Notice that snippet #7 has been removed, and a snippet #15 has been added thanks to the /12 command. Finally, we entered /list to re-list all snippets. Next, we entered /drop 7 to delete snippet #7 (no more age += 10 snippet). We then entered /list 13 to list snippet #13, which increments age. Here we've entered /12 to re-execute snippet #12, which outputs the contents of text. A compound statement is a sequence of simple and other compound statements located between open- and close-brace characters (.A simple statement is a single standalone instruction for performing a task it must be terminated with a semicolon character ( ).A statement can be expressed as a simple or a compound statement: Java applications evaluate expressions in the context of statements, which are used for tasks such as declaring a variable, making a decision, or iterating over statements.
