Given: public enum USCurrency { PENNY (1), NICKLE(5), DIME (10), QUARTER(25); private int value; public USCurrency(int value) { this.value = value; }…

There are two compilation errors in the provided code. First, enum constructors cannot be declared public or protected; they are implicitly private. The public modifier on the USCurrency constructor must be removed or changed to private. Second, enum constants are static, final instances and are not created using the new keyword. The line new USCurrency.DIME is incorrect syntax for accessing an enum constant. It must be changed to USCurrency.DIME. Therefore, making the constructor private and removing the new keyword will allow the code to compile.

A. Nesting the enum is a stylistic choice and is not required for the code to compile. A top-level enum is perfectly valid.
D. The getValue() method is an instance method that correctly retrieves the value for a specific enum constant (e.g., DIME). Making it static would be incorrect.
E. While making the value field final is good practice, it is not required for the code to compile.
