这个方法接受一个字符串参数,并返回一个Path对象表示这个路径。 下面是一个简单的示例代码,演示了如何将字符串转换为路径: importjava.nio.file.Path;importjava.nio.file.Paths;publicclassStringToPathExample{publicstaticvoidmain(String[]args){Stringstr="/Users/username/Documents/test.txt";Pathpath=Paths.get...
例如：Path path = Paths.get("data.txt"); try (Stream<String> stream = Files.lines(path)) {...
finalPath path =newFile("E:\\software\\idea-注册码.txt").toPath();try(java.util.stream.Stream<String> lines =Files.lines(path, StandardCharsets.UTF_8)){ lines.onClose(()-> System.out.println("done")).forEach(System.out::println); }catch(Exception e){ e.printStackTrace(); } 对...
finalPath path =newFile( filename ).toPath();try( Stream< String > lines =Files.lines( path, StandardCharsets.UTF_8 ) ) { lines.onClose( ()-> System.out.println("Done!") ).forEach( System.out::println ); } Stream的方法onClose()返回一个等价的有额外句柄的Stream,当Stream的close(...
[5, 6],String 转变成了 Integer [欢迎, 阅读, 鳄鱼儿, 文章],一个流中的每个值都转换为另一个流,最好组合成一个新的stream。 mapToInt、mapToLong、mapToDouble分别是返回一个IntStream、LongStream、DoubleStream。 这些类型的stream包括一些sum()、max()min()方法等,可以用于计算,如下面代码求和示例: ...
