Do you need to explicitly close the Java keystore input stream?

When using FileInputStream to read the following in keystore, do you need to explicitly close the input stream to stop wasting system resources?

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

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

Is this FileInputStream automatically closed by the load() method or does it require explicit manual intervention?

Solution

Yes, it needs to be close to the end of unnecessary leakage
