Red and Sensual Java: Null-safe access to properties
http://sensualjava.blogspot.com/2007/11/null-safe-access-to-properties.html
Wednesday, November 7, 2007. Null-safe access to properties. First I am going to show a nice side-effect of using properties with google-collections. Like many others I am annoyed to write code of the style. Bar getBarOfThing(Thing thing) {. Bar bar = null;. Foo foo = thing.getFoo();. Bar = foo.getBar(). All the null checks make it unreadable. And heaven forbid I forget one null test. BOOM! Foo = new Function Thing,Foo () {. Public Foo apply(Thing from) {. Return from.getFoo();. Return from.getBar();.

Java , J2EE. Corner of the web where i pen down my tech experience. Sunday, December 23, 2012. Hadoop : Was the job really successful. An accurate determination of success is critical. The check for success primarily involves ensuring that the number of records output is roughly the same as the number of records input. Hadoop jobs are generally dealing with bulk real world data, which is never 100% clean, so a small error rate is generally acceptable. Reporter.incrCounter( "Input", "Exception", 1 );.

Is the same as "any", whereas "T" means "a specific type". So, compare these interfaces:. When to use which one. Boolean t = true;.

Thursday, December 11, 2008. How not to implement Comparable. I have already blogged about the danger of numeric overflows. I recently came across this example in Java course materials (! Public class Foo implements Comparable Foo {. Private int number;. Public int compareTo(Foo o) {. If (this = o) return 0;. Return number - o.number;. How do you think Integer.MAX VALUE compares to negative numbers? Public class Foo implements Comparable Foo {. Private long id;. Public int compareTo(Foo o) {. I wonder, i...
