How can I store large data in arrays?? Like I am writing a code for student grades management how can I store info(name, id, age, grades, course enrolled) of student in array list?

Basically you need to create the student object and then you add that object with all the attributes to your list like List<Student> students = new ArrayList(); students.add(student1); If you need to handle many records, reading the students from a file or a database would be the better solution than creating them one by one.

Class Students { private String name; Private int age; private String grade; public Students (String name,int age, String grade){; this.age=age; this.grade=grade; } //get and setters. } Main { Students student0= new Students("Jack",19,"Higschool") ArrayList <Students> Class= new ArrayList(); Class.add(student0) } // I am not a expert, hope it works for someone.
