What are Functions in Java ...?

Question

Functions

Answer 1

They are blocks of code that can be called repeatedly. They can have parameters and return something. Read it in more detail in the course

Answer 2

Martin Taylor quite nitpicky but correct 🙄😉
SE8 introduced java.util.function however, but i don't think he meant that

Answer 3

Method and a function are the same, with different terms. A method is a procedure or function in object-oriented programming. A function is a group of reusable code which can be called anywhere in your program. This eliminates the need for writing the same code again and again.
