Java Program to mark the current position in this input stream
The method java.io.InputStream.mark() is used to mark the current position in this input stream. This method requires a single parameter i.e. the bytes that can be read before the position marked is invalidated.
A program that demonstrates this is given as follows −
Example
import java.io.FileInputStream;
import java.io.InputStream;
public class Demo {
public static void main(String[] args) throws Exception {
InputStream i = null;
try {
i = new FileInputStream("C://JavaProgram//data.txt");
System.out.println("Char : "+(char)i.read());
System.out.println("Char : "+(char)i.read());
System.out.println("Char : "+(char)i.read());
i.mark(0);
System.out.println("Char : "+(char)i.read());
System.out.println("Char : "+(char)i.read());
if(i.markSupported()){
i.reset();
System.out.println("Char : "+(char)i.read());
System.out.println("Char : "+(char)i.read());
}
} catch(Exception e) {
e.printStackTrace();
}
}
}The output of the above program is as follows −
Output
Char : D Char : A Char : T Char : A
