Java 我有坐标表，我的要求是安排它,java,geometry,drawing,coordinates,Java,Geometry,Drawing,Coordinates,我有一张坐标表要画线 事实上，问题是这些坐标不是按顺序排列的 终点线坐标是另一条线的终点线坐标。 如果任何一条线的端点坐标与另一条线的起点坐标不匹配，则创建连接线列表 线的坐标为startx、starty、endx、endy 下面是直线坐标列表 3350 1500 3200 1500 1450 1750 1450 2200 1450 2200 2100 2200 2400220025502200 2550220025502350 2550235028502350 2850 2350 2850 2

我有一张坐标表要画线

事实上，问题是这些坐标不是按顺序排列的

终点线坐标是另一条线的终点线坐标。 如果任何一条线的端点坐标与另一条线的起点坐标不匹配，则创建连接线列表

线的坐标为startx、starty、endx、endy

下面是直线坐标列表

3350 1500 3200 1500

1450 1750 1450 2200

1450 2200 2100 2200

2400220025502200

2550220025502350

2550235028502350

2850 2350 2850 2700

2850270033502700

3650270037502700

3750270037502600

3750260052502600

5250 2600 5250 2350

5250 2350 5000 2350

4700 2350 4350 2350

4350235043501600

4350 1600 3650 1600

3650 1600 3650 1500

3200150032001750

3200 1750 1450 1750

最后两条线的坐标实际上位于第二和第三位置

3200150032001750

3200 1750 1450 1750

我的要求是创建所有相互连接的线束

List<DeviceElement> outerListWire= new ArrayList<DeviceElement>(schematicImporter.listOfWires);
List<DeviceElement> innerListWire = new ArrayList<DeviceElement>(schematicImporter.listOfWires);
    List<DeviceElement> listWireTemp = new ArrayList<DeviceElement>();
for (int j = 0; j < outerListWire.size(); j++) {
    Wire wire1 = (Wire) outerListWire.get(j);
    for (int i = 0; i < innerListWire.size(); i++) {
        Wire wire2 = (Wire) innerListWire.get(i);

        if (wire1.getEndPoint().getX() == wire2.getStartPoint().getX() && wire1.getEndPoint().getY() == wire2.getStartPoint().getY() ) {
            if (!listWireTemp.contains(wire1)) {
                listWireTemp.add(wire1);
                System.out
                .println("wire1 = " + wire1.getStartPoint().toString() + " = " + wire1.getEndPoint().toString());
                innerListWire.remove(wire1);
            }

            if (!listWireTemp.contains(wire2)) {
                listWireTemp.add(wire2);
                System.out
                .println("wire2 = " + wire2.getStartPoint().toString() + " = " + wire2.getEndPoint().toString());
                innerListWire.remove(wire2);
            }
        }
    }
}

List outerListWire=new ArrayList（schematicporter.listofwire）；
List innerListWire=新的ArrayList（schematicImporter.listOfWires）；
List listWireTemp=new ArrayList（）；
对于（int j=0；j
我已经尝试了上面的代码，但坐标列表仍然没有按顺序排列。

根据以下假设进行了更新：

[Line [x1=3350, y1=1500, x2=3200, y2=1500], Line [x1=3200, y1=1500, x2=3200, y2=1750], Line [x1=3200, y1=1750, x2=1450, y2=1750], Line [x1=1450, y1=1750, x2=1450, y2=2200], Line [x1=1450, y1=2200, x2=2100, y2=2200]]

  • 问题中给出的第一行坐标表示连接线集中第一行的坐标
  • 在找到第一组连接线后，问题中给出的剩余坐标线的第一条未使用的线将被视为下一组连接线中第一条线的坐标，依此类推，直到问题中给出的坐标列表消失

    您好，您能举例说明一下每行的坐标是如何表示的吗？@mettleap我有一个更新问题。请查收。@ArvindKumarAvinash，我本想说同样的话…@BhavinS。ew是否可以假定第一行上的坐标是起点？是的，每次此代码仅给出连接线的第一个列表时，第一行上的坐标都是起点。目标是找到所有连接的线路。
