println

Using Kotlin 1.0.0 release (compiling in IntelliJ 15). println(myPojoInstance.foo) When it tries to compile code (in IntelliJ or Gradle) that references Lombok based POJOs it gives the error "Cannot access 'foo': it is 'private' in "MyPojo". Which is true, they're all private and my object has @Value @Builder for lombok annotations. I've tried specifically calling getFoo(), but it says "unresolved reference for getFoo". There's perhaps some trick to make Kotlin aware of how to handle the lombok annotations? Generally, no, it doesn't. The reason of that behavior is that Lombok is an annotation

I have following code : System.out.println(" | 1 2 3 4 5 6 7 8 9"); System.out.println("----------------------------"); System.out.println(""); I use println to create a new line. Is it possible to do the same using \n or \r? I tried to add \n to the second println statment and continue printing with the print method but \n does not create a new line. any ideas? String newLine = System.getProperty("line.separator");//This will retrieve line separator dependent on OS. System.out.println("line 1" + newLine + "line2"); System.out.println("hello"+"\n"+"world"); vstoyanov Your best shot would be

What does my own made class need to support in order for println() to print it? For example, I have: public class A { ... } What methods should class A have to make this code work? Maybe something like this: public static void main() { A a = new A(); System.out.println(a); } I have a guess that the toString() method must be overloaded. Am I right? Is this enough? You can print any Object using System.out.println(Object) . This overloaded version of println will print out toString representation of your object. If you want to customize what will be printed out, you must override the Object

I'm working in Java on a project that requires me to make a few 'container' classes, if you will. Here is a simple version of one: public class Pair{ Object KEY; Object VALUE; public Pair(Object k, Object v) { KEY = k; VALUE = v; } public Object getKey() { return KEY; } public Object getValue() { return VALUE; } } (Please note, this is severely simplified and I am using proper set/get methods in the final version.) My question is this: When calling the println method with an ArrayList as the parameter, for example: ArrayList<String> arr = new ArrayList<String>(); arr.add("one"); arr.add("two")

In Rust, this works: fn main() { let a = [0; 32]; println!("{:?}", a); } but this doesn't: fn main() { let a = [0; 33]; println!("{:?}", a); } Compile error: error[E0277]: the trait bound `[{integer}; 33]: std::fmt::Debug` is not satisfied --> src/main.rs:3:22 | 3 | println!("{:?}", a); | ^ the trait `std::fmt::Debug` is not implemented for `[{integer}; 33]` | = note: `[{integer}; 33]` cannot be formatted using `:?`; if it is defined in your crate, add `#[derive(Debug)]` or manually implement it = note: required by `std::fmt::Debug::fmt` I assume that the std::fmt::Debug function somehow

I've been playing around with Swift, and just came across an issue. I have the following Dictionary in: var locations:Dictionary<String,CLLocationCoordinate2D> = ["current":CLLocationCoordinate2D(latitude: lat, longitude: lng) ]; println("current locaition is \(locations["current"])") but the compiler is complaining about double quotes around current which represent the a key in my dictionary. I tried escaping it with \ but it wasn't the right way. Appreciate any help. Xcode 7.1+ Since Xcode 7.1 beta 2, we can now use quotations within string literals. From the release notes: Expressions
