Syntax: Array.+() Parameter: Arrays for performing the concatenation operation. Return: New arrays by combining two arrays. Example #1 : Ruby # Ruby code for +() method # showing concatenate operation # declaring array a = [18, 22, 33, 4, 5, 6] # declaring array b = [5, 4, 22, 1, 88, 9] # declaring array c = [18, 22, 33, 40, 50, 6] # combining arrays puts "combination of a and b : #{a + b}\n\n" # combining arrays puts "combination of a and c : #{a + c}\n\n" # combining arrays puts "combination of b and c : #{b + c}\n\n" Output : combination of a and b : [18, 22, 33, 4, 5, 6, 5, 4, 22, 1, 88, 9] combination of a and c : [18, 22, 33, 4, 5, 6, 18, 22, 33, 40, 50, 6] combination of b and c : [5, 4, 22, 1, 88, 9, 18, 22, 33, 40, 50, 6] Example #2 : Ruby # Ruby code for +() method # showing concatenate operation # declaring array a = ["abc", "xyz", "dog"] # declaring array b = ["cow", "cat", "dog"] # declaring array c = ["cat", "1", "dog"] # combining arrays puts "combination of a and b : #{a + b}\n\n" # combining arrays puts "combination of a and c : #{a + c}\n\n" # combining arrays puts "combination of b and c : #{b + c}\n\n" Output : combination of a and b : ["abc", "xyz", "dog", "cow", "cat", "dog"] combination of a and c : ["abc", "xyz", "dog", "cat", "1", "dog"] combination of b and c : ["cow", "cat", "dog", "cat", "1", "dog"] Create Quiz Comment M mayank5326 Follow 0 Improve M mayank5326 Follow 0 Improve Article Tags : Ruby Ruby-Methods Ruby Array-class Explore OverviewRuby For Beginners3 min readRuby Programming Language (Introduction)4 min readComparison of Java with Other Programming Languages4 min readSimilarities and Differences between Ruby and C language3 min readSimilarities and Differences between Ruby and C++3 min readEnvironment Setup in Ruby3 min readHow to install Ruby on Linux?2 min readHow to install Ruby on Windows?2 min readInteresting facts about Ruby Programming Language2 min readBasicsRuby | Keywords4 min readRuby | Data Types3 min readRuby Basic Syntax3 min readHello World in Ruby2 min readRuby | Types of Variables4 min readGlobal Variable in Ruby2 min readComments in Ruby2 min readRuby | Ranges4 min readRuby Literals4 min readRuby Directories5 min readRuby | Operators11 min readOperator Precedence in Ruby2 min readOperator Overloading in Ruby5 min readRuby | Pre-define Variables & Constants5 min readRuby | unless Statement and unless Modifier2 min readControl StatementsRuby | Decision Making (if, if-else, if-else-if, ternary) | Set - 13 min readRuby | Loops (for, while, do..while, until)5 min readRuby | Case Statement3 min readRuby | Control Flow Alteration7 min readRuby Break and Next Statement2 min readRuby redo and retry Statement2 min readBEGIN and END Blocks In Ruby2 min readFile Handling in Ruby4 min readMethodsRuby | Methods3 min readMethod Visibility in Ruby3 min readRecursion in Ruby4 min readRuby Hook Methods5 min readRuby | Range Class Methods5 min readThe Initialize Method in Ruby2 min readRuby | Method overriding2 min readRuby Date and Time3 min readOOP ConceptsObject-Oriented Programming in Ruby | Set 19 min readObject Oriented Programming in Ruby | Set-28 min readRuby | Class & Object4 min readPrivate Classes in Ruby3 min readFreezing Objects | Ruby2 min readRuby | Inheritance4 min readPolymorphism in Ruby3 min readRuby | Constructors2 min readRuby | Access Control8 min readRuby | Encapsulation2 min readRuby Mixins3 min readInstance Variables in Ruby3 min readData Abstraction in Ruby3 min readRuby Static Members3 min readExceptionsRuby | Exceptions4 min readRuby | Exception handling6 min readCatch and Throw Exception In Ruby3 min readRaising Exceptions in Ruby4 min readRuby | Exception Handling in Threads | Set - 12 min readRuby | Exception Class and its Methods3 min readRuby RegexRuby | Regular Expressions3 min readRuby Search and Replace2 min readRuby ClassesRuby | Float Class7 min readRuby | Integer Class3 min readRuby | Symbol Class5 min readRuby | Struct Class5 min readRuby | Dir Class and its methods3 min readRuby | MatchData Class4 min readRuby ModuleRuby | Module4 min readRuby | Comparable Module3 min readRuby | Math Module4 min readInclude v/s Extend in Ruby2 min readCollectionsRuby | Arrays4 min readRuby | String Basics5 min readRuby | String Interpolation3 min readRuby | Hashes Basics4 min readRuby | Hash Class12 min readRuby | Blocks6 min read Like
