Thread: Need help with understanding arrays

If I had a string array such as array[1]="abcd". Is it possible to interate through the elements of that, so for example if I wanted to shift the positions to make it dabc. So far I only have come across problems where an array, for examples args who has 3 elements args[0]=1, args[1]=2 and args[2]=3 and I would use a FOR loop to do that:

int b=3;
String[] args= new char[b];
 
for(int i=0; i < args.length; i++)
{
   //do something
}

Pretty much what I'm wondering is, can you iterate through a string in one element of an array using a loop?

Hi I tried to just make a sample code for me to understand how to change the elements to containing a different letter but it didn't quite work out. I am trying to shift 1 position down, so b to the first element, c to second element and etc. I was thinking of using a nested for loop but then I got even more confused.

 String test="abcd";
 char[] array = test.toCharArray();
 
                 for(int i=1; i < array.length; i++)
		 {
			 array[i]=array[i-1];
		 }
 
		         System.out.print(array[0]);
		         System.out.print(array[1]);
		         System.out.print(array[2]);
		         System.out.print(array[3]);

Ah nevermind. I think I have got the hang of it.
