J-- is basically a non-OOP version of Java. It is compiled into Java code and is run like a normal Java program, though you can not create new classes. There are plenty of classes available for you to use, including integers, strings, and every other Java class. J-- automatically imports: java.lang.*, java.util.*, java.math.*
. It was made in July, 2015, by User:Phase.
Keywords
All J-- code is put into a class called J
. There are various keywords that are changed into real Java code:
main
->public static void main(String[]a)
fn
->public static
str
->String
dub
->double
fpn
->float
vd
->void
echo
->System.out.println
^^
->!=
nw
->new
map
->HashMap
Built in functions
Here's a copy of some built in functions:
add("public static int fac(int n){int f=1;for(int i=1;i<=n;i++){f*=i;}return f;}"); //factorial function add("public static final double GR = (1+Math.sqrt(5))/2;") //golden ratio used for other functions add("public static int fibo(int n){" + "return (Math.pow(GR,n) - Math.pow(-GR, -n))/Math.sqrt(5);}"); //get nth fibonacci number
Examples
Hello World
main{echo("Hello World");}
Cat
main{ echo(input()); }
Fibonacci sequence
main{ for(int i=0;i<10;i++){ echo(fibo(i)); } }
Factorial
main{ echo(factorial(5)); }
