java equilant for charAtCode

i had that problem as well. all i got was bunch of chinese results lol. newhose..i found out that it basically just translates to a decimal equilant. so in java i did

char ch = 'd';

System.out.pritnln("charAtCode = " + (int) ch);

however, now i've run into a bigger problem :(. in JS there is a function

parseInt (string, radix);

..so if i have parseInt ("blah blah balh", 16); it will return result in base 16.

how the heck would i do THAT in java!!

Let's get really adventurous and try

[url=http://java.sun.com/javase/6/docs/api/java/lang/Integer.html#parseInt(java.lang.String, int)]http://java.sun.com/javase/6/docs/api/java/lang/Integer.html#parseInt(java.lang.String, int)[/url]

As for the original question, I think you're talking about the charCodeAt method, which is equivalent to Java's charAt method. JavaScript also has a charAt method, but it returns a one-character-long string, since JS doesn't have a char data type.

> ne suggestions?

My first suggestion is that you use standard English: "any" instead of "ne", "I don't know" instead of "idk", etc.. Communication can be difficult enough around here; we should all at least try to speak the same language.

Looks like the main challenge is keeping track of when things should be treated as strings and when they're supposed to be ints or chars. You can't call methods like toString() on a Java primitives, so you'll need to do something else, like wrapping the expression in a call to String.valueOf(). Even in those cases where the toString() is implicit, you may need to help it along. For instance, this line var mult = parseInt(prand.charAt(sPos) + prand.charAt(sPos*2)

+ prand.charAt(sPos*3) + prand.charAt(sPos*4) + prand.charAt(sPos*5));

could be translated to int mult = Integer.parseInt("" + prand.charAt(sPos) + prand.charAt(sPos*2)

+ prand.charAt(sPos*3) + prand.charAt(sPos*4) + prand.charAt(sPos*5));

Adding the empty string at the beginning forces the expression to be treated as a string instead of an integer. But in the case of var prand = "";

for (var i=0; i < pwd.length; i++) {

prand += pwd.charCodeAt(i).toString();

}

you want to do just the opposite. Assuming I'm reading it correctly, this loop creates a new string in which each character of the original is replaced with a string representation of the numeric encoding of the character. That means you have to force Java not to treat the individual characters as chars. The most direct translation would be String prand = "";

for (int i = 0; i < pwd.length(); i++) {

prand += (int)(pwd.charAt(i));

}

Later, you'll need to do a similar coercion as you translate enc_str += String.fromCharCode(enc_chr);

to enc_str += (char)enc_chr;

I assume you've already shot the guy who wrote the JS, and that's why you aren't forcing him to do this translation. ^_^
