Java Reflection : Accessing getter method [duplicate]

Question

The code

import java.beans.*
for (PropertyDescriptor pd : Introspector.getBeanInfo(Foo.class).getPropertyDescriptors()) {
    if (pd.getReadMethod() != null && !"class".equals(pd.getName()))
        System.out.println(pd.getReadMethod().invoke(foo));
}

This code returns the getters of the class but I am trying to access the getters in the order of attributes where I can set their values to.

How can I access the getters in particualr order?

What order are you expecting? The JVM does not guarantee any specific ordering. — Chris K

@ChrisK In case if I have id , name , I would like to getid() and then getName(). but the code above doesn't provide any specific order — rashidali

Have you considered sorting, using a custom comparator? eg mkyong.com/java/… — Chris K

DEfine the class, then in the instance get all the methods then use a stream to filter the getters only

public class Pint {

    private int x;
    private int y;
    private int z;

    public int getX() {
        return x;
    }

    public int getY() {
        return y;
    }

    public int getZ() {
        return z;
    }

and then

 Arrays.stream(p.getClass().getDeclaredMethods()).filter(x -> x.getName().contains("get")).forEach(System.out::println);
