Exception in thread "AWT-EventQueue-0" java.lang.NumberFormatException: For input string: "FALSE"

Question

My Code:

public class BehemothSelectGUI extends javax.swing.JFrame {
private static DBUtil db = new DBUtil();
private static Populate populate = new Populate();
static int WepHitPoints;
static int ShoulderHitPoints;
static int ChestHitPoints;
static int WristHitPoints;
static int HelmHitPoints;
static int WepAttack;
static int HelmDef;
static int ShoulderDef;
static int WristDef;
static int ChestDef;
static int HelmMoveSpeed;
static int WepMoveSpeed;
static int ChestMoveSpeed;
static int ShoulderMoveSpeed;
static int WristMoveSpeed;

private void cmbMothHeadActionPerformed(java.awt.event.ActionEvent evt) {                                          
    String data[][] = db.selectAll("tblBehemoth");

    for (int i = 0; i < data.length; i++) {
        if (data[i][1].equals((String) cmbMothHead.getSelectedItem())) {
            HelmHitPoints = Integer.parseInt(data[i][2]);
            HelmDef = Integer.parseInt(data[i][4]);
            HelmMoveSpeed = Integer.parseInt(data[i][5]); //StackTrace error
            break;
        }
    }

}

Error:

I have been using the Integer.parseInt(data[i][number] converter for other variables but only this one throws an error.

UPDATE: When I sysoutLine it returns 'FALSE'. I still have no idea how it is returning false as in my database col 5 are number

System.out.println(data[i][5]);

And which part of the exception message do you not understand? The value you give to *parse* is "FALSE". That is not a number. So you cant parse it into an int. We can't tell you why you try to parse a string containing a boolean value as number. — GhostCat, Aug 26 '17 at 06:35
Please check if `data[i][5]` points to the right column in the fetched data — Stefan Freitag, Aug 26 '17 at 06:36

And unrelated: learn about java basics first. For example: why to **not** make all fields of your class static. A person who doesn't know why that is a bad idea is most likely **not** ready to create swing UIs or interact with databases. There is that saying: learn to crawl before trying to run. — GhostCat, Aug 26 '17 at 06:38

The Integer.parseInt(String str) java docs very clearly states that.

Throws: NumberFormatException - if the string does not contain a parsable integer.

And FALSE is not a parsable integer.

All inferreed form your stack trace here:

Yes, I get that but I'm not trying to parse FALSE. I'm getting the data from my Database Column which is set to long integers – Stuart Campbell Aug 26 '17 at 06:39
@StuartCampbell You might have to share the entire `data[][]` value in that case to validate. The log reads the input string as `FALSE` from somewhere atleast. – Naman Aug 26 '17 at 06:42
