Display nodes in the specified structure

[shiniskumar]

Ive got to display node based on the selected level...

Suppose the structure is as follows

A
-> B
->D
->E
->E1
->H
-> C
->F
->G

J
->K
->L
->M
->N
->O

HOW DO I DISPLAY IT IN THIS STRUCTURE WITH THE CORRESPONDING SPACE FOR EACH LEVEL?
I've done it using hashmap...took each node added it to hashmap and then added it to a collection.then its child node added it to hashmap and then to collection and so on...


doing so ive got the tree in the required order of display.
now how do i insert the appropriate space for each node corresponding to each level.?
ie,for level 1 node i,ve to insert 1 space
for level2 nodes i,ve to insert 2 space and so on

Perhaps if you give an example of what you want to do?

ie,,if i choose level 1 i must get the structure as
A
J
if level=2
the structure becomes
A
B
C
J
K
M
if level=3
the structure becomes
A
B
D
H
C
F
J
K
L
M
N

i want to get the logic to include those blank spaces according to the level chosen

now if i select level 3 im getting the output as
A
B
D
H
C
F
J
K
L
M
N

I want this structure as the above displayed one....Hope its clear now

Which blank spaces are you talking about?

Which blank spaces are you talking about?

sorry the blank spaces are not being shown when i submit the form...
Just imagine a tree structure, child coming under parent...
i just need to distinguish the child and its level from the collection i get

Well why din't you try something like

 for(int i = 0; i < level;i++) { 
  System.out.print(" ");
}
 

Prints one space for level one, two spaces for level two, e.t.c
