Answer 1

public void showdata()
{
//System.out.println(id+""+name);
System.out.println(id + " " + name + " " + age);
}

Missing a + operator between <name> and " ".
First print statement is redundant, so I guess it can be commented or removed.

Answer 2

Also if you want to have a different showdata() for when age is not part of the object you will need to create a showdata() to be used in that case.

Answer 3

// if 0 is not valid age

public void showdata() {
System.out.printf( "id:%d, name:%s%s\n", id, name,
age > 0 ? ", age:" +age : "" );
}
