"Hello, World" by appending strings in a variety of languages. Just thought it would be fun to compare syntaxes.

Hello, Worlds!

//Objective-C
	NSMutableString *str = [[NSMutableString alloc] initWithFormat:@"Hello "]; //NSMutableString *str = @"Hello,";
	str = [str stringByAppendingString:@" world!"];
	
	NSLog(@"%@", str); //Output: Hello, world!


//Java
    String newString = "Hello, ";
    String secondString = " world!";
    newString += newString + oldString;
    
    System.out.println(bothStrings); //Output: Hello, world!


//Swift
    var str = "Hello,"
    str += " world!"
    
    println(str); //Output: Hello, World!
