A primitive variable type is predefined by the language and is named by a reserved keyword. There are eight primitive data types supported by the Java programming language. Sun, 20 Aug 2017 15:05:00 GMT http://bucarotechelp.com/program/java/81041702.asp A Java boolean can have one of two values: true or false. In some languages, such as C or C++, integer values can be treated as a boolean, with 0 equal to false and any other value equal to true. Not so in Java. In Java, you can't convert between an integer type and a boolean type. Mon, 14 Aug 2017 15:28:52 GMT http://bucarotechelp.com/program/java/81041802.asp In Java information that can be changed as the program runs is stored in variables.
