import java.util.Arrays; class Demo { // I do it this way: static int[] myArray1 = { 1, 2, 3 }; // which is nice and compact. // Some books tell you to do: static int[] myArray2 = new int[] { 1, 2, 3 }; // which works but is more verbose. // Initialize a 2D array in this way: static int[][] twoDimArray = { {1,2,3}, {4,5,6}, {7,8,9} }; public static final void main(String []args) { System.out.println("myArray1=" + Arrays.toString(myArray1)); System.out.println("myArray2=" + Arrays.toString(myArray2)); System.out.println("twoDimArray=" + Arrays.toString(twoDimArray)); } }

Output:

myArray1=[1, 2, 3] myArray2=[1, 2, 3] twoDimArray=[[I@971d0d8, [I@51931956, [I@2b4a2ec7]
