拼写检查代码实现java 拼写检查的快捷键

IT技术方法

如何写一段java代码让你一个程序能自己动判断从错误的任务开始重新运行！有必要弄得这么麻烦吗拼写检查代码实现java？最直接拼写检查代码实现java的就是用oracle拼写检查代码实现java的job，全部都在数据库内部执行，不用担心链接会断掉 。
在外部实现的话也用高级点的存储过程，速度快，稳定性好 。有些业务不要完全去依赖外部程序 。想拼写检查代码实现java你这样的情况完全可以用job实现
这两道题代码怎么写java？创建一个名字为“ReportCard”的类，然后用下边的内容全部替换掉，你会成为全班最亮的仔 。
import java.util.HashMap;
/**
* 学生成绩单
*/
public class ReportCard {
public static void main(String[] args) {
ReportCard reportCard = new ReportCard("张三", "070602213");
reportCard.set("语文", 80.0);
reportCard.set("数学", 59.5);
reportCard.set("英语", 66.0);
reportCard.set("java", 80, 99.0);
reportCard.set("数据库", 80, 66.0);
reportCard.set("毛概", null);
System.out.println(reportCard.getStudentName() + "语文分数:" + reportCard.get("语文"));
System.out.println(reportCard.getStudentName() + "数学考核结果:" + (reportCard.isPassed("数学") ? "合格" : "不合格"));
System.out.println(reportCard.getStudentName() + "期末是否挂科：" + (reportCard.isAllPassed() ? "否" : "是"));
}
