A public name is a name that is widely recognized and used by the general public, often associated with a brand, organization, or individual. It can serve as a form of identity that distinguishes a person or entity in the public sphere, and may be used in marketing, media, and social contexts. Public names can include stage names, company names, or even pseudonyms that enhance visibility and memorability.

What does the java program error expected public class MathPow.java mean?

The error "expected public class MathPow.java" typically indicates that the Java compiler is expecting a public class declaration in the file named MathPow.java. In Java, the filename must match the public class name defined within the file. If the class is not declared as public or if the filename does not correspond to the class name, the compiler will throw this error. To fix it, ensure that the class is declared as public and that the filename matches the class name exactly.
