If you are new in Java programming then our tutorials and examples will be helpful in understanding Java programming in the most simplest way. Here after reading this lesson, you will be able to find the absolute path of a file or directory.
To find a file or directory it is very necessary to know the path of the file or directory so that you can access it. If you know the path then it is very easy to work on it. Suppose a situation where a problem comes in front you where you don't know the path of the file, then what will you do. Then this problem can be solved by using a method getAbsolutePath(). The method getAbsolutePath() should be used where we don't know the exact path of the file.
To find an absolute path of a file, Firstly we have to
make a class GetAbsolutePath. Inside this class define the main method.
Inside this method define a File class of java.io package. Inside the
constructor of a File class pass the name of the file whose absolute path you
want to know. Now call the method getAbsolutePath() of the File class
by the reference of File class and store it in a String variable.
Now print the string, you will get a absolute path of the file.
In this class we have make use of the following things by which this problem can be solved.
File: It is class in java.io package. It implements Comparable and Serializable interface.
getAbsolutePath(): It returns the absolute path name in the form of string.
Code of the program is given below:
Output of the program is given below.
The absolute path in first form is C:\java\java
The absolute path is C:\java\java\java
The absolute path is C:\java\java\..\java
