Question

Having trouble with a Zoo Monitoring system. Using NetBeans. i have worked out most of the bugs but now its only printing the first few lines of the text file (it prints the lines that begin with "Details" and not continuing to the rest to find the lines with ***** in them to pop up the Joption pane with the alert for that line. below is the code for both java files, as well as the .txt files its reading from.

ZooMonitor.java

package zoomonitor;

//import needed options

public class ZooMonitor {

private static final Scanner sc=new Scanner(System.in);

public static void main(String[] args) throws FileNotFoundException {
while(true) {
int choice=menu();
if(choice==1) {

// Select animal
int animal = animalSelect();
String Type="";

switch (animal) {
