I need the code for this exercise in Java.

In an educational institute there are several registered students of each of them, their full name, age and whether they are in primary or secondary school . In addition, a static attribute must be created to count the number of students entering the school.

6 numbers of students must be created through the use of arrayList.

Override the toString method to display only the student's name and age Display on screen the name and age of all students in descending format (from oldest to youngest) depending on their age. At the time of loading the age, it must be validated by the use of checked or unchecked exceptions. Thanks
