Question
JAVA help: create a class with the following SIX methods:
Restrictions:
1.You must use an array of int. You may NOT use ArrayLists and other collections. If in
doubt, ask.
2.Do not add to the instance variables.
3.You may add private methods to support the other methods if desired.
1. OrderedList (int)
a. create an array of the size indicated by the parameter
b. if the parameter is less than 2, create an array of size 2
2. size(): int
a. return the size of the array (maximum number of values that can currently be stored)
3. numEntries():int
a.return the number of integers currently stored in the array
b.this number will range from 0 to the size of the array
4. insert (int): void
a.insert an integer into the array so that the elements are in ascending order
b.do not allow for duplicates in the array
c.if the array is full, do not insert the value
d.do not sort the array
5. delete (int): void
a.find the integer in the array and remove it
b.if the value is not in the array, do nothing
c.if the value is in the array, remove it so that the elements remain in ascending order
6. toString(): String
a. return the values in the array so that all values are separated by a space
b. the string should be “1 2 3” not “1 2 3 “
