我有这个Java类,
public class sample {
public Integer foo1(Integer x){
return x+5;
}
}
class SubClass extends sample{
public Integer foo2(Integer x){
return x+100;
}
}
对于Jython,我想称foo2
班SubClass
.我最终得到了以下 Python 代码,
import SubClass, sample
java_file = SubClass()
print java_file.foo2(3)
但是运行 Python 代码会返回此错误,
AttributeError: 'SubClass' object has no attribute 'foo2'
我还想打印一个类的超类及其签名,包括公共、抽象等属性。
有没有办法做到这一点?谢谢!
您必须首先创建一个实例...调用方法...如以下示例:
Beach.java
public class Beach {
private String name;
private String city;
public Beach(String name, String city){
this.name = name;
this.city = city;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public String getCity() {
return city;
}
public void setCity(String city) {
this.city = city;
}
}
Using Beach.java in Jython
>>> import Beach
>>> beach = Beach("Cocoa Beach","Cocoa Beach")
>>> beach.getName()
u'Cocoa Beach'
>>> print beach.getName()
Cocoa Beach
