Another array issue
I keep getting <identifier> expected when I try to compile the program below. Not sure what I've missed.
import java.io.*;
import java.util.*;
publicclass TestScores{
staticfinalint MAX_SCORE = 200;
staticfinalint CATEGORY_DIFFERENCE = 25;
publicstaticvoid main(String[] args)throws FileNotFoundException{
int[] categories =newint[MAX_SCORE/CATEGORY_DIFFERENCE];
Scanner inFile =new Scanner(new FileReader("testscores.txt"));
while(inFile.hasNext()){
int score = inFile.nextInt();
categories[(score==MAX_SCORE)?categories.length-1:score/CATEGORY_DIFFERENCE]++;
}
inFile.close();
for(int i=0,int min=0;i<categories.length-1;i++){
System.out.printf("Scores between [%d, %d] = %d%n",min,(min+=CATEGORY_DIFFERENCE)-1,categories[i]);
}
System.out.printf("Scores between [%d, %d] = %d%n",MAX_SCORE-CATEGORY_DIFFERENCE,MAX_SCORE,categories[categories.length-1]);
}
}

should be:
for(int i = 0, min = 0; i >< categories.length - 1; i++){
(Notice there's a bug in the forum software to print a less-than as a greater-thanless-than.)

How many time need it be said?
When you get an error, include the EXACT error message DO NOT paraphrase. The error message will also give you a line number. Please indicate the line of code. We do not want to count, especially if the code is several hundred lines of code long and/or your post does not include all the code.
Still get <identifier> expected when I try to compile it.
Do you go to the doctor and say "I'm sick" and expect him to cure you?
DETAILS!
Z:\java\TestScores.java:18: <identifier> expected
for(int i=0,min=0,int i>categories.length-1, int i++){
^
Z:\java\TestScores.java:22: illegal start of expression
}
^
Z:\java\TestScores.java:21: ';' expected
System.out.printf("Scores between [%d, %d] = %d%n",MAX_SCORE-CATEGORY_DIFFERENCE,MAX_SCORE,categories[categories.length-1]);

Sorry, I was using BlueJ and it doesn't give full errors.
Compilers are smart. Once you have told them what type a variable is, you do not have to keep reminding them.
for(int i=0,min=0,int i>categories.length-1, int i++){
BTW the above code is different to the code in your first post. You really do expect us to read your mind.
Don't use a worsened code. Use your initial code and apply reply #1.

With reply one suggestion applied, I still get:
Z:\java\TestScores.java:18: <identifier> expected
for(int i=0,min=0,int i>categories.length - 1, int i++){
^
Z:\java\TestScores.java:22: illegal start of expression
}
^
Z:\java\TestScores.java:21: ';' expected
System.out.printf("Scores between [%d, %d] = %d%n",MAX_SCORE-CATEGORY_DIFFERENCE,MAX_SCORE,categories[categories.length-1]);

For beginners, use the console.
FFS. Tell me what is wrong with this code.
String s = "Hello";
System.out.println(String s);

It's clearly telling you what to do. Read the error message. It says ; expected. Where do you think in that for statement you would need to use ' ; ' ?Now make the necessary changes.
You need this
http://java.sun.com/docs/books/tutorial/
System.out.println(s);
FFS. Tell me what is wrong with this code.
String s = "Hello";
System.out.println(String s);

You still use the worsened version of the code. I have said don't use it.
hiwaa at 2007-7-29 12:35:34 >
and? You cannot apply the same logic and determine what is wrong with your code?
hiwa I used what you said in reply 1.
> hiwa I used what you said in reply 1.
And at the same time you didn't use the code you have posted in your main reply.
Remove the fucking int from in front of the fucking i. Is that plain enough for you?
BTW the i in the conditional and incremental statements not the initialisation statement. Do you understand what that means?
Doh! Sorry for aggrevation. I've been doing this for too long tonight. It is working now. Thanks.
Yes I understand. I've been doing this for 4 weeks, gimme a break. ****.
We did give you a break but it still took 20 replies for you to understand your mistake. The human brain has several billion neurons (or brain cells) and it is expected that you use ony a few of them and think for yourself.
Oh and before you get all offended and make some reply, I saw this quote recently:
Little minds are wounded by the smallest things
Yeah..... anyways, thanks for the help. I do appreciate it.
