Interesting language (looks a lot like Scala!), serviceable reference. Many of the dispatch objects don't really need explicit invalidation, such as groups or queues, because they become inactive by the sheer fact of you stopping using them. Charset; public class TestCharsetEncodeByteBuffer { public static void main(String[] args) { byte[] bytes = {0x00, 0x48, 0x00, 0x69, 0x00, 0x2C, 0x60, (byte)0xA8, 0x59, 0x7D, 0x00, 0x21}; // "Hi,您好!" // Print UCS-2 in hex codes System.out.printf("%10s: ", "UCS-2"); for (int i = 0; i < bytes.length; ++i) { System.out.printf("%02X ", bytes[i]); } System.out.println(); Charset charset = Charset.forName("UTF-8"); // Encode from UCS-2 to UTF-8 // Create a ByteBuffer by wrapping a byte array ByteBuffer bb = ByteBuffer.wrap(bytes); // Create a CharBuffer from a view of this ByteBuffer CharBuffer cb = bb.asCharBuffer(); ByteBuffer bbOut = charset.encode(cb); // Print hex code System.out.printf("%10s: ", charset.name()); while (bbOut.hasRemaining()) { System.out.printf("%02X ", bbOut.get()); } System.out.println(); // Decode from UTF-8 to UCS-2 bbOut.rewind(); CharBuffer cbOut = charset.decode(bbOut); System.out.printf("%10s: ", "UCS-2"); while (cbOut.hasRemaining()) { char aChar = cbOut.get(); System.out.printf("'%c'[%04X] ", aChar, (int)aChar); // Print char & hex code } System.out.println(); } } UCS-2: 00 48 00 69 00 2C 60 A8 59 7D 00 21 UTF-8: 48 69 2C E6 82 A8 E5 A5 BD 21 UCS-2: 'H'[0048] 'i'[0069] ','[002C] '您'[60A8] '好'[597D] '!'[0021] As mentioned, Java internally stores characters (char type) in 16-bit UCS-2 character set.

For instance, if you add a number to an item consisting of text (a string), the number is converted to text. Most integers, for example 20, don't have an integer for a square root. 5 is too big to be the square root of 20, and 4 (whose square is 16) is too small.

Atari800: Atari 8-bit computer emulator by Dave Firth. It is extensible because it allows the users to define their own XML elements. Programs are documented by the syntax and are all but ligthweight... Clear the screen as follows: and type The computer has not forgotten the stored statement. For example, the above example can be re-written in a much neater manner as follow: import java.io.*; public class FileCopyNoBufferJDK7 { public static void main(String[] args) { String inFileStr = "test-in.jpg"; String outFileStr = "test-out.jpg"; long startTime, elapsedTime; // for speed benchmarking // Check file length File fileIn = new File(inFileStr); System.out.println("File size is " + fileIn.length() + " bytes"); // "try-with-resources" automatically closes all opened resources. try (FileInputStream in = new FileInputStream(inFileStr); FileOutputStream out = new FileOutputStream(outFileStr)) { startTime = System.nanoTime(); int byteRead; // Read a raw byte, returns an int of 0 to 255. while ((byteRead = in.read()) != -1) { // Write the least-significant byte of int, drop the upper 3 bytes out.write(byteRead); } elapsedTime = System.nanoTime() - startTime; System.out.println("Elapsed Time is " + (elapsedTime / 1000000.0) + " msec"); } catch (IOException ex) { ex.printStackTrace(); } } } Example 2: Copying a file with a Programmer-Managed Buffer. import java.io.*; public class FileCopyUserBuffer { // Pre-JDK 7 public static void main(String[] args) { String inFileStr = "test-in.jpg"; String outFileStr = "test-out.jpg"; FileInputStream in = null; FileOutputStream out = null; long startTime, elapsedTime; // for speed benchmarking // Check file length File fileIn = new File(inFileStr); System.out.println("File size is " + fileIn.length() + " bytes"); try { in = new FileInputStream(inFileStr); out = new FileOutputStream(outFileStr); startTime = System.nanoTime(); byte[] byteBuf = new byte[4096]; // 4K byte-buffer int numBytesRead; while ((numBytesRead = in.read(byteBuf)) != -1) { out.write(byteBuf, 0, numBytesRead); } elapsedTime = System.nanoTime() - startTime; System.out.println("Elapsed Time is " + (elapsedTime / 1000000.0) + " msec"); } catch (IOException ex) { ex.printStackTrace(); } finally { // always close the streams try { if (in != null) in.close(); if (out != null) out.close(); } catch (IOException ex) { ex.printStackTrace(); } } } } This example again uses FileInputStream and FileOutputStream directly.

I think it is really exciting to open it up to a wide range of developers, which presents greater opportunity across the board." But Objective-C is over 30 years old at this point, and Swift is an effort to modernize it to make apps easier to write and run faster. Also, make sure that the three Blues are distinct. Don't rely on that occurring if you want to be portable. (Use gettimeofday() if you need to track time elapsed.
