出現(xiàn)原因：tomcat對(duì)保存硬盤(pán)的session讀取失敗 解決方法：打開(kāi)TOMCAT的安裝目錄，在WORK文件夾找到Catalina\localhost\你的工程名所在文件夾下， 把里面的session.ser刪除即可。 但是我進(jìn)入到我的項(xiàng)目下居然沒(méi)搜索出這個(gè)文件，最后搜索出localhost文件夾下所有的session.ser文件并刪除掉才解決了該問(wèn)題。 你試試吧

這是慕課網(wǎng)的問(wèn)題，不用太計(jì)較，試試下面這個(gè)：

public?class?HelloWorld{
????public?static?void?main(String[]?args)?{
????????String?name="愛(ài)慕課";
????????char?sex='男';
????????int?num=18;
????????double?price=120.5;
????????boolean?isOK=true;
????????System.out.println(name);
????????System.out.println(sex);
????????System.out.println(num);
????????System.out.println(price);
????????System.out.println(isOK);
????}
}

求采納！

代碼可以通過(guò)~

姓名:愛(ài)慕課??性別:男
中獎(jiǎng)數(shù)字:18價(jià)格:120.5
確定要關(guān)閉程序嗎:true

你的意思是不能通過(guò)慕課網(wǎng)這里是嗎？因?yàn)槟秸n網(wǎng)對(duì)答案是模式匹配，你應(yīng)該使用它們給你的變量名稱(chēng)。這樣就能通過(guò)了
