Implementing generics for java 1.6


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.
