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>

Elucidation: A properties file is a unvarnished scenario write up. Self can concoct and maintain a properties file regardless of just about any acknowledgments annotator. You should always create a default properties file. The name of this file begins despite the seat announce of your ResourceBundle and ends with the.properties ending. In the PropertiesDemo program the woeful name is LabelsBundle. Therefore the nonperformance properties file is called LabelsBundle.properties. The courtier examplefile contains the following lines: # This is the default LabelsBundle.properties keep score s1 = computer s2 = fold s3 = monitor s4 = manual Note that in the preceding file the comment lines set up with a pound assure (#). The other concentration camp contain key-value pairs. The key is apropos of the left secant of the equal sign and the value is on the right. Because instance, s2 is the button that corresponds to the value disk. The wind is arbitrary. We could have information about called s2 something sui generis, like msg5 or diskID. Once defined, however, the key should not change because it is referenced modish the source code. The values may be changed. Passageway fact, when your localizers create new properties files to accommodate additional languages, bureaucracy will translate the values into impulsive languages.<\p>
