Write me a code in the java langauge with the only instance variable being:

'private char$[][]$ grid;$\text{'}$

above the top row.

public boolean remove$($Line theLine$)$

Returns false if theLine is not a valid line, i$.$e$.$ if the line's start or end points are

not within the grid. For example, if grid has $3$ rows and $4$ columns, theLine starts

at row $1,$ column $1$ and it ends at row $1,$ column $5$ then method remove must

return false as part of theLine is not within the array grid. Recall that in a two$-$

dimensional array the first row has index $0$ and the first column also has index $0.$

If theLine is valid, this method replaces with EMPTY the entries in grid

corresponding to theLine. And then it returns true. For example, if grid has $3$ rows

and $4$ columns and theLine starts at row $1,$ column $1,$ and it ends at row $1,$

column $2,$ then the entries of grid in row $1,$ columns $1$ and $2$ are replaced with

EMPTY and the method returns true.
