Utils to read resource text file to String (Java) [closed]

Answer 1

Yes, Guava provides this in the Resources class. For example:

URL url = Resources.getResource("foo.txt");
String text = Resources.toString(url, StandardCharsets.UTF_8);

Answer 2

yegor256 has found a nice solution using Apache Commons IO:

import org.apache.commons.io.IOUtils;

String text = IOUtils.toString(this.getClass().getResourceAsStream("foo.xml"),
                               "UTF-8");

Answer 3

With set of static imports, Guava solution can be very compact one-liner:

toString(getResource("foo.txt"), UTF_8);

The following imports are required:

import static com.google.common.io.Resources.getResource
import static com.google.common.io.Resources.toString
import static java.nio.charset.StandardCharsets.UTF_8

Answer 4

You can use the following code form Java

new String(Files.readAllBytes(Paths.get(getClass().getResource("example.txt").toURI())));

Answer 5

You can use the old Stupid Scanner trick oneliner to do that without any additional dependency like guava:

String text = new Scanner(AppropriateClass.class.getResourceAsStream("foo.txt"), "UTF-8").useDelimiter("\\A").next();

Guys, don't use 3rd party stuff unless you really need that. There is a lot of functionality in the JDK already.

Answer 6

If you want to get your String from a project resource like the file testcase/foo.json in src/main/resources in your project, do this:

String myString= 
 new String(Files.readAllBytes(Paths.get(getClass().getClassLoader().getResource("testcase/foo.json").toURI())));

Note that the getClassLoader() method is missing on some of the other examples.
