我正在尝试使用扫描仪和定界符来获取某些文本,但我一直失败。
来自文件的样本:
CROSSPLANE_AXIS = X
DEPTH_AXIS =深度
INPLANE_AXIS_DIR = GUN_TARGET
CROSSPLANE_AXIS_DIR = LEFT_RIGHT
DEPTH_AXIS_DIR = UP_DOWN
能量= 6.00
NOMINAL_DMAX = 13.00
固态硬盘= 1000.00
SCD = 450.00
块= 0
WEDGE = App25x25
public static Double energy;
for (int i = 0; i < lengthOfFiles; i++) {
Scanner readAndStore = new Scanner(content);
int j = 0;
while (readAndStore.hasNextLine()) {
if (readAndStore.hasNext("ENERGY=")) {
readAndStore.useDelimiter("=");
energy = readAndStore.nextDouble();
}
最佳答案
由于您所有的行都是相同的格式,因此更容易
// read all lines
while (readAndStore.hasNextLine()) {
String line = readAndStore.readLine ();
// split using =
String [] words = line.split ("="); // assuming you are going to parse all lines
if (words[0].equals ("ENERGY")) {
energy = Double.parseDouble (words[1]);
}
