Get an Absolute Filename Path from a Relative Filename with Path in Java
The method java.io.File.getAbsoluteFile() can be used to acquire the absolute filename path from a relative filename with path in Java. This method requires no parameters. It returns the file that is defined by the path name.
A program that demonstrates this is given as follows −
Example
import java.io.File;
public class Demo {
public static void main(String[] argv) throws Exception {
File file = new File("c:" + File.separator + "JavaProgram" + File.separator + "demo1.txt");
file = file.getAbsoluteFile();
System.out.println(file);
}
}The output of the above program is as follows −
Output
c:\JavaProgram\demo1.txt
Now let us understand the above program.
The method java.io.File.getAbsoluteFile() is used to acquire the absolute filename path from a relative filename with path. Then this is printed. A code snippet that demonstrates this is given as follows −
