Message:

CharAt()...and indexOf()....and Arrays

Posted by peter on November 10, 2001 at 12:41 PM

I'm new to programming and I'm writting a program..that is supposed to capture the value...command line... a user inputs and checks that word for all the characters and displays them as an array...

i.e. java CommandLine "all java applications contains a static main method."

produces
letter Freq
===== ===
a 9
c 3
d 1
e 1
h 1
i 5
j 1
l 3
m 2
n 4
o 3
p 2
s 3
t 5
v 1
others 10

The code I have so far...
class CommandLine{

// MY PROBLEM HOW TO USE THE STRING ATTRIBUTES AND ARRAY ATTRIBUTES
// so how would i implement it in this method?
//This being a class that gets the value the user entered as a
command line arguments........
public int [] freq(String s)
{

for(int i = 0; i
char chr = s.charAt(i);//returns char value
int indexOf = s.indexOf(i); //returns position....

What should I do before I can call the method to main?????
Anyone have ideas...
