怎樣設(shè)置Eclipse的java自動(dòng)補(bǔ)全
設(shè)置Eclipse的java自動(dòng)補(bǔ)全步驟如下：
第一步：打開編譯器然后再點(diǎn)開一個(gè)java文件。
第二步：在文件里右擊鼠標(biāo)，然后再選擇Preferences。
第三步：而后再Preferences里選擇java
第四步：再選擇Editor,再選擇Content Assist
第五步：再在我所圈出的地方設(shè)置時(shí)間（200）和字母（.ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz），而后點(diǎn)擊ok即可。
eclipse的設(shè)置界面里面還可以調(diào)整整體的字體大小、編輯器的背景顏色等，還有一個(gè)保存時(shí)自動(dòng)格式化，可以免去很多不規(guī)范的代碼。

public?class?Manager?extends?Employee?{
private?String?department;
public?String?getDepartment()?{
return?department;
}
public?void?setDepartment(String?department)?{
this.department?=?department;
}
public?Manager(String?name){
super(name);
}
public?Manager(String?name,String?department){
super(name);
this.department?=?department;
}
}
public?class?Main?{
public?static?void?main(String[]?args)?{
Scanner?sca?=?new?Scanner(System.in);
String?str?=?sca.next();
String?str1?=?sca.next();
Manager?m?=?new?Manager(str,?str1);
System.out.println("name:"+m.getName()+"?department:"+m.getDepartment());
}
}
如果Main類中不想用getName()和getDepartment()的話，需要在Manager中把name和department定義成public
