Java bean

[Manigandan Velraj]

hi,

Is there any API to validate the structure of a java bean. Given a java file, i should be able to say if it is a valid java bean file (ie. it should have only have getters and setters methods and not other methods.. )

Thanks in advance.

Somehow this sounds wrong to me, but I could be mistaken.
Consider the following code.

public class Person {

	private String firstName;
	private String lastName;
	
	public Person() {
		// TODO Auto-generated constructor stub
	}
	
	//Getter and setters
	
	public String getDisplayName() {
		return this.firstName+" "+this.lastName;
	}
}

Thanks for the reply,

But i need to check if a file contains only variables , getters , setters.

If a file contains methods (as in your example, getDisplayName) the file should be rejected.

Thanks.

Why should that be rejected? getDisplayName() is a getter too, for a read-only property based on two other properties.

Anyway, if you change the requirement from "Java file" to "Java class" you can use reflection, starting with Class.getMethods().

Sounds as if you could use reflection and getMethods() or similar.
