import java.io.*;
public class ReadyCharArrayReader {
public static void main(String[] args) throws IOException{
try{
char[] buffer = {'M','A','H','E','N','D','R','A'};
System.out.print("given character buffer is : ");
for (int i=0;i<buffer.length ;i++ ){
System.out.print(buffer[i]);
}
// Create object of CharArrayReader class
CharArrayReader obj = new CharArrayReader(buffer);
// ready() method call.
boolean bool = obj.ready();
System.out.println("\nThis stream is ready to be read...? " + bool);
obj.close();
System.out.println("Buffer stream is close now.");
bool = obj.ready();
}
catch (IOException e) {
System.out.println("Charcater buffer is not ready to read.");

length or buf.length-offset, whichever is smaller.
Parameters:
buf - Input buffer (not copied)
offset - Offset of the first char to read
length - Number of chars to read
Throws:
IllegalArgumentException - If offset is negative or greater than
buf.length, or if length is negative, or if the sum of these two values
is negative. */ |
