//使用GridLayout在Panel裡面切出3x3的格子，使按鈕排整齊
jplPanel.setLayout(new GridLayout(3,3));

//以下將方塊上的數字打亂(使用洗牌演算法產生不重複亂數)
//詳細演算法可參考以下文章:

for(int i=0;i<9;i++){

//把Panel加進去Fram
jtfMainFrame.setVisible(true); //讓Fram顯示出來

//檢驗按下去為哪一顆按鈕
for(int i=0;i<9;i++){
if(jbnButton[i]==e.getSource())
{
ilate=i;
//JOptionPane.showMessageDialog(null,jbnButton[i].getText()+" "+i);
}}

//當知道按下去按鈕是哪一顆之後，便須判斷其周圍的按鈕
//確認空白按鈕(上下左右)周圍，則按下去的按鈕數字與空白按鈕互換
//以下為判斷的程式碼

if(ilate>=3&&ilate<=8){
if(" ".equals(jbnButton[ilate-3].getText()))
{
late=jbnButton[ilate].getText();
jbnButton[ilate].setText(jbnButton[ilate-3].getText());
jbnButton[ilate-3].setText(late);
}}

if(ilate<=5&&ilate>=0){
if(" ".equals(jbnButton[ilate+3].getText()))
{
late=jbnButton[ilate].getText();
jbnButton[ilate].setText(jbnButton[ilate+3].getText());
jbnButton[ilate+3].setText(late);
}}

if(ilate<8&&ilate>=0){
if(" ".equals(jbnButton[ilate+1].getText()))
{if((ilate%3)!=2){
late=jbnButton[ilate].getText();
jbnButton[ilate].setText(jbnButton[ilate+1].getText());
jbnButton[ilate+1].setText(late);
}}}

if(ilate>=1&&ilate<=8){
if(" ".equals(jbnButton[ilate-1].getText()))
{if((ilate%3)!=0){
late=jbnButton[ilate].getText();
jbnButton[ilate].setText(jbnButton[ilate-1].getText());
jbnButton[ilate-1].setText(late);
}}}

//以下為破關檢驗的程式碼
//當按鈕排列成如下圖所示，則跳出MsgBox顯示破關成功!!

for(int m=0;m<9;m++)
{
slate+=jbnButton[m].getText(); if("14725836 ".equals(slate)){JOptionPane.showMessageDialog(null,"恭喜你成功");}}System.out.println("'"+slate+"'");}}
