『壹』 java日歷記事本內容如何保存到資料庫
1、可以使用簡單的資料庫，如Sql Server, MySql ,等（這個需要在Java JDK中添加鏈接資料庫的jar包，或者將對應的jar包加到你的Java Project中）；
2、可以考慮使用Java的簡單存儲，如下：
importjava.awt.event.ActionEvent;
importjava.awt.event.ActionListener;
importjava.io.File;
importjava.io.RandomAccessFile;
importjavax.swing.JButton;
importjavax.swing.JFrame;
importjavax.swing.JOptionPane;
{
=1L;
privateJButtonjb=null;
privateinti=0;
publicvoidinit(){
jb=newJButton("保存");
jb.addActionListener(this);
}
publicS(){
init();
this.setLayout(null);
this.setSize(800,600);
this.setVisible(true);
this.setDefaultCloseOperation(DISPOSE_ON_CLOSE);
this.add(jb).setBounds(100,200,120,60);
}
//path為保存文件路徑，content為輸入框內容
publicvoidSave(Stringpath,Stringcontent){
Filefile=newFile(path);
if(!file.exists()){
file.mkdir();
}
if(file.isDirectory()){
file.delete();
return;
}
RandomAccessFileraf=null;
try{
raf=newRandomAccessFile(file,"rw");
raf.write(content.getBytes("GBK"));//將內容寫入到固定位置的文件
raf.close();
}catch(Exceptione){
e.printStackTrace();
}
}
@Override
publicvoidactionPerformed(ActionEvente){
//TODOAuto-generatedmethodstub
if(e.getSource()==jb){
Stringcontent=JOptionPane.showInputDialog("");
if(content!=null){
i++;
Stringpath="D:\C"+i+".txt";
Save(path.trim(),content);//保存到你要保存的位置
}else{
//這里還可以做其他操作
JOptionPane.showConfirmDialog(getParent(),"請輸入需要保存的內容!");
}
}
}

『伍』 java程序日歷記事本中：日歷.set(month, month-1, 1);裡面的參數是什麼意思
我們知道DAY_OF_WEEK是獲取當前日期是一周中的第幾天，而一周從周日算起，因此當我們取得這個值之後，為了要正確的截取出隨後的字元串中的那個中文字元，因此它需要減1來達到目的。你只要跟蹤一下程序運行，觀察變數的賦值就會理解它這樣編寫的用意了。
