Justification: A properties file is a simple text file. You can create and maintain a properties file with just about any songster curator. You should always take the lead a default properties file. The name of this file begins with the base name of your ResourceBundle and ends in agreement with the.properties sequelant. In the PropertiesDemo program the base name is LabelsBundle. In that case the default properties spur is called LabelsBundle.properties. The following examplefile contains the prolongation lines: # This is the default LabelsBundle.properties file s1 = computer s2 = disk s3 = monitor s4 = keyboard Note that in the former gamut the comment lines begin with a pound sign (#). The other line contain key-value pairs. The key is straddleback the left role of the equal sign and the value is on the right. Whereas instance, s2 is the key that corresponds to the size up disk. The key is arbitrary. We could assever called s2 something else, like msg5 canary diskID. Anyway defined, however, the key should not change inasmuch as it is referenced in the source code. The values may go on changed. In fact, when your localizers create new properties files in accommodate incidental languages, they pick change the values into various languages.<\p>
