请问线上 网页版的JAVA编辑器
在:
https://www.tutorialspoint.com/compile_java_online.php
在:
https://www.jdoodle.com/online-java-compiler/
在:
https://ideone.com/
/* package whatever; // don't place package name! */
import java.util.*;
import java.lang.*;
import java.io.*;
/* Name of the class has to be "Main" only if the class is public. */
public class Test{
int a;
}
class Ideone
{
public static void main (String[] args) throws java.lang.Exception
{
Test test = new Test();
}
}
Main.java:9: error: class Test is public, should be declared in a file named
Test.java
public class Test{
^
1 error
宣告类别怎麽都不能成功编译成功呢?

1F：推 lycantrope: class has to be "Main" only if the class is public 11/15 21:07
2F：推 LPH66: 你想像这些地方你的程式是放在 Main.java 里编译的就好 11/15 23:34
3F：→ crazybad: 你存档成 Ideone.java 就不会有问题了 11/23 11:45
4F：推 mureka: 基本习惯，一个物件一个档(inner class 不算)，档名跟物件 01/07 23:01
5F：→ mureka: 名相同 01/07 23:01
