Do the following for the Array Insert the element in the array,delete an element from the array,search for a particular element Create multiple thread

Posted By: Mena Schmidt     Category: Java     Views: 10698

Write a program which creates a one dimensional array. Do the following for the Array.
1. Insert the element in the array
2. delete an element from the array
3. search for a particular element
Create multiple threads which do the above things. Implement the program so that consistency is maintained for the array.
