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)
