    program should provide the operations:
    Add a new asset into the array (duplicate entries are not allowed).
    Search for an asset.
    Amend the details of an asset.
    Write-off an asset
    List details of all assets, each on a different line with line numbering.

    all i have done, but left the write-off asset i cant do it. i tried many way , i use the amend asset method to make a change but failed. any1 mind too help? here my source file.

    import java.util.*;

    Do you get errors from the program? Please copy and paste them here.

    What is the output of the program supposed to look like?

    Also please use code tags to save the code formatting. You posted code is hard to read.
