import java.io.*;
public class filesinputoutput {
public static void main(String[] args) {
String obj = "abc";
byte b[] = obj.getBytes();
ByteArrayInputStream obj1 = new ByteArrayInputStream(b);
for (int i = 0; i < 2; ++ i) {
int c;
while ((c = obj1.read()) != -1) {
if (i == 0) {
System.out.print(Character.toUpperCase((char)c));
obj2.write(1);
}
}
System.out.print(obj2);
}
}
}
