Java Loop not exiting properly when using boolean expression (JAVA) - Newbie - regex

Question

Everytime I run the my function SearchByID it won't return the necessary boolean operators that I needed. The method reads to the Employee.txt files and read files one after another. What I did is I created a String array to store the splitted strings, and doing the String.equalsIgnorCase() method to check if the corresponding matches w/ the data on the file. Here is the code for the method
Code: SearchByID
public static boolean SearchByID(String ID){
boolean bool = false;
int idLoc = 3;
try(BufferedReader bufr = new BufferedReader(new FileReader(EMPLOYEE_TXT))){
String line = bufr.readLine();
/*Split the records into an array*/
String[] lines;
while(line !=null){
//do the macthing of data here
lines = line.split(";");
if(lines[idLoc].equalsIgnoreCase(ID)){
bool = true;
break;
}else{
bool = false;
break;
}
}
bufr.close();
}catch(Exception ex){
ex.printStackTrace();
}
return bool;
}
Here is the implementation of the method SearchByID();
System.out.print("Search user by ID:");
String strID = sID.nextLine();
if(IOLibraries.SearchByID(strID)){
System.out.println("A match has been found");
}else{
System.out.println("No match found");
}
Content of the Employee.txt
kadi,bens;male;baliwasan grande;88-11;99111;arg11#gmail.com;400.0
doe,john;male;11311 asdd;99811;9911331;asdf#.sdfcom;500.0
What I really need to do is I need to read all the data on the file after that it should return the correct boolean values in order search for all the users on the Employee.txt file.
I could not retrieve if I search the values below the first entries. For example if i search for id 88-11 I could retrieve the data properly, however if I search below the first entry such as 99811 it would return false or "No match found" even if it is in the Employee.txt files.

The problem is you will always break out from the loop after reading the first line.
while(line !=null){
//do the macthing of data here
lines = line.split(";");
if(lines[idLoc].equalsIgnoreCase(ID)){
bool = true;
break;
}else{
bool = false;
break;
}
}
Note the else block. If first line does not match the ID, it will go into the else block, which declare that it is not found, and breaking out.
What you should do is
initialize bool (or better call it found) as false before the loop (for which you have done already)
Only break out of loop if you found the matching line
i.e. change the loop to something like
while(line !=null){
lines = line.split(";");
if(lines[idLoc].equalsIgnoreCase(id)){
found = true;
break;
}
}
