for(File f : filesInDirectory)


Got null point exception in these two lines

Any suggestion please

you might have got that because your parent directory may be empty...incase if the parent directory is not empty please tell about the contents in parent directory...!!!

First check for indexOf(".") if it returns true then check for LastIndexOf(".")

More precisely, what will x be in that case, and what will be the results?

i wont think it will cause any effect as you are using only lastIndexOf

Andreas Svenkson wrote:Hi guys, I was rehearsing some stuff regarding initialization and was wondering about this code..

public class TestVars { { j = -1;} int i = j = -2; // int i = j; int j = 0; public void go() { System.out.println("i="+i+"\nj="+j); } public static void main(String[] args) { new TestVars().go(); } }

If line 3 is commented out, and line 4 is uncommented, we will get the expected "illegal forward reference" compiler error. My question is, why exactly does line 3 not cause this error?
For those interested, there is more information here: http://java.sun.com/docs/books/jls/second_edition/html/classes.doc.html#287406

I have my suspicions but still find it slightly unreasonable; because while 'j' is used on the left hand side of an assignment, it is arguably also on the right hand side.

// Andreas

line 4 won't work... It's because you cannot refrence a field before it is defined.

public class Test { static int[]given = {7,4,2,8,1,9,3,10,6,5,11}; public static void main(String[]args) { do(given); } public static void do(int[]take) { int le = 1 + (size-1)/2; int ri = size-l; TempArray ta = new TempArray(le,ri); ta.show(); } class TempArray { int[]Le; int[]Ri; TempArray(int le, int ri) { this.Le = new int[le]; this.Ri = new int[ri]; } } }

i think its because you did not declare size and TempArray variables..and another fault i see is class TempArray does not have a method named "Show"

Please re-read my response. I have explained what the 3 junk characters are and how to deal with them. To re-iterate; to understand the problem follow the link to the BOM Wikipedia site. You can either manually remove the junk characters or you can employ my much plagiarised class BOMStripperInputStream obtained by following the other link I gave.

I opened the file using UTF-8 . but now "" these characters are replaced by "?"

The characters are the BOM for utf-8. Java is very bad at dealing with BOMs and the BOM can be removed and you should then open the file using utf-8 character encoding. My class BOMStripperInputStream plagiarised on several sites can help to remove the BOM.

Actually My CSV files format is

i.e first 7 characters are numbers then separator then some text.

I am reading a CSV file using a java program.
It seems that some of the .csv files i read using my program contains junk characters, how read the contents of the file wihtout reading the junk characters?

I have String say Str it usually has a 10 digit number..how to test it contains numbers between 0-9 only

sorry, CSVformat is not specified..

Hi,

Can you Please tell me,
How to read/Import data from CSV file into JAVA file?

1) first create a copy of the orginal parent record with a new Primary key.
2) change the FK on the child record to the primary key of the new parent record you just added.
3) delete the old parent record because you dont need it any more.
4) ask your DBA why he or she would ever use as a primary key data that might need to be changed. (well ... maybe you should not ask this question)

It worked ....Thanks

Change the while loop condition as >= 1, your program will work 100%

public class BeerSong{
public static void main (String[] args){
int beerNum = 99;
String word = "bottles";

while (beerNum >= 1){

if (beerNum == 1){
word = "bottle"; // singular
}
System.out.println( beerNum + " " + word + " of beer on the wall" );
System.out.println( beerNum + " " + word + " of beer" );
System.out.println("Take one down");
System.out.println("Pass it around");
beerNum = beerNum - 1;
if (beerNum > 0){
System.out.println(beerNum + " " + word + " of beer on the wall");
}else {
System.out.println("No More bottles of beer on the wall");
}

}

}
}
