IO流之创建文件
- 方式1 new File(String pathname)
- 方式2 new File(File parent,String child)//根据父目录文件+子路径构建
- 方式3 new File(String parent,String child)//根据父目录+子路径构建
public class FileCreat {
public static void main(String[] args) {
}
//方式1 new File(String pathname)
@Test
public void creat01() {
String filePath = "d:\\news1.txt";
File file = new File(filePath);
try {
file.createNewFile();
System.out.println("文件创建成功");
} catch (IOException e) {
e.printStackTrace();
}
}
//方式2 new File(File parent,String child)//根据父目录文件+子路径构建
@Test
public void creat02() {
File parentFile = new File("d:\\");
String fileName = "news2.txt";
//这里的file对象,在java程序中,只是一个对象
//只有执行了createNewFile方法,才会真正的在磁盘创建该文件
File file = new File(parentFile,fileName);
try {
file.createNewFile();
System.out.println("news2.txt创建成功");
} catch (IOException e) {
e.printStackTrace();
}
}
//方式3 new File(String parent,String child)//根据父目录+子路径构建
@Test
public void creat03() {
String parentPath = "d:\\";
String fileName = "news3.txt";
File file = new File(parentPath, fileName);
try {
file.createNewFile();
System.out.println("news3.txt创建成功");
} catch (IOException e) {
e.printStackTrace();
}
}
}
