About BorderLayout and its Named Children

The borderLayout component is a layout element that arranges its indexed children in the middle of a container, and supports the following named children, which arrange their child components in predefined, named areas:

bottom - Lays out children at the bottom of the container, below the indexed children.
end - Lays out children in the same area as defined by right. If the reading direction is from right to left, lays out children in the same area as defined by left.
innerBottom - Lays out children below the indexed children and above bottom children.
innerEnd - Lays out children in the same area as defined by innerRight. If the reading direction is from right to left, lays out children in the same area as defined by innerLeft .
innerLeft - Lays out children between the left of indexed children and the right of left children, and in between top and bottom children.
innerRight -Lays out children between the right of indexed children and the left of right children, and in between top and bottom children.
innerStart - Lays out children in the same area as defined by innerLeft. If the reading direction is from right to left, lays out children in the same area as defined by innerRight.
innerTop - Lays out children above the indexed children and below top children.
left - Lays out children to the left of the indexed children and in between top and bottom children.
right - Lays out children to the right of the indexed children and in between top and bottom children.
start - Lays out children in the same area as defined by left. If the reading direction is from right to left, lays out children in the same area as defined by right.
top - Lays out children at the top of the container, above the indexed children.

Notes:

Each borderLayout named child (or named area) can contain any number of child components.
If the reading direction is from left to right, right has precedence over end when both end and right are used. Similarly, left has precedence over start when both start and left are used. The same is true for innerEnd and innerRight , and innerStart and innerLeft.

Indexed children in the middle are arranged consecutively, in the order in which they are listed.
