Need help w/ java class

No, that will take the string as is. You will need 7 indexof statements.

int foundSymbol = password.indexOf("!);
int foundSymbol = password.indexOf("@);
int foundSymbol = password.indexOf("#);
int foundSymbol = password.indexOf("$);
int foundSymbol = password.indexOf("%);
int foundSymbol = password.indexOf("^);
int foundSymbol = password.indexOf("/&);
int foundSymbol = password.indexOf("*);
if(foundSymbol >=0)



Like that? Oh and I just realized I need to add equals.ignoreCase somewhere

Not quite that will only test the last one. You are resetting your variable each time, then only testing the last time.

It gave me a compile error anyways. If i have to have seperate indexOf statements for the special characters how would I go about putting those together? Obviously the !@#$%^&* wont work together as one whole string.

Try this(my java is rusty so it might not work):

Code: Select all

int foundSymbol = 0
int foundSymbol = foundSymbol + password.indexOf("!") + 1;
int foundSymbol = foundSymbol + password.indexOf("@") + 1;
int foundSymbol = foundSymbol + password.indexOf("#") + 1;
int foundSymbol = foundSymbol + password.indexOf("$") + 1;
int foundSymbol = foundSymbol + password.indexOf("%") + 1;
int foundSymbol = foundSymbol + password.indexOf("^") + 1;
int foundSymbol = foundSymbol + password.indexOf("/&") + 1;
int foundSymbol = foundSymbol + password.indexOf("*") + 1;
if(foundSymbol  > 0){}

So that I am doing is setting foundSymbol to 0. If index of does not find the character in the string it returns -1. -1 + 1 = 0. Then if one of them hits in the index it will return a 1 or greater. So if foundSymbol is larger than 0 you contain one of the characters.

You also forgot the closing quotes in your string.

Same error I've been getting with the multiple indexOf.

java:45: error: variable foundSymbol is already defined in method main(String[])

but I got like 8 of those, 45 and up.

After struggling and contacting the teacher numerous times I ended up submitting an assignment that didnt run and wasnt finished, i still managed to get an 80/100 though. Thanks for the help. This week he provided us with some sample code and all we have to do is add to it in order to complete the program, much easier!
