Java nested for while loops

I am having troubles with nested while loops in a for loop. I understand the nested for loop:

    for (int i = 0; i<5;i++)
    {
        for (int j=i;j<5;j++)    
        {
           System.out.print("*"); 
        }
        System.out.println();
    }

When it comes to a while loop inside a for loop I'm kinda lost, can someone explain it to me?

Expected output:
*****
****
***
**
*
