The Java integration is very rudimentary at this point. It has a few restrictions:

• Supported Java types are int, boolean, String
• Only public static functions and public methods (including the constructor) are imported
• No function overloading
• No variadic functions
• No member access
• No generic types

Java

package de.slashbinbash.muckefuk;

public class TestClass {
    public int value;

    public static int testA(int a, int b) {
        return a + b;
    }

    public TestClass(int value) {
        this.value = value;
    }

    public void printValue() {
        System.out.println(value);
    }
}

Muckefuk

import("de.slashbinbash.muckefuk.TestClass");

# static method call
TestClass.testA(5, 10);  # returns 15

# constructor call
obj = TestClass.new(42);
obj.printValue();        # prints 42

The std.Array and std.Object data structures are also implemented as Java classes that you have to import:

import("std.Object", "std.Array");

# create an object using the constructor concept
obj = Object { name:"Bob", age:42 };

arr = Array { 1, 2, 3, 4 };
