common method and method body with one changing method parameter

We have a common method as below:

public class CommomClass()
{
    public String[] commonMethod(Object1 inputObject1)
    {
        String[] output;

        output[0] = (inputObject1.getValue1());
        output[1] = (inputObject1.getValue2());

        return output;
    }
}

The same method can be used in other classes by changing the method parameter to Object2 inputObject2. How do we accomplish this without redundant code?

The classes Object1 and Object2 could implement an interface:

public interface HasValues {

    public String getValue1();
    public String getValue2();
}

And your common method could be redefined to take an instance of that interface:

public String[] commonMethod(HasValues hasValues) {

    String[] output = new String[2];

    output[0] = hasValues.getValue1();
    output[1] = hasValues.getValue2();

    return output;
}
