Calling methods of a Java subclass using Jython

Curious Published at Dev

Curious

I have this Java class,

public class sample {
        public Integer foo1(Integer x){
            return x+5;
        }
    }
class SubClass extends sample{

    public Integer foo2(Integer x){
        return x+100;
    }
}

And with Jython I want to call foo2 of the class SubClass. I ended up with the following Python code,

import SubClass, sample
java_file = SubClass()
print java_file.foo2(3)

But running the Python code returns this error,

AttributeError: 'SubClass' object has no attribute 'foo2'

I also want to print the super class of a class and it's signature including the attributes like public, abstract, etc.

Is there a way to do this? Thanks!

You have to first create a instance... the invoke the method... like the following example:

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
