int[][] as; // this will define an array of arrays of integers
Multidimensional arrays, remember, are simply arrays of arrays. So a two-dimensional array of type int is really an object of type int array (int []), with each element in that array holding a reference to another int array. The second dimension holds the actual int primitives. The following code declares and constructs a two-dimensional array of type int:
int[][] myArray = new int[3][];
Notice that only the first brackets are given a size. That's acceptable in Java, since the JVM needs to know only the size of the object assigned to the variable myArray.

What is the definition of array length in the Java programming language?
When programming in Java language, you will need to use container objects to hold your specific values and these are called Arrays. The amount of values held in these containers is called the Array Length. This is generated once an Array is created and the length becomes locked.

Can ragged arrays created by using java?
I assume you mean that you have a number of rows, and that not all rows have the same number of "cells". Yes, in Java a two-dimensional array is implemented as an array of arrays (each item in the top-level array is, in itself, an array); a 3-dimensional array is an array of arrays of arrays, etc.; and there is no rule stating that all secondary (etc.) arrays must have the same number of elements.

In Java can Array be extended after it has been initialized?
In Java, arrays have a fixed size once they are initialized and cannot be extended. If you need a resizable array, you can use the ArrayList class from the Java Collections Framework, which allows for dynamic resizing. Alternatively, you can create a new array with a larger size and copy the elements from the original array to the new one if you want to extend an existing array.
What is the Java program for sorting an array?
Java has a very efficient built in implementation of quick sort. You can use it on any array of primitives or Comparable Objects by invoking Arrays.sort(<array>) See related link.
