Which statement correctly describes the return statement?

The return statement in Java is used to exit from a method and optionally send a value back to the calling method. The syntax for this statement is indeed return expr;, where expr is an expression that evaluates to a value compatible with the method's return type. This syntax is crucial because it allows the method to return a value, which can be used in the expression that called the method.

In Java, if a method is declared to return a specific data type, using the return statement correctly helps ensure that the method adheres to its contract by providing a value of the expected type. If the method's return type is void, it would simply use the statement return; to exit the method without returning a value.

Understanding the syntax and role of the return statement is essential for effective method design and implementation in Java, enabling programmers to create methods that can communicate results back to their callers accurately.
