In Java there existing basic datatypes (like in C/C++):
int, long, float, double, boolean, byte, char

And there existing object-datatypes of it (line in .NET), which are little different in use:
Integer, Long, Float, Double, Boolean, Byte, Character

Jabaco using only the basic data types.
Jabacos Integer is the Java int.
Jabacos Long is the Java long.
Jabacos Single is the Java float.
Jabacos Double is the Java double.
Jabacos Boolean is the Java boolean.
Jabacos Byte is the Java byte.
Jabacos Char is the Java char.

From the object representations only Float can be used.

In Java mostly the basic data types are used. But there existing other compiler (I think Scala is one), which only handles with the object representations.

The problem is now, that there is no possibility to access a Java method from Javaco, which used a oject representation:

public static void myMethod (Integer myInt) {
System.out.println(myInt)
}
