in java, please do this recursively..

only the code for the recursive, dont worry about the turtle package..

using the turtle package in javaZ

2. Create a recursive function tree (length, n) that takes the length of the trunk and the number of branches as parameters and recursively draws n. branches where the leftmost and rightmost branches are a total of 120 degrees apart. The length of each recursive branch should be half the length of the parent. Branches must be at least 5 pixels long. Test your function by drawing at least two trees with different numbers of branches: tree (100, 3) tree (100, 4) tree(100, 6): Wint. For a hinar recursive tree example, see
