Statements

Actions associated with events, transitions, process flowchart objects, agents, controls, etc. in AnyLogic are written in Java code. Java code is composed of statements. A statement is a unit of code, an instruction provided to a computer. Statements are executed sequentially one after another and, generally, in a top-down order. The following code of three statements, for example, declares a variable x, assigns it a random number drawn from a uniform distribution, and prints the value to the model log.

double x;
x = uniform();
traceln( "x = " + x );

You may have noticed that there is a semicolon at the end of each statement. In Java this is a rule:

We will consider these types of Java statements:

• Variable declaration, for example:
  String s; or double x = getX();
• Function call:
  traceln( "Time: " + time() );
• Assignment:
  shipTo = client.address;
• Decisions: if( … ) then { … } else { … }, switch( … ) { case … : … : case : … ; default : … ; }
• Loops: for() { … }, while( … ) { … }, do { … } while( … ) and also break; and continue;
• Blocks: { … }
