1、创建文件对象相关构造器和方法
new File(String pathname) //根据路径构建一个 File 对象
new File(File parent,String child) //根据父目录文件+子路径构建
new File(String parent,String child) //根据父目录+子路径构建
createNewFile() //创建文件
import org.testng.annotations.Test;
import java.io.File;
import java.io.IOException;
public class FileCreate {public static void main(String[] args) {
}
//方式 1
@Test
public void create1(){
String filePath = "D:\\file1.txt";
File file = new File(filePath);
try {
file.createNewFile();
System.out.println("创建文件 1 成功");
} catch (IOException e) {
e.printStackTrace();
}
}
//方式 2
@Test
public void create2(){
File parentFile = new File("D:\\");
String fileNane = "file2.txt";File file = new File(parentFile, fileNane);
try {
file.createNewFile();
System.out.println("文件 2 创建成功");
} catch (IOException e) {
throw new RuntimeException(e);
}
}
//方式三
@Test
public void create3(){
String parentPath = "d:\\";
String filePath = "file3.txt";
File file = new File(parentPath, filePath);
try {
file.createNewFile();
System.out.println("文件 3 创建成功");} catch (IOException e) {
throw new RuntimeException(e);
}
}
}
