java - 编译java代码错误

Question

当我想编译名为 SetPoint.java 的文件时出现错误:

SetPoint.java:5: error: cannot find symbol
        Point point = new Point();
        ^
  symbol:   class Point
  location: class SetPoint
SetPoint.java:5: error: cannot find symbol
        Point point = new Point();
                          ^
  symbol:   class Point
  location: class SetPoint
2 errors

我在名为 xyz 的文件夹中有这两个文件(Point.java 和 SetPoint.java)。我不知道我做错了什么。如果我在 IntelliJ 中做同样的事情，它就可以正常工作。

package xyz;

public class Point {
    int coorX;
    int coorY;
}

.

package xyz;

public class SetPoint {
    public static void main(String args[]){
        Point point = new Point();
        point.coorX = 10;
        point.coorY = 20;

        System.out.println("Coordinate of point: ("+point.coorX+", "+point.coorY+")");
    }

}

Answer 1

同时编译两个java文件，

javac *.java

或

javac SetPoint.java Point.java
