Exception in thread "main" java.lang.Error: Unresolved compilation (PhraseOMatic)
提问by OpMt
I tried to run the code from Head First Java as the following:
我尝试从 Head First Java 运行代码，如下所示：
public class PhraseOMatic {
public static void main(String[] args){
String[] wordListOne = {"24/7", "mult-iTier", "30,000 foot", "B-to-B", "win-win", "front-end", "web-based", "pervasive", "smart", "six-sigma", "critical-path", "dynamic"};
String[] wordListTwo = {"empowered", "sticky", "value-added", "oriented", "centric", "distributed", "clustered", "branded", "outside-the-box", "positioned", "networked", "focused", "leveraged", "aligned", "targeted", "shared", "cooperative", "accelerated"};
String[] wordListThree = {"process", "tipping-point", "solution", "architecture", "cor competency", "strategy", "mindshare", "portal", "space", "vision", "paradigm", "mission"};
int oneLength = wordListOne.length;
int twoLength = wordListTwo.length;
int threeLength = wordListThree.length;
int rand1 = (int) (Math.random() * oneLength);
int rand2 = (int) (Math.random() * twoLength);
int rand3 = (int) (Math.random() * twoLength);
String phrase = wordListOne[rand1] + " " + wordListTwo[rand2] + " " + wordListThree[rand3];
System.out.println("What we need is a " + phrase);
}
}
and it is here that I receive this error:
正是在这里我收到了这个错误：
Exception in thread "main" java.lang.Error: Unresolved compilation problem:
线程“main”中的异常 java.lang.Error：未解决的编译问题：
at PhraseOMatic.main(apples.java:2)
I see from the error that the problem is in line 2, but I can identify the error
我从错误中看到问题在第 2 行，但我可以识别错误

Have a look at exception trace (PhraseOMatic.main(apples.java:2)). Your public class PhraseOMaticmust be saved with PhraseOMatic.javafile. Name of top-levelpublic class and .java file must be same.
查看异常跟踪 ( PhraseOMatic.main(apples.java:2))。您的公共课程PhraseOMatic必须与PhraseOMatic.java文件一起保存。top-level公共类和 .java 文件的名称必须相同。

Just look at PhraseOMatic.main(apples.java:2). Your file is named apples.java, but in Java your files HAVE to have the same name as your classes. In your case PhraseOMatic.java.
看看吧PhraseOMatic.main(apples.java:2)。您的文件名为apples.java，但在 Java 中，您的文件必须与您的类同名。在你的情况下PhraseOMatic.java。

your stake trace:
您的权益追踪：
PhraseOMatic.main(apples.java:2)
So you are missing to run java to level class; your java main class is PhraseOMatic
所以你缺少运行 java 到 level 类；你的java主类是PhraseOMatic
