Hi !
I have some problem with that howework.
I must finish it before tomorrow and I am getting crazy !
I've just created the two files (see the code).
I tried different codes but I still don't get the file in upper case.
Can anyone help me, please !
Thanks in advance
import java.io.*;

public class ChangeToUpperCaseInputStream extends FilterInputStream {
//Creates a new instance of ChangeToUpperCaseInputStream
public ChangeToUpperCaseInputStream(InputStream in){
super(in);
}
/* 1st try
public int read() throws IOException {
int result = super.read();
return (result == -1)? result : Character.toUpperCase((char)result);
} */
// 2nd try
public int read() throws IOException {
int b = in.read();
if (b != -1) {
b= Character.toUpperCase(b);
}
return b;
}
public int read(byte[] b) throws IOException {
int len;
len = in.read(b, 0, b.length);
if (len != -1) {
for (int i=0; i<len; i++)
b[i]= (byte) Character.toUpperCase (b[i]);
}
return len;
}
public int read(byte[] b, int off, int len) throws IOException {
len = in.read(b, off, len);
if (len != -1) {
for (int i=off; i<(off+len); i++)
b[i]= (byte) Character.toUpperCase (b[i]);
}
return len;
}
}
