❌ A. -1 ✅ B. 9 ❌ C. 81 ❌ D. Compiler error on line 9. ❌ E. Compiler error on a different line
Explanation: Since Java is pass-by-value and the variable on line 8 never gets reassigned, it stays as 9. In the method square, x starts as 9. y becomes 81 and then x gets set to –1. Line 9 does set result to 81. However, we are printing out value and that is still 9.
