[英]Create Java object that implements an interface from Matlab
For some reason, I am not able to create a Java object that implements a user-defined interface. 由于某些原因,我无法创建实现用户定义接口的Java对象。
I tried creating a Java object that implements a pre-defined interface and it worked fine. 我尝试创建一个实现预定义接口的Java对象,并且效果很好。
My interface: 我的界面:
public interface Speak
{
public void sayHello();
}
My Class: 我的课:
public class myPerson
implements Speak
{
public myPerson(String arg_firstName, int arg_age)
{
firstName = arg_firstName;
age = arg_age;
}
public String firstName;
public int age;
@Override
public void sayHello() {
// TODO Auto-generated method stub
}
}
For my class to work in eclipse, I had to export my interface as a .jar file, then I added it to the project libraries - and it worked just fine. 为了使我的班级能够在eclipse中工作,我必须将接口导出为.jar文件,然后将其添加到项目库中,并且效果很好。
My Matlab file: 我的Matlab文件:
clc
clear
javaclasspath('/path/to/Speak.jar');
javaclasspath('/path/to/myPerson.jar');
driver_1 = myPerson('Bob', 39);
The error that I'm getting is: 我得到的错误是:
Undefined function or variable 'myPerson'.
If I remove the implements
interface, I can create the object just fine. 如果删除了implements
接口,则可以创建对象。
I suggest you try 我建议你试试
javaclasspath({'/path/to/Speak.jar', '/path/to/myPerson.jar'});
(You need both Speak.jar
and myPerson.jar
on the classpath to instantiate a myPerson
.) (在类路径上需要Speak.jar
和myPerson.jar
来实例化myPerson
。)
