How to get special methods of classes in Java?

I have a class with some methods in Java, as shown below:

public class Class1
{
    private String a;
    private String b;


    public setA(String a_){
        this.a = a_;
    }

    public setb(String b_){
        this.b = b_;
    }

    public String getA(){
        return a;
    }

    @JsonIgnore
    public String getb(){
        return b;
    }
}

I want to get all the methods starting with string get in Class1, which are not declared with the @ jsonignore annotation

What should I do?

Solution

You can use java reflection to iterate over all public and private methods:

Class1 obj = new Class1();

Class c = obj.getClass();
for (Method method : c.getDeclaredMethods()) {
    if (method.getAnnotation(JsonIgnore.class) == null &&
        method.getName().substring(0,3).equals("get")) {
        System.out.println(method.getName());
    }
}
