Which of the following are valid Java identifiers? (Choose all that apply)
✅ A. A$B ✅ B. _helloWorld ❌ C. true ❌ D. java.lang ✅ E. Public ❌ F. 1980_s
Explanation: Option A is valid because you can use the dollar sign in identifiers. Option B is valid because you can use an underscore in identifiers. Option C is not a valid identifier because true is a Java reserved word. Option D is not valid because the dot (.) is not allowed in identifiers. Option E is valid because Java is case sensitive, so Public is not a reserved word and therefore a valid identifier. Option F is not valid because the first character is not a letter, $, or _.
