Write and test a Java method clshift() that takes array of integers and performs a circular left shift on the array, and then prints its elements

public class Main
{
	public static void main(String[] args) {
	    int a[]={3,5,1,2,45};

	  clshift(a);      
	    }
	
	public static void clshift(int []a)
	{
	   /* shifting array elements */
     int temp=a[0];
     for(int i=0;i<a.length-1;i++)
     {
       a[i]=a[i+1];
     }
     a[a.length-1]=temp;
 
     System.out.println("\nNew array after rotating by one postion in the left direction");
     for(int i=0;i<a.length;i++)
     {
       System.out.print(a[i]+" ");
     }

	}
}
