Implementing generics for java 1.6
Question
I'm trying to make this code generic:
public final Object unwrap(Class arg0) {
throw new UnsupportedOperationException();
}
It comes from the Wrapper class (java.sql) and looks originally like this:
<T> T unwrap(java.lang.Class<T> iface) throws java.sql.SQLException;
Solution
public final <T> T unwrap(Class<T> arg0) throws SQLException {
throw new UnsupportedOperationException();
}
which is exactly the same is the definition you pasted.
