Java : Would like help in solving "programming exercises"

[murakumo32]

I would appreciate it if someone could help me. I've been given specific directions to write a "simple" program in Java, but I can't seem to get the results i desire.

Problem:
Write a program that encodes a string by replacing all letters "i" with "!" and all letters "s" with "$". Use the replace method. Demonstrate that you can correctly encode the string "Mississippi".

So I need to change "Mississippi" into "M!$$!$$!pp!", here's what I have to far:

import java.lang.String;

public class Mississippi
{
    public static void main (String[] args)
    {
        String msp = "Mississippi";
        System.out.print (msp.replace ("i" , "!"));
    }
}

Everything else I've tried wouldn't compile or didn't give me the solution I need, such as:

...
msp.replace ("i", "!");
System.out.print (msp);

Gives me "Mississippi"

or

System.out.print (msp.replace ("i" , "!") msp.replace ("s" , "$"));

I get a syntax error when compiling

or

System.out.print (msp.replace ("i" , "!");
System.out.print (msp.replace ("s" , "$");

Gives me "M!ss!ss!pp!Mi$$i$$ippi"

well the best way to actually do this is to break the string apart and read every single letter at once and check if it's an s or a i and switch the letter if necessary

of course it uses more code but should work a lot better, i could give it a try, but my last java job was a game engine which had nothing to do with strings but if you want me to, i could wrap something up

well replace should work ;P

{
   String str = "Mississippi";   //creating a string str containing "Mississippi"
   str = str.replace('i', '!');      //replacing i's with !'s and storing string in str
   str = str.replace('s', '$');    //replacing s's with $'s and storing string in str
   System.out.println(str);     //displaying str in console
}

used it like this and worked like a charm

you have to store your new string somewhere so you can modify it again, there is no way you can do this in one step.

Thanks a bunch! I'll need to keep that "str = " in mind the next time a problem like this comes up.

"str =" is nothing special, just a name for a String variable; could have named it "String HermanMunster"
