DataInputStream.readDouble介绍

[英]See the general contract of the readDouble method of DataInput.

Bytes for this operation are read from the contained input stream.
[中]参见readDouble方法DataInput的总合同。
此操作的字节从包含的输入流中读取。

代码示例

DataInputStream in = new DataInputStream(new BufferedInputStream(
             new FileInputStream("filename")));
int x = in.readInt();
double y = in.readDouble();

etc.

  double lowerLeftLatitude = stream.readDouble();
  double lowerLeftLongitude = stream.readDouble();
  if (lowerLeftLongitude > 180) {
    lowerLeftLongitude -= 360; //convert to standard coordinates
  }
  double deltaLatitude = stream.readDouble();
  double deltaLongitude = stream.readDouble();
  int nRows = stream.readInt();
  int nColumns = stream.readInt();
  float[][] data = new float[nRows][nColumns];
  for (int y = 0; y < nRows; ++y) {
    for (int x = 0; x < nColumns; ++x) {
      data[y][x] = stream.readFloat();
    }
  }
  return new VerticalDatum(lowerLeftLongitude, lowerLeftLatitude, deltaLatitude * nColumns, deltaLongitude * nRows, data);
}
