All three methods return a string containing the path information of the file, but they differ from one another. package ĬurrentDirectory = System.getProperty("user. Java File class provides three methods namely getPath, getAbsolutePath and getCanonicalPath.
Java get file path of resource how to#
In this java sample source code we will be illustrating on how to get the current working directory by invoking getProperty() method and passing property name user.dir. Get Current Directory in java using Property user.dir Sample output: Current working directory : C:\Users\ryan\workspace\JavaBasics\. ("Current working directory : "+currentDirectory) * using getAbsolutePath() method of File classĬurrentDirectory = file.getAbsolutePath() * how to get the current working directory This sample java source code demonstrates usage of getAbsolutePath() in getting the current directory. Get Current Directory in java using getAbsolutePath() From this URL you can extract the path by calling toExternalForm(). One other solution is get it using the System.getProperty. Basically getResource method gives the URL. Basically we will explore getAbsolutePath() method of File class under java.lang package. If you look at the code of in Eclipse IDE by using short-cut Ctrl+T and typing this section we will be showing examples on how to get the current directory in java. This means the resource name passed to the method should look like /com/abc/config/app.properties if the app.properties is stored in the package instead of the current class's. Modified_package_name/name where the modified_package_name is the package name of this object with '/' substituted for '.' ('\u002e'). Otherwise, the absolute name is of the following form: If the name begins with a '/' ('\u002f'), then the absolute name of the resource is the portion of the name following the '/'. Since you can pass both absolute and relative paths to Class.getResourceAsStream(), but ClassLoader.getResourceAsStream() takes an absolute path, that's why an absolute resource name is constructed from the given resource name using the following algorithm : We pass the path of the resource to this method but rules for searching resources associated with a given class are implemented by the defining class loader of the class. If you call getResourceAsStream() method on an object which is loaded by BootStrap ClassLoader then it will delegate it to ClassLoader.getSystemResourceAsStream() method. Internally this method delegates the loading request of resource to its class loader. If you are creating J2ME games or applications, you can use these methods to load icons and tiles for your game, and all other resources for your application as well.
These methods are available from JDK 1.1 and you can even use them anywhere you have access to the core Java library. class with the name of any class like Sample.class will give you a reference of. If you have an object, then you can call getClass() because it's a non-static method, on the other hand, if you don't have an object, you can simply use. You can obtain a reference of Class by calling either getClass() method or by using class literal.
These methods accept the path of resource as String and return URL and InputStream respectively. Suppose, you have a properties file inside the config folder of your project, and you want to load that properties file, how do you do that? Similarly, you have icons and thumbnails for your web applications on the icons directory of your project, how do you load them? The answer is by using ' getResource() and getResourceAsStream() method.
Java provides API to read these resources as InputStream or URL. properties files, images, icons, thumbnails, or any binary content. class files, but also can be used to load resources e.g. Classpath in Java is not only used to load.
