java - Grouplayout is a bit messed up -
there problem in grouplayout of following code, kindly me figure out
i have uploaded output file, not sure if problem alignment. kingly have , me figure out.

grouplayout constraints-based layout. base principle determine positionning constraints between components, on x , y axis independently.
there 2 constraints : either components in sequence, or in parallel.
in case, layout simple :
- on x axis, there labels in parallel, , textfields in parallel.
- on y axis, there groups of [label , textfield], in parallel
the code following :
