how to get a constant in java with class

Question

basically I need to get a constant for a class however I have no instance of the object but only its class. In PHP I would do constant(XYZ); Is there a similar way

Answer 1

I am not sure what you want to get out. But it shouldn't be too difficult to show you an example.

Lets say you have a Class Foo with property bar.

Class Foo {
    private final String bar = "test";
    public String getBar() {return bar;}
}

Now to get this through reflection you would:

Class fooClass = Foo.class;
Object fooObj = fooClass.newInstance();
Method fooMethod = fooClass.getMethod("getBar");
String bar = (String) fooMethod.invoke(fooObj);

Now you will get value of method getBar() in bar variable
