Attaching a Reader to a Collection

Question

i've got a Collection of Strings.
rather than iterate thru the Collection, i want to use a Reader+ to
get the data in the Collection.
how could i do that?

Answer 1

well, this is what i came up with.
turns out i did not want to use a Collection, but rather a raw String array.
public class RawArrayReader extends Reader {
    private char[] contents;
    private int position = 0;
    private int markPoint = 0;
    public RawArrayReader(String[] rawArray) {
        super();
        char[] tmp = new char[0];
        for(int i = 0; i < rawArray.length; i++) {
            String s = (String) rawArray;
char[] tmp2 = tmp;
tmp = new char[tmp.length + s.toCharArray().length + 1];
int j = 0;
while(j < (tmp.length - 1)) {
if(j < tmp2.length) {
tmp[j] = tmp2[j];
} else {
tmp[j] = s.toCharArray()[(j - tmp2.length)];
j++;
tmp[j] = " ".toCharArray()[0];
this.contents = new char[(tmp.length - 1)];
for(int i = 0; i < this.contents.length; i++) {
this.contents[i] = tmp[i];
public void close() { this.contents = null; }
public boolean markSupported() { return(true); }
public void reset() { position = markPoint; }
public boolean ready() {
if(contents == null) { return(false); }
return(true);
public void mark(int i) {
if (contents != null) {
if (i < 0) { i = 0; }
if (i < contents.length) {
markPoint = i;
} else {
markPoint = (contents.length - 1);
position = markPoint;
} else {
markPoint = 0;
position = 0;
public long skip(long n) throws IOException {
if((n + position) >= contents.length) {
throw(new IOException());
position += n;
return(n);
public int read() {
if(position >= contents.length) { return(-1); }
char c = contents[position];
position++;
return((int) c);
public int read(char[] buf) {
int x = 0;
while(x < buf.length) {
buf[x] = contents[position];
position++;
x++;
if (position >= contents.length) { return(-1); }
return(x);
public int read(char[] cbuf, int off, int len) {
int x = 0;
while(x < len) {
cbuf[off] = contents[position];
x++;
position++;
off++;
if (position >= contents.length) { return(-1); }
return(x);
}not tested this class completely. just finished it. this "seems" to work ok.
if this is a violation of how to OOP or use Java, please let me know.
help me learn this stuff.
