Project Question Urgent?

[newtocs]

So I'm making this gradebook project and I'm so close to being finished but I'm stuck on how to remove a student from the array. I have to display a list of students and let the user select one (already done), i just don't know how i would take out that student. I know i need to change the length of the array and take the student out, I just don't know how. HELP!! thanks sorry gotta add the code
Code

public static void removeStudent(String []studentName, int [] studentGrade, int size){
int choice;
for (int i=0; i<size; i++){
System.out.print (i +" "+studentName [i]+" "+studentGrade[i]);
}
System.out.print ("Which student would you like to remove?");
choice = kb.nextInt();
}

ya it's in methods just assume everything else works heres the beginning
int choice;
int size = 0;
String studentName[]= new String [25];
int studentGrade[]= new int [25];



out.println("Please enter your name");//Allows user to make choice
String name = kb.nextLine();
do {
out.println("\n\n*******" + name + "'s Gradebook*******");
out.println("1. Add a student");
out.println("2. Update a student's grade");
out.println("3. Remove a student");
out.println("4. View the gradebook");
out.println("5. Display the highest grade");
out.println("6. Quit");
out.print("\nPlease enter your selection: ");

choice = kb.nextInt();

//Clears the buffer
kb.nextLine();

switch(choice) {
case 1://Add a student
addStudent(studentName, studentGrade, size);
size ++;
break;

case 2:// Update a student's grade
updateGrade (studentName, studentGrade, size);

break;

case 3: //Remove a student.

break;

case 4://View the gradebook.
viewBook (studentName, studentGrade, size);

break;

case 5://Display the highest grade.
HighGrade (studentName, studentGrade, size) ;

break;
case 6://Quit
out.println("Thanks for using the FriscoCorp system.");

}
}while(choice != 6);

you can't change the length. Arrays have a fixed size ArrayLists are dynamic and can be changed on the fly. To remove a student from the list you can just set array[i] = null, where i = the students location.
