我的代码给了我错误,不确定是什么问题 [英] my code giving me errors not sure what is wrong
本文介绍了我的代码给了我错误,不确定是什么问题的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!
问题描述
LinkedList SongList = new LinkedList();
jbtDisplay.addActionListener( new ActionListener(){
public void actionPerformed(ActionEvent e){
disp.setText( );
for ( int index = 1 ; index < = SongList.getLength(); index ++){
disp.append( 条目编号\t: + index + < span class =code-string> \ n + SongList.getEntry(index)+ \ n \\ n);
}
updateEntry();
}
});
解决方案
HI,
您可以使用SongList.size(); in getlength()和
SongList。 get (index) getEntry ()并查看如果它解决问题并达到目的
HI
您可以使用以下代码,看看它是否符合要求
< pre lang =cs> LinkedList SongList = new LinkedList();
jbtDisplay.addActionListener( new ActionListener(){
public void actionPerformed(ActionEvent e){
disp.setText( );
for ( int index = 1 ; index < = SongList.size(); index ++){
disp.append( 条目编号\t: + index + < span class =code-string> \ n + SongList。 get (index)+ \ n \ n);
}
updateEntry();
}
} );
它是否给你和IndexOutOfBoundsException?如果是这样,请尝试下一件事:index< songlist.size()>< =这意味着程序将尝试访问额外的元素。
祝你好运。
LinkedList SongList=new LinkedList();
jbtDisplay.addActionListener(new ActionListener(){
public void actionPerformed(ActionEvent e){
disp.setText("");
for(int index =1; index <= SongList.getLength(); index++){
disp.append("Entry number\t:" + index + "\n" + SongList.getEntry(index) + "\n\n");
}
updateEntry();
}
});
解决方案
HI,
You could use theSongList.size();in place of getlength()and SongList.get(index) for getEntry() and see if it resolves the issue and serves the purpose
HI
You could use the following code and see if it serves the purpose
LinkedList SongList=new LinkedList(); jbtDisplay.addActionListener(new ActionListener(){ public void actionPerformed(ActionEvent e){ disp.setText(""); for(int index =1; index <= SongList.size();index++){ disp.append("Entry number\t:" + index + "\n" + SongList.get(index) + "\n\n"); } updateEntry(); } });.
Is it giving you and IndexOutOfBoundsException ? If that so try the next thing: index<songlist.size()><= it means that the program will try to access an extra element.
Best regards.
