class constructor cannot be accessed by outside package
提问by Joe
so i can't find a question already asked that answers my exact problem. I have a package that i wrote in eclipse that i exported as a jar library to use in the processing ide. in processing i have a sketch that has a class that calls a class that is in the package. when i try to compile i get this error:
所以我找不到已经提出的问题来回答我的确切问题。我有一个我在 eclipse 中编写的包，我将它导出为 jar 库以在处理 ide 中使用。在处理中，我有一个草图，它有一个类，该类调用包中的一个类。当我尝试编译时出现此错误：
Pirate(processing.core.PApplet,java.lang.String,processing.core.PVector,float,float,int,int) is not public in fsg.pvzclone.pirateunits.Pirate; cannot be accessed from outside package
[javac] fsg.pvzclone.pirateunits.Pirate pirate1 = new fsg.pvzclone.pirateunits.Pirate(this, "Pirate", pinPoint, pWidth, pHeight, 1, 1).displayPirate();
does anyone know why i can't access the class? I have both the class and constructor set as public, so i'm not sure why the class can't be accessed. any help would be greatly appreciated.
有谁知道为什么我无法访问课程？我将类和构造函数都设置为public，所以我不确定为什么无法访问该类。任何帮助将不胜感激。
CONSTRUCTOR CODE:
构造器代码：
package fsg.pvzclone.pirateunits;
import processing.core.*;
public class Pirate {
public String pirateClass;
int classId;
PVector pinPoint;
float width;
float height;
int id;
PApplet parent;
public Pirate(processing.core.PApplet _parent, String _pirateClass, PVector _pinPoint,
float _width, float _height, int _classId, int _id) {
parent = _parent;
pirateClass = _pirateClass;
classId = _classId;
width = _width;
height = _height;
pinPoint = _pinPoint;
id = _id;
}
public void displayPirate() {
parent.fill(13, 183, 20, 255);
parent.stroke(7, 59, 9, 255);
parent.rect(this.pinPoint.x-this.width/2, (float)(this.pinPoint.y-this.height*.75), this.width, this.height);
}
}
CODE CALLING PIRATE CLASS:
代码调用海盗类：
fsg.pvzclone.pirateunits.Pirate pirate1 = new fsg.pvzclone.pirateunits.Pirate(this, "Pirate", pinPoint, pWidth, pHeight, 1, 1).displayPirate();

If the Pirate class is 1:1 like shown, then I suspect you have an old version in classpath somewhere. Double-check the classpath for old versions, both .java and .class.
如果 Pirate 类是如图所示的 1:1，那么我怀疑您在类路径中的某个地方有一个旧版本。仔细检查旧版本的类路径，包括 .java 和 .class。

try to create public default constructor in Pirate class and try to call it as:
尝试在 Pirate 类中创建公共默认构造函数并尝试将其调用为：
public class Pirate{
public Pirate () {}
....
}
calling code:
调用代码：
fsg.pvzclone.pirateunits.Pirate emptyPirate1 = new fsg.pvzclone.pirateunits.Pirate();
And check you still get the same error msg?
并检查您是否仍然收到相同的错误消息？

Not sure this is your problem, but it is a problem and too long for a comment - you should replace;
不确定这是你的问题，但这是一个问题，评论太长了 - 你应该更换；
fsg.pvzclone.pirateunits.Pirate pirate1 = new fsg.pvzclone.pirateunits.Pirate(this, "Pirate", pinPoint, pWidth, pHeight, 1, 1).displayPirate();
with:
和：
fsg.pvzclone.pirateunits.Pirate pirate1 = new fsg.pvzclone.pirateunits.Pirate(this, "Pirate", pinPoint, pWidth, pHeight, 1, 1);
pirate1.displayPirate();
Since displayPiratereturns nothing, not a pirate.
因为displayPirate什么都不返回，不是海盗。
