異常在線程 「AWT-EventQueue的 - 0」 java.lang.NumberFormatException：對於輸入字符串： 「FALSE」

Question

我的代碼：

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; 
     } 
    } 

} 

錯誤：

我一直在使用的Integer.parseInt（數據[I] [數字]轉換爲其他變量，但只有這一個引發錯誤

UPDATE：。 當我sysoutLine返回「FALSE」我仍然不知道它是如何返回FAL因爲在我的數據庫列5號碼是

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

Answer 1

該Integer.parseInt(String str) java文檔非常清楚地表明。

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

而且FALSE不是一個可分析的整數。

所有inferreed這裏形成的堆棧跟蹤：
