我尝试运行Head First Java中的代码,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);
}
}
正是在这里我收到了这个错误:
线程“main”中的异常java.lang.Error:未解决的编译问题:
at PhraseOMatic.main(apples.java:2)
我从错误中看到问题出在第2行,但我可以识别错误
答案 0 :(得分:2)
查看异常跟踪(PhraseOMatic.main(apples.java:2)
)。您的公开课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。
答案 1 :(得分:0)
看看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名称相同。在您的情况下PhraseOMatic.java
。
答案 2 :(得分:0)
您的赌注:
PhraseOMatic.main(apples.java:2)
所以你缺少运行java到level class;你的java主类是PhraseOMatic
