How can I append an array in Java programming language?
I am currently working on a task that requires managing of list of students' grades. I have created an array for storing these grades of the students. During the workflow, a new student joined the class and now I need to add his grades too in the array. How can I dynamically append this new grade if a new student is in the Java array without losing any previous data?
In the context of Java programming language, if you want to make Java array append then one smart way to achieve this particular objective is using “ArrayList” which allows you to resize the data set dynamically.
Here is the example given of how you can append the element of an Array list in the context of Java programming language:-
Import java.util.ArrayList;
Public class GradeManager {
Public static void main(String[] args) {
// Suppose you have an ArrayList to store grades
ArrayList grades = new ArrayList<>();
// Add existing grades
Grades.add(85);
Grades.add(90);
Grades.add(78);
// New student’s grade
Int newGrade = 92;
// Append the new grade
Grades.add(newGrade);
// Now, ‘grades’ ArrayList contains the new grade
System.out.println(“Updated grades: “ + grades);
}}This above code will create an array list by the name “grades” and will add the existing grades to it. Moreover, it will append the new grade of a new student by using the feature of “add()” in the array list.
