PowerBuilder permits the use of the first two comment styles, while the third is new to Java.

The choice of comment style depends on the size and nature of the comment. In Java, white space (spaces, tabs, carriage returns and line feeds) is ignored except for within strings and no line continuation characters are required.Д¬omments In Java there's a choice of three comment styles to choose from: single-line, multiline or the documentation comment. PowerBuilder is not case sensitive except for embedded SQL statements. Java is also a case-sensitive language, and differentiates between the keywords 'hello' and 'Hello'. You use the carriage return as a statement separator and reserve the use of the semicolon to end embedded SQL statements. You don't usually use a semicolon to end a single statement. In PowerBuilder, however, embedded SQL statements must end with the semicolon. In PowerBuilder, statements can end with either the carriage return or the semicolon. In Java, all statements must end with the semicolon, ' '. Both the Java and PowerScript programming languages contain these building blocks. You use these building blocks to build dynamic applications. The Java Language All programming languages contain fundamental building blocks such as variables, control statements, operators and methods. Java on the other hand doesn't hide any details from you other than the implementation of the core libraries. PowerBuilder does an excellent job of hiding from you the low-level details required to assemble objects at runtime. Essentially, both Java and PowerBuilder represent their programs as a collection of objects that communicate and interact with one another.
