Exemplo

public class ClassA { private BufferedWriter writer; public void makeWriter (Writer w) { writer = new BufferedWriter(w); //executar algo... } }

Solução

Para evitar fugas de recursos, certifique-se de que close() seja chamado em cada java.io.BufferedWriter. Nota: Essa regra se aplica a qualquer forma de construtor BufferedWriter.

public class ClassA { private BufferedWriter writer; public void makeWriter (Writer w) { writer = new BufferedWriter(w); //executar algo... try { writer.close(); } catch(IOException ioe) { //desempenhar manipulação de exceção } } }
