我到处寻找,但我找不到与在类构造函数中初始化数组相关的任何内容。
这是我尝试创建的课程:
public Sandwich(char b, String m, String c, String[] e)
{
setBread( b );
setMeat( m );
setCheese( c );
setExtras( e );
}
这是我尝试初始化数组:
public static void main(String[] args)
{
Sandwich[] order;
order = new Sandwich[3];
order[0] = new Sandwich('s', "pastrami", "swiss", extras[2] = {"mayo", "extra meat"} )
order[1] = new Sandwich();
}
我不知所措。
答案 0 :(得分:1)
选项1:使用 SELECT mobile_no FROM A
WHERE NOT EXISTS(SELECT mobile_no
FROM B where A.mobile_no = B.mobile_no).
制作和数组:
new
选项2:使用VarArgs:
将构造函数重新定义为:
new Sandwich('s', "pastrami", "swiss", new String[]{"mayo", "extra meat"});
将值传递给构造函数,从第4个参数开始,所有都是数组元素:
public Sandwich(char b, String m, String c, String... e)

你可以试试这个:
bot.use({
recieve: function(event, next){
locale = event.textLocale; // you can use textLocale
console.log("event runs");
eventTimestamp = event.timestamp; // this event also provides timestamp
next(); // don't forget to call next
}
});
