Usage

From source file:Main.java

public static void main(String[] args) {
    FloatBuffer floatBuffer = FloatBuffer.allocate(10);

    floatBuffer.put(new float[] { 1.23F, 2.13F, 3.13F, 2.13F, }, 0, 2);

    System.out.println(Arrays.toString(floatBuffer.array()));

}

From source file:Main.java

public static void main(String[] argv) throws Exception {
    byte[] ipAddr = new byte[] { 127, 0, 0, 1 };
    InetAddress addr = InetAddress.getByAddress("Localhost", ipAddr);
    System.out.println(Arrays.toString(addr.getAddress()));
}

From source file:Main.java

public static void main(String[] args) {
    Integer[] arr = { 1, 2, 3, 1, 4, 4, 1, 5 };
    System.out.println(Arrays.toString(arr));
    List<Integer> l = Arrays.asList(arr);

    System.out.println(l);/*  ww w .j av a 2  s.  co  m*/

    Set<Integer> set = new HashSet<Integer>();
    for (int j = 0; j < l.size(); j++) {
        if (Collections.frequency(l, l.get(j)) > 1) {
            set.add(l.get(j));
        }
    }
    System.out.println("dups are:" + set);
}

From source file:Main.java

public static void main(String[] args) {
    Integer[] numbers = { 1, 2, 3 };

    // watch return types, it is implied, no return keyword is necessary
    Arrays.sort(numbers, (i1, i2) -> i2 - i1);

    System.out.println(Arrays.toString(numbers));
}

From source file:Main.java

public static void main(String[] argv) throws Exception {
    String testStr = "J J@H.com";
    System.out.println("Original string: " + testStr);
    String[] result = testStr.split("[\\W && [^.@]]+");
    System.out.println(Arrays.toString(result));
}

From source file:Main.java

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

    byte[] bytes = new byte[10];
    ByteBuffer buf = ByteBuffer.allocate(10);
    buf = ByteBuffer.wrap(bytes);

    System.out.println(Arrays.toString(buf.array()));
    System.out.println(buf.toString());
}

From source file:Main.java

public static void main(String[] args) {
    List<Integer> numberList = Arrays.asList(1, 2, 3, 4, 5);
    Stream<Integer> listStream = numberList.stream();

    System.out.println(Arrays.toString(listStream.toArray()));
}

From source file:Main.java

public static void main(String[] args) {

    // initializing unsorted short array
    Short[] sArr = new Short[] { 3, 13, 1, 9, 21 };

    System.out.println(Arrays.toString(sArr));

    // create a comparator
    Comparator<Short> comp = Collections.reverseOrder();

    // sorting array with reverse order using comparator
    Arrays.sort(sArr, comp);/*from   w  w w .j a v  a2s . com*/

    System.out.println(Arrays.toString(sArr));
}

From source file:Main.java

public static void main(String[] args) {

    // initializing unsorted short array
    Short sArr[] = new Short[] { 3, 13, 1, 9, 21 };

    System.out.println(Arrays.toString(sArr));

    // create a comparator
    Comparator<Short> comp = Collections.reverseOrder();

    // sorting array with reverse order using comparator from 0 to 2
    Arrays.sort(sArr, 0, 2, comp);

    System.out.println(Arrays.toString(sArr));
}

From source file:Main.java

public static void main(String[] args) {
    CharBuffer cb1 = CharBuffer.allocate(50);
    cb1.append("java2s.com");
    cb1.rewind();//from w w  w.  j  ava 2 s.  co m

    System.out.println(cb1.charAt(2));
    System.out.println(Arrays.toString(cb1.array()));
