如何编写一个程序来用Java将字符从一个文件复制到另一个文件？
将一个文件的内容逐字符复制到另一字符
示例
import java.io.File;
import java.io.FileInputStream;
import java.io.FileOutputStream;
import java.io.IOException;
public class CopyFiles {
public static void main(String[] args) throws IOException {
//创建一个File对象来保存源文件
File source = new File("D:\\ExampleDirectory\\SampleFile.txt");
//创建一个File对象来保存目标文件
File destination = new File("D:\\ExampleDirectory\\outputFile.txt");
//创建一个FileInputStream对象
FileInputStream inputStream = new FileInputStream(source);
//创建一个FileOutputStream对象
FileOutputStream outputStream = new FileOutputStream(destination);
//创建一个缓冲区来保存数据
int length = (int) source.length();
byte[] buffer = new byte[length];
while ((length = inputStream.read(buffer)) > 0) {
outputStream.write(buffer, 0, length);
}
inputStream.close();
outputStream.close();
System.out.println("File copied successfully.......");
}
}输出结果
File copied successfully.......
