Encodes this String into a sequence of bytes using the given java.nio.charset.Charset charset , storing the result into a new byte array.

Usage

From source file:Main.java

public static void main(String[] args) throws UnsupportedEncodingException {
    String s = "Hello world";
    byte[] b = s.getBytes("US-ASCII");
    System.out.println(Arrays.toString(b));
}

From source file:Main.java

public static void main(String args[]) throws Exception {
    String s = "0123456789";
    byte ptext[] = s.getBytes("UTF8");
    for (int i = 0; i < ptext.length; i++) {
        System.out.print(ptext[i] + ",");
    }/*  w w w .j a v  a 2s . c o  m*/
}

From source file:Main.java

public static void main(String[] args) throws Exception {

    byte[] digest = mac.doFinal(utf8);

    String digestB64 = new sun.misc.BASE64Encoder().encode(digest);
    System.out.println(digestB64);
}
