I'm trying to run a simple servlet that counts the number of times a user visits the page using cookies but I'm getting the following error. I thought that NullPointerException was because there were no cookies at all in the browser. But after checking I found a couple of cookies …

Even after setting all the paths correctly, I get an error saying the "setclasspath.sh" cannot be found. I checked the directory and it was there. I then changed the permissions using chmod +x setclasspath.sh but to no avail. I've changed the permissions of all the files inside the "bin" directory …

So, I wrote the following program to connect to my local mysql server and create a table in the existing "test" database. The program compiled without any errors, but I got the following run-time error: java.sql.SQLException: Cannot connect to MySQL server on localhost:3306. Is there a MySQL server running on …

So I know of two methods of reading or writing files in java. The first is the read(byte[]) method provided by InputStream class. The second is the readLine or write() method provide by the Buffered prototype. Which is the more efficient one out of these? Which one would you recommend?

In addition to BufferedReader, you also have the option of using read(byte[]) function. It is relatively faster than BufferedReader.

Instead of double amounts[] = {0,100,200,300,400,500,600,700,800,900,1000,25000}; Try this, double amounts[] = new double[30]; amounts[] = {0,100,200,300,400,500,600,700,800,900,1000,25000}; Good Luck.

Isn't it better to use the BufferedReader function readLine() instead of read() or read(byte[])? The reason I ask is because of potential memory wastage by the read() function. If I specify a byte array of size 10, then it will become capable of accepting ten bytes from the transmitter. However, …
