I have written a public instance method moveBy() whose first argument is an int representing the distance to move and whose second argument is a char representing the direction in which to move. It should return no value.

Table 1: Directions and corresponding x and y increments

 Direction xInc yInc (this is not a code) Right 'R' 1 0 Left 'L' -1 0 Up 'U' 0 -1 Down 'D' 0 1 

I need to begin by declaring local int variables xInc and yInc and use the table above to set these for the appropriate increments depending on the supplied argument for direction.

This is what I have done so far: please if someone can correct me and help me! many thanks

public void moveBy(int distance, char direction) { int xInc = 0; int yInc = 0; }

or I tried this for the first bit but it says' identifier expected'.

int xInc = 1,-1, 0, 0 int yInc = 0, 0, -1, 1
