int[] a1 = new int[10];
String[] a2 = {"one", "two", "three"};
String[] a3 = Arrays.copyOf(a2, 3); // copy 1 array to another array

a1[0] = 1;
Arrays.fill(a1, 2);     // fill a1 array with 2's in all indices
System.out.println(a1[2]);
System.out.println(a1.length);  //array.length
System.out.println(Arrays.equals(a2, a3));  //true

// construct array with range function
int[] oneTo10 = IntStream.rangeClosed(1, 10).toArray();    // convert IntStream to array w/ toArray()
for (int x: oneTo10) {
    System.out.print(x);
}
System.out.println(Arrays.binarySearch(oneTo10, 9));   // 8 - the index of 9

int a4[][] = new int[2][2];
String[][] a5 = {{"00", "01"},
                 {"01", "11"}};
