重写循环为单行循环

Question

是否有可能将以下循环重写为单行循环？

for (int i = 0; i < points.length; i++) {
    for (int j = i + 1; j < points.length; j++) {
        if (points[i].equals(points[j])) {
            return "Two vertices coincide therefore a polygon can't be formed";
        }

    }
}
for (int i = 0; i < points.length; i++) {
    for (int j = i + 1; j < points.length; j++) {
        if (points[i].isOnLineSegment(points[j], points[j + 1])) {
            return "There's a vertex on an edge therefore a polygon can't be formed";
        }
    }
}

我想编写发布条件，但除了可能将循环重写为一行之外，我看不到如何做到这一点。

您是否在寻找：

for (int i = 0; i < points.length; i++) {
    for (int j = i + 1; j < points.length; j++) {
        if (points[i].equals(points[j])) {
            return "Two vertices coincide therefore a polygon can't be formed";
        }
        if (points[i].isOnLineSegment(points[j], points[j + 1])) {
            return "There's a vertex on an edge therefore a polygon can't be formed";
        }
    }
}
