Arrays in Java

Unlike C++, arrays are first class objects in Java. For example, in the following program, size of array is accessed using length which is a member of arr[] object.  

Java




// file name: Main.java
public class Main {
    public static void main(String args[]) {
    int arr[] = {10, 20, 30, 40, 50};
    for(int i=0; i < arr.length; i++)
    {
            System.out.print(" " + arr[i]);            
    }
    }
}


Output

 10 20 30 40 50

Time Complexity : O(N) ,where N is size of array
Auxiliary space :O(1)
