= figure finding node as the workshop applet looks for the specified nodethe prompt will display either going to left child or going to right childand the red arrow will move down one level to the right or left in figure the arrow starts at the root the program compares the key value with the value at the rootwhich is the key is lessso the program knows the desired node must be on the left side of the tree--either the root' left child or one of this child' descendants the left child of the root has the value so the comparison of and will show that the desired node is in the right subtree of the arrow will go to the root of this subtree here is again greater than the nodeso we go to the rightto and then to the leftto this time the comparison shows equals the node' key valueso we've found the node we want the workshop applet doesn' do anything with the node after finding itexcept to display message saying it has been found serious program would perform some operation on the found nodesuch as displaying its contents or changing one of its fields java code for finding node here' the code for the find(routinewhich is method of the tree classpublic node find(int keynode current root/find node with given key /(assumes non-empty tree/start at root
