See the API doc at
The methods
Character.codePointCount(char[],int,int)
and
Character.codePointAt(char[],int)
are all you need.
Thank you Thomas. I'll post what I have.
I will appreciate any comments.
Ah, I see what you're trying to do. Although, unless this is for a
class (school assignment), I think Thomas's suggestion would be the best.
There might be a pithier way to do this with Charset, NIO Buffer class,
CharsetEncoder and CharsetDecoder. I'm not really good enough with
foreign character sets to know how though. (Note the commented out code
lists Charsets, which includes several varieties of UTF-32.)
public class CharsetTest {
static int [] ctoUTF32( char [] buf ) {
String temp = new String( buf );
int len = temp.codePointCount( 0, temp.length() );
int [] utf32 = new int[ len ];
for( int i = 0; i < len; i++ ) {
utf32[i] = temp.codePointAt( i );
}
return utf32;
}
/**
* @param args the command line arguments
*/
public static void main(String[] args) {
char [] test = { '0', 'z', '\t', '}' };
int [] intchars = ctoUTF32( test );
for( int i : intchars ) {
System.out.println( i );
}
// TODO code application logic here
// Map<String, Charset> cs = Charset.availableCharsets();
// Set<String> keys = cs.keySet();
// for( String name : keys ) {
// System.out.println( name );
// }
}
}
Fortunately I'm not concerned with character sets here.
