This method ensures that the file is closed when all bytes have been read or an I/O error, or other runtime exception, is thrown. After reading all the bytes, we pass those bytes toStringclass constructor to create a new String. Reading file to byte array PathfilePath=Path.of("c:/tem...

你可以使用Java中的FileInputStream类来读取文件内容到byte数组。 下面是一个示例代码: import java.io.File; import java.io.FileInputStream; import java.io.IOException; public class ReadFileToByteArray { public static void main(String[] args) { File file = new File("path/to/file"); // 替换...
List的toArray()方法主要有两个重载版本:一个不带参数,一个带一个数组作为参数。不带参数的toArray()方法默认将List转换为Object[]数组。而带一个数组作为参数的toArray()方法可以将List转换为指定类型的数组。例如,如果我们有一个String类型的List,我们可以使用以下代码将其转换为String[]数组: List<String> list...
