Answer 1

In these lines
// put libary into array
public void insert(String title, String author, int ypub)
{
ypub[nElems] = new libary(title, author, ypub);
nElems++; // increment size

how can you have the same name on an array on the left side and an integer inside the parans on the right side?

Answer 2

There may well be a malicious application. the will arises to evaluate a gadget fix to the earliest date then delete each and each and each and all of the previous gadget fix dates. the will arises to maintain important stuff. additionally the will arises to comb up on the thank you to prepare the living house living house windows record gadget(each and each and each and all of the learning and manipulations on the keyboard. that's that in case you do no longer desire to play around with Java. If this would not artwork the will arises to reinstall living house living house windows. Or in case you desire to repair Java you're able to could desire to purchase application(no longer my suggestion). you're able to desire to do additionally delete pointless popups and junk that upward push up on a daily basis. have you ever acknowledged into Linux Ubuntu or Mint for Java?
