When I try to print some XML from a web service call using System.out.println() , only a portion of it is actually printed in the console. The XML string that I am trying to print is huge.

问题 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?

class test{ public static void main(String args[]){ int a = 011; System.out.println(a); } } Why I am getting 9 as output instead of 011 ? How can I get 011 as output? The JLS 3.10.1 describes 4 ways to define integers. An integer literal may be expressed in decimal (base 10), hexadecimal (base 16), octal (base 8), or binary (base 2). An octal numeral consists of a digit 0 followed by one or more of the digits 0 through 7 ... A decimal numeral is either the single digit 0, representing the integer zero, or consists of an digit from 1 to 9 optionally followed by one or more digits from 0 to 9 ..

Kotlin doesn't see Java Lombok accessors?

由 回眸只為那壹抹淺笑 提交于 2019-11-26 18:13:48
问题 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

How do I print output without a trailing newline in Rust?

由 徘徊边缘 提交于 2019-11-26 16:58:44
问题 The macro println! in Rust always leaves a newline character at the end of each output. For example println!("Enter the number : "); io::stdin().read_line(&mut num); gives the output Enter the number : 56 I don't want the user's input 56 to be on a new line. How do I do this? 回答1: You can use the print! macro instead. print!("Enter the number : "); io::stdin().read_line(&mut num); Beware: Note that stdout is frequently line-buffered by default so it may be necessary to use io::stdout().flush(

Capturing contents of standard output in Java

由 爷，独闯天下 提交于 2019-11-26 16:17:50
问题 I am invoking a function that is printing some string in my console/standard output. I need to capture this string. I cannot modify the function that is doing the printing, nor change runtime behavior through inheritance. I am unable to find any pre-defined methods that will allow me to do this. Does the JVM store a buffer of printed contents? Does anyone know of a Java method that will aid me? 回答1: You could temporarily replace System.err or System.out with a stream that writes to string

How to create a println/print method for a custom class

由 我只是一个虾纸丫 提交于 2019-11-26 14:37:38
问题 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

问题 I\'ve been playing around with Swift, and just came across an issue.

I tried escaping it with \\ but it wasn\'t the right way. Appreciate any help. 回答1: Xcode 7
