Sebb commented on LANG-1402: ---------------------------- Yes, I mean actual code examples. Does the code in question really not care if the array is null or empty? I would have expected such conditions to already been handled in production code. > ArrayUtils should have null and index-safe get methods. > ------------------------------------------------------- > > Key: LANG-1402 > URL: https://issues.apache.org/jira/browse/LANG-1402 > Project: Commons Lang > Issue Type: New Feature > Components: General > Reporter: Mark Dacek > Priority: Minor > Original Estimate: 24h > Remaining Estimate: 24h > > There should be a safe way to retrieve a value from array without having to > check for null and length. It would be a very simple implementation but could > save developers a great deal of time in writing and testing. > > Something like > > {code:java} > String[] a = null; > ArrayUtils.get(a, 5); //returns null > a = new String[5]; > ArrayUtils.get(a, 10); // returns null > > a[0] = "Hello World"; > ArrayUtils.get(a, 0); // returns "Hello World" > {code} > > We could handle a few other cases - a default return value. The > tricky/annoying thing is the need to cast everything in order to make this -- This message was sent by Atlassian JIRA (v7.6.3#76005)
