一个常见的例子是在使用 Java 的 Stream API 时,如果代码书写不当,可能会引发编译器错误。例如: importjava.util.Arrays;importjava.util.List;publicclassExample{publicstaticvoidmain(String[]args){List<String>list=Arrays.asList("apple","banana","cherry");list.stream().map(s->s.toUpperCase())// ...
import java.util.List;/** * Created by MyWorld on 2016/3/21.*/ public class RefactorOperate { public static void main(String[] args) { List<String> seasonList = new ArrayList<String>(Arrays.asList("Spring", "Summer", "Autumn", "Winter")); for (String season : seasonList...

除了此范围内,其他区域是可以任意填写的,内容不会提交到leetcode,可以增加一些可以本地调试的内容,例如:import java.util.Arrays; 所以,这两行内容是不能被删除和修改的,否则将识别不到提交的内容。 看到这里,祝福你,你成功了。剩下的就是右键运行=》运行成功!!!

今天碰到了一个空指针异常,代码看起来很普通,一点也看不出会空指针,后来debug才发现了问题所在。这是很容易忽略的地方,记一笔,不知道大家有没有碰到过。 下面代码是根据这个问题写的。 代码语言:javascript 复制 importjava.util.ArrayList;publicclassModel{staticArrayList<String>list;staticvoidread(ArrayList<String...
