Usage

From source file:Main.java

public static void main(String[] argv) throws Exception {
    int[] ints = (int[]) Array.newInstance(int.class, 10);
}

From source file:Main.java

public static void main(String[] argv) throws Exception {
    int[] ints = (int[]) Array.newInstance(int.class, 10);

    String[] stringArray = (String[]) Array.newInstance(String.class, 10);
}

From source file:MainClass.java

public static void main(String args[]) {
    Object array = Array.newInstance(int.class, 3);

    int length = Array.getLength(array);
    for (int i = 0; i < length; i++) {
        int value = i;
        Array.setInt(array, i, value);
    }//from   w  ww. jav  a  2 s  . co m

    for (int i : (int[]) array) {
        System.out.println(i);

    }
}

From source file:Main.java

public static void main(String[] argv) throws Exception {
    int[][] ints2 = (int[][]) Array.newInstance(int.class, new int[] { 10, 20 });
}

From source file:Main.java

public static void main(String[] argv) throws Exception {
    int[][] ints2 = (int[][]) Array.newInstance(int[].class, 10);
}

From source file:MainClass.java

public static void main(String args[]) {
    int[] array = (int[]) Array.newInstance(int.class, 3);

    for (int i = 0; i < array.length; i++) {
        array[i] = i;//from   w  w w .j  av a  2  s.  c  o m

    }

    int[] arrayDoubled = (int[]) doubleArray(array);

    for (int i : arrayDoubled) {
        System.out.println(i);
    }
}

From source file:Main.java

public static void main(String[] argv) throws Exception {
    int[] array = { 1, 2, 3 };
    Object newArray = Array.newInstance(array.getClass().getComponentType(), Array.getLength(array) * 2);
    System.arraycopy(array, 0, newArray, 0, Array.getLength(array));

}

From source file:MainClass.java

public static void main(String args[]) {
    Object array = Array.newInstance(int.class, 3);
    printType(array);// ww w.  j  a  v  a 2s  . co m
    fillArray(array);
    displayArray(array);
}

From source file:MainClass.java

public static void main(String args[]) {
    int dimensions[] = { 3, 4 };
    int array[][] = (int[][]) Array.newInstance(int.class, dimensions);

    for (int[] inner : array) {
        for (int i : inner) {
            System.out.println(i);
        }//from   ww  w.ja va  2 s .co  m
    }
}

From source file:MainClass.java

public static void main(String args[]) {
    Object array = Array.newInstance(int.class, 3);

    Class type = array.getClass();
    if (type.isArray()) {
        Class elementType = type.getComponentType();
        System.out.println("Array of: " + elementType);
        System.out.println("Array size: " + Array.getLength(array));
    }/*from  w w  w. j  a  v  a2 s  . c o m*/
