Files.lines (Java 8)
如果你是需要按行去处理数据文件的内容，这种方式是我推荐大家去使用的一种方式，代码简洁，使用java 8的Stream流将文件读取与文件处理有机融合。
import java.io.File;
import java.nio.file.Files;
import java.nio.file.Paths;
import java.util.ArrayList;
import java.util.List;
public class readCase {
?? ?public static void main(String[] args) throws Exception {
?? ??? ?readFeatureFiles();
?? ?}
?? ?public static void readFeatureFiles() throws Exception {
?? ??? ?String path="D:\\Project\\Program";? //文件夹路径
?? ??? ?List<String> caseNames =new ArrayList<String>();
?? ??? ?File f = new File(path);
?? ??? ?File[] files = f.listFiles();
?? ??? ?for (int i = 0; i < files.length; i++) {
?? ??? ??? ?System.out.println(files[i].getName());
?? ??? ??? ?String absPath = files[i].getAbsolutePath();
????????????????// 读取文件内容到Stream流中，按行读取
?? ??? ??? ?List<String> lines = Files.readAllLines(Paths.get(absPath));
?? ??? ??? ?
?? ??? ??? ?for (int j = 0; j < lines.size(); j++) {
?? ??? ??? ??? ?String line = lines.get(j);
?? ??? ??? ??? ?if(line.contains("Scenario")) {
?? ??? ??? ??? ??? ?System.out.println(line);
?? ??? ??? ??? ??? ?String caseName = line.substring(line.indexOf(":")+1).trim();
?? ??? ??? ??? ??? ?caseName = caseName.split(" ")[0].trim();
?? ??? ??? ??? ??? ?caseNames.add(caseName);
?? ??? ??? ??? ?}
?? ??? ??? ?}
?? ??? ?}
?? ??? ?for (int i = 0; i < caseNames.size(); i++) {
?? ??? ??? ?System.out.println(caseNames.get(i));
?? ??? ?}
?? ?}
}
