Need help with the following questions.

You must define/describe/explain the following questions (50%) and include a sample Java code (50%). 1. Object-oriented programming ultimately requires a solid understanding of 7 terms. (explain object, attribute, method, class, encapsulation, inheritance, and polymorphism. Each one also needs a sample Java code) 2. String concatenation (t). (outputs of 3 codes) 3. In Java, conversions can occur in 3 ways. (assignment conversion, promotion, and casting. Each one also needs a sample Java code) 4. There are two kinds of Java programs. (Java applets and Java. Each one also needs a sample Java code) 5. Primary data type and object data type. (in terms of data declaration, assignment, and aliases. Each one also needs a sample Java code) 6. Static methods. (define and invoke. Each one also needs a sample Java code) 7. NumberFormat class, getCurrencylnstance and getPercentlnstance in NumberFormat class. (Each one also needs a sample Java code) 8. Enumerated type. (define, declare, invoke. Each one also needs a sample Java code) 9. Wrapper classes. (define, explain. Each one also needs a sample Java code) 10. Autoboxing. (define, explain. Each one also needs a sample Java code) 11. Java visibility modifiers. (private, public, and protected. Each one also needs a sample Java code) 12. Java visibility modifiers. (violate encapsulation.
