我在我的 mac 上写了一个程序并通过终端编译它:
cd user/desktop/Code/Program/src/program
javac Program.java
**java Program**
然后我得到这个错误:
Exception in thread "main" java.lang.NoClassDefFoundError: Program (wrong name: program/Program)

有谁知道我该如何解决这个问题？
源代码:
package learning;
public class Learning{
public static void main(String[] args){
String[] wordListOne = {"you are","I know","I eat"};
String[] wordListTwo = {"a poo","a funny","a posh"};
String[] wordListThree = {"Sandwich","person","object"};
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() * threeLength);
String phrase = wordListOne[rand1]+" "+wordListTwo[rand2]+" "+wordListThree[rand3];
System.out.println(phrase);
}
}
