[1.1] JAVA: Please explain reference semantics in comparison with value semantics (2 pts) using examples of both value semantics and reference semantics with the methods called [1.2] swap()(2 pts) which takes two integer values, and [1.3] reverse()(2 pts) which takes an array of integers. [1.4] What are the advantages of reference semantics over value semantics? (2 pts), (total 8 pts)

Answer for the [1.1] and [1.4] should be included in the program with both methods as the comment.

[1.1] Reference semantics in comparison with value semantics: (2 pts)

[1.4] The advantages of reference semantics over value semantics: (2 pts)

[1.2] swap() method (2 pts)

public static void swap(int n1, int n2) {

}

[1.3] reverse () method (2 pts)

public static void reverse(int[] numbers) {

}
