What is the difference between InputStreamReader and BufferedReader?
InputStreamReader is used to convert data from an input stream into a character stream, while BufferedReader is used to read characters from a character stream. InputStreamReader is used to bridge the difference between bytes and characters, allowing programs to access characters from a byte stream, while BufferedReader is used to wrap another Reader and provide an efficient buffering to it.The default buffer size of a BufferedReader in Java is 8192 bytes.A BufferedReader can be used in a snippet to read text from an input stream such as a file, network connection, or string. It is most often used in conjunction with an InputStreamReader which turns the input into characters that can be read from the BufferedReader.
For example, a snippet of code to read a file line by line may look like this:
try (BufferedReader reader = new BufferedReader(new InputStreamReader(new FileInputStream(file)))) {
String line;
while ((line = reader.readLine()) != null) {
// process the line
}
} catch (IOException e) {
e.printStackTrace();
}
How to repair corrupted hard disk?
1. Run Disk Check: The first step to repairing a corrupted hard disk is to run the Windows built-in disk checking utility. This will check for errors on your hard disk and try to fix them. To do this, open up Windows Explorer and right-click on the drive you want to check. Select Properties and then Tools. In the Error-checking section, click “Check Now.”
2. Use a Professional Data Recovery Software: If the disk checking utility fails to fix the corrupted disk, you may need to use a professional data recovery software. These programs are designed to scan your hard disk and find any lost or corrupted data. Once found, they can then repair the corrupted files and recover your data.
3. Reimage the Drive: As a last resort, you may need to reimage the drive. This means you will overwrite all existing data on the drive with a fresh, uncorrupted installation of the operating system. This will usually fix any corrupted files or settings, but you will lose all data stored on the drive.
What is the perfect golf grip?
The perfect golf grip is a personal preference, and will depend on a variety of factors, such as hand size, handedness, and swing style. Generally, the ideal grip is a neutral grip – with the right hand slightly weaker than the left – that places the hands on the club in such a way that allows for a reoccurring, consistent swing over the course of time.
