Do you need to explicity close a Java KeyStore input stream?

When reading in a KeyStore using a FileInputStream as follows, does one need to explicitly close the input-steam to stop system resources being wasted ?

FileInputStream fin = new FileInputStream("keystore.jks");
KeyStore keystore = KeyStore.getInstance("JKS");
keystore.load(fin, password);

//  Is this line needed ??
fin.close();

Is this FileInputStream closed automatically by the load() method or is explicit manually intervention required?

Solution

  • Is this FileInputStream closed automatically by the load() method or is explicit manually intervention required?

    yes it required to close to over come unnecessary leaks.
