An invocation of a method that returns a value can be used as an expression any place that a value of the Type_Returned can be used.

An invocation of a method that returns a value can be used as an expression anywhere that a value of the Type_Returned can be used. This follows from the definition of a method, which is a block of statements that performs a specific task and returns a value to the caller. The value returned by a method can be assigned to a variable, used in an expression, or passed as an argument to another method. Therefore, a method invocation that returns a value is an expression, and can be used as such.
