Java.util.ResourceBundle.getStringArray() Method
Description
The java.util.ResourceBundle.getStringArray(String key) method gets a string array for the given key from this resource bundle or one of its parents.
Declaration
Following is the declaration for java.util.ResourceBundle.getStringArray() method
public final String[] getStringArray(String key)
Parameters
key − the key for the desired string array
Return Value
This method returns the string for the given key array
Exception
NullPointerException − if key is null
MissingResourceException − if no object for the given key can be found
ClassCastException − if the object found for the given key is not a string
Example
The following example shows the usage of java.util.ResourceBundle.getStringArray() method.
package com.tutorialspoint; import java.util.ArrayList; import java.util.Enumeration; import java.util.Locale; import java.util.ResourceBundle; // this method seems to be having problems with the base implementation // the following example shows an alternative way doing the same function public class ResourceBundleDemo { public static String[] getPropertyStringArray(ResourceBundle bundle, Strin keyPrefix) { String[] result; Enumeration<String> keys = bundle.getKeys(); ArrayList<String> temp = new ArrayList<String>(); // get the keys and add them in a temporary ArrayList for (Enumeration<String> e = keys; keys.hasMoreElements();) { String key = e.nextElement(); if (key.startsWith(keyPrefix)) { temp.add(key); } } // create a string array based on the size of temporary ArrayList result = new String[temp.size()]; // store the bundle Strings in the StringArray for (int i = 0; i < temp.size(); i++) { result[i] = bundle.getString(temp.get(i)); } return result; } public static void main(String[] args) { // create a new ResourceBundle with specified locale ResourceBundle bundle = ResourceBundle.getBundle("hello", Locale.US); // save the keys in a string array String[] s = ResourceBundleDemo.getPropertyStringArray(bundle, ""); // print the string array one by one for (int i = 0; i < s.length; i++) { System.out.println("" + s[i]); } } }
Assuming we have a resource file hello_en_US.properties available in your CLASSPATH, with the following content. This file will be used as an input for our example program −
hello = Hello World! bye = Goodbye World! morning = Good Morning World!
Let us compile and run the above program, this will produce the following result −
Hello World! Goodbye World! Good Morning World!
