import java.io.File;
public class MainClass {
public static void main(String[] a) throws Exception {
File tmp = File.createTempFile("foo", "tmp");
System.out.println("Your temp file is " + tmp.getCanonicalPath());
}
}
Create temporary file with specified extension suffix
import java.io.File;
//from ww w .j a v a 2 s.co m
public class Main {
public static void main(String[] args) throws Exception {
File file1 = null;
File file2 = null;
file1 = File.createTempFile("JavaTemp", null);
file2 = File.createTempFile("JavaTemp", ".java");
System.out.println(file1.getPath());
System.out.println(file2.getPath());
}
}
Create temporary file in specified directory
/*from w w w .jav a 2 s . com*/
import java.io.File;
public class Main {
public static void main(String[] args) throws Exception {
File file = null;
File dir = new File("C:/");
file = File.createTempFile("JavaTemp", ".javatemp", dir);
System.out.println(file.getPath());
}
}
运行结果如下:
【file_name】
