Java Source Code Recursion

Java Source Code Recursion
Below is the free java source code of a recursive Koch Snow Flakes. Have fun with it by trying it in your java compiler and also I suggest that you study its algorithm and make other java applet applications using it as a reference. This recursive koch snow flakes program use the recursive Serpienski Gasket as its main reference as well as used the formula below in forming its source code.

Java Source Code: Recursive Koch Snow Flakes Formula:
Given the 2 Points (X1, Y1) and (X5, Y5)

this Java Source Code Recursion:
Here are the Snapshots for the Sample Output of this Program.
Enter the depth of recursion: 0 


 ------Let------  
 deltaX = X5 - X1,  
 deltaY = Y5 - Y1  
 X2 = x1 + deltaX / 3,  
 Y2 = Y1 + deltaY / 3  
 X3 = 0.5 * (X1 + X5) + squareRootOf(3) * (Y1 - Y5) / 6,  
 Y3 = 0.5 * (Y1 + Y5) + squareRootOf(3) * (X5 - X1) / 6  
 X4= X1 + 2 * deltaX / 3,  
 Y4 = Y1 + 2 * deltaY / 3
