Java PushbackInputStream skip() Example
PushbackInputStream class skip() method example. This example shows you how to use skip() method.
Syntax is : public long skip(long n) throws IOException
This method skips over and discards n bytes of data from this input stream. The skip method may, for a variety of reasons, end up skipping over some smaller number of bytes, possibly zero. If n is negative, no bytes are skipped.
Here is the code.
/**
* @(#) SkipPushbackInputStream.java
* A class representing use of method skip() of PushbackInputStream
class in java.io Package.
* @Version 10-June-2008

import java.io.*;
public class SkipPushbackInputStream {
public static void main(String[] args) throws IOException {
// Declare the byte array.
byte[] byteArray = new byte[]{'M', 'A', 'H', 'E', 'N', 'D', 'R', 'A'};
File file = new File("Mahendra.txt");
// Create object of FileOutputStream class for specified file.
FileOutputStream fOutStream = new FileOutputStream(file);
fOutStream.write(byteArray);
// Create object of PushbackInputStream class for specified stream.
InputStream inStream = new FileInputStream(file);
PushbackInputStream pushInStream = new PushbackInputStream(inStream);
System.out.print("\nElements read from the file stream : ");
for (int i = 0; i < byteArray.length; i++) {
if (i == 4) {
long skip = pushInStream.skip(3);
System.out.print("\nAfter skip " + skip + " elements of file "
+ " Stream next elements are : ");
i = i + 3;
}
System.out.print((char) pushInStream.read());
}
}
} |
output of the program.
Elements read from the file stream : MAHE
After skip 3 elements of file Stream next elements are : A |
