allow you to put those characters in.  Wouldn't surprise me though if some DOM implementations support this, but then you wouldn't have well formed xml anymore.
