81. JK Flip-Flop

How do you plan to solve it?

module jk_ff (
    input  CLK,
    input  J,
    input  K,
    output reg Q
);
always @(posedge CLK)begin
    if(J == 0 && K == 0)
        Q <= Q ;
    else if(J == 0 && K == 1)
        Q <= 0 ;
    else if(J == 1 && K == 0)
        Q <= 1 ;
    else if(J == 1 && K == 1)
        Q <= ~Q ;
    else 
        Q <= Q ;             
end
endmodule
