在Kotlin中,可以使用ByteArrayInputStream类将字符串转换为InputStream。下面是一个示例代码: 代码语言:txt 复制 fun stringToInputStream(str: String): InputStream { val bytes = str.toByteArray() return ByteArrayInputStream(bytes) } 在这个示例中,我们首先使用toByteArray()函数将字符串转换为字节数组...
依赖Java版本没有错，但在可能的情况下使用更多的kotlin惯用法
fun readDictionary(file: File): Map<String, *> =file.inputStream().use { TODO("Read a mapping of strings to arbitrary elements.") }//我们已将存有一些 `Int` 的映射保存到该文件val intsFile = File("ints.dictionary")//Warning: Unchecked cast: `Map<String, *>` to `Map<String, Int...

def output = p.inputStream.text 1. 2. 在Kotlin 中,目前还没有对 String 类和 Process 扩展这样的函数。其实扩展这样的函数非常简单。我们完全可以自己扩展。 首先,我们来扩展 String 的 execute() 函数。 fun String.execute(): Process { val runtime = Runtime.getRuntime() ...

首先通过File对象获取InputStream实例,通过inputStream获取bufferedReader,最后通过bufferedReader.use高级函数读取文件内容,并返回String 如果需要逐行读取,则需要以下方式: val inputStream:InputStream=File("kotlin.txt").inputStream() val lineList=mutableListOf() ...
