Given the following java code snippet , write detailled UML diagram that converts the parrell array into a data definition class (DDC) called country

String[] countries = {"USA", "CHINA", "JAPAN"}

int[] callingCodes= {1.86,81};

Question 2What will be the result of excuting the following code? Assume that Foo has anb empty argunment constructor

Foo[] arr = new Foo[1];

arr[1] = new Foo();

question 3What will add a student object to the student array called classRoom in the second place of array

student [] classRoom = new Student [10];

question 4 given the partial UML diagram below for the ClassRoom DDC, write in Java, a mutator to add a student name to the studentNames instance variable array

Make sure you perform the appropriate validation

(+)MAX_Enrolled_Students : int

(-) noOfEnrolled =Students: int

(-)studentNames: String[]
