Is possible getMethods in order using reflections? [duplicate]

Question

Possible Duplicates:
Java Reflection: Getting fields and methods in declaration order
Java. Get declared methods in order they apear in source code

Suppose I have this class

Is possible take the getters methods in order?

public class ClassA {

private String name;
private Integer number;
private Boolean bool;

public String getName() {
    return name;
}

public void setName(String name) {
    this.name = name;
}

public Integer getNumber() {
    return number;
}

public void setNumber(Integer number) {
    this.number = number;
}

public Boolean getBool() {
    return bool;
}

public void setBool(Boolean bool) {
    this.bool = bool;
}

}

I have try this..

for (Method method : ClassA.class.getDeclaredMethods()) {
    if (!(method.getReturnType().toString().equals("void"))) {
        method.invoke(obj, new Object[0])));
    }
}

I got this from documentation

...The elements in array returned are not sorted and are not in any particular order...

So.. is just that? Exists some alternative or I just have to implement something?

Answer 1

You can add to each method your own @annotation, which contains a number. Then get all the getter methods, and use your custom sorter to sort them depending on the number you passed to the annotation using Collections.sort().

Eg:

@SortedMethod(100)
public String getName()
{
    return name;
}

@SortedMethod(200)
public String getNumber()
{
    return number;
}
