Defining a JavaBean

Take the binary message 06C785969987850400000012 for example.

It is an array of bytes. The 06 is a length indicator indicating that the following 6 bytes C78596998785 should be recognized as a field. The legacy application parses it into a String, and the encoding is cp937. C78596998785 is the binary representation of the String "George". Byte 04 is also a length indicator, indicating that the following 4 bytes 00000012 should be recognized as a field. In this case, the legacy application parses it into an integer, and 00000012 is the binary representation of integer "18".

In the view of modern programming language, the binary message is a data object with two fields: the first one is String and the second field is an integer.

Following is an example, which defines a JavaBean to hold data in Java™ world:
public class Person {
	private String name;	
	private int age;	
	public int getAge() {
return age;
	}
	public void setAge(int age) {
		this.age = age;
	}
	public String getName() {
		return name;
	}
	public void setName(String name) {
		this.name = name;
	}
}
