String to int

[knot Ade]

Hi,
I am trying to covert a String to its ascii value. but nothing seems to work.
I tried:
int value = Integer.valueOf(c).intValue();
where c is a String object or variable.
I also tried:
int value = (int)c;
where c is a char.
They both don't work, i get errors saying can not cast String to int.

You should convert your string to a byte array.

A String doesn't have an ASCII value. It has a series of characters which have ASCII values. (I assume by ASCII value you mean numeric value; technically it's only ASCII if it's in the range 0-127, or 0-255 for one of various extended ASCII forms.) The simplest way to get this is (copied from a neighboring thread):
<code><pre>
public static void showCharValues(String input) {
int length = input.length();
for (int i = 0; i < length; i++) {
char c = input.charAt(i);
System.out.println("Character " + i + " = " + (c && 0x0000FFFF)
+ " (hex " + Integer.toHexString(c) + ") = (\'" + c + "\')");
}
}
</pre></code>

Thanks Jim, it worked.
