- An array without name is known as anonymous array in java.
- As the array do not have any name so it can be used only once.
- Anonymous array is passed as an argument of method.
- Anonymous array is created and initialized in the same line.
How to Create Anonymous Array in Java?
A sample program is given below which shows that how 1D and 2D anonymous array can be created and used in java. In this program I have just created, initialized and passed two anonymous arrays in a method. In print() method I am printing the elements of the arrays. If you find any difficulty to understand the program then you can comment below and ask your queries.

class AnonymousArray { static void print(int a[]) { for(int i=0;i<a.length;++i) System.out.print(a[i]+" "); } static void print(int a[][]) { for(int i=0;i<a.length;++i) { for(int j=0;j<a[i].length;++j) System.out.print(a[i][j]+" "); System.out.println(""); } } public static void main(String...s) { //1d anonymous array print(new int[]{10,20,30,40}); System.out.println("n"); //2d anonymous array print(new int[][]{{10,20},{30,40},{50,60}}); } } |
Thank you sir this is nice tutorial. My concept is now totaly clear….
why we are using “new” in the main class of the print
