描述

Each variable declaration must be in its own statement

提示语句

float r = (float) 1 / len, s = (len + 1) * r;

    /**
     * 获取透明度,从0到1,自动计算步长
     *
     * @return float 透明度
     */
    private float getAlpha(int i, int j) {
        int num = i + j;
        float r = (float) 1 / len, s = (len + 1) * r;
        return num > len ? (num * r - s) : num * r;
    }
