The following tables summarize the semantic similarities between Java and VjO.

Semantic Java VJET VJO
Declare a Namespace package vjo.x.y 
vjo.ctype("vjo.x.y.Z") // where Z is the name of a class.
Import a Class import vjo.utils.X 
.needs("vjo.utils.X")

Type Definitions and Manipulation

Semantic Java VJET VJO
Define a Class 
class X{}
 
vjo.ctype("<namespace>.X")
Define an Interface 
interface Y{}
 
vjo.itype("<namespace>.Y")
Define an Enum 
enum E{}
 
vjo.etype("<namespace>.E")
Define an Abstract Class 
abstract class Z{}
 
//> abstract
vjo.ctype("<namespace>.Z")
Define an Inner Class 
class X{}
 
X : vjo.ctype()
Modify a Type 
final class R{};
 
//> final
vjo.ctype("vjo.R")
Define a Constructor 
D(){}
 
constructs: function(){}
Overload a Constructor 
D(int arg){}
D(String arg){}
 
//>public void constructs(int arg)
//>public void constructs(String arg)
constructs:function(arg){}
Call a Super Constructor 
super()
 
this.base()
Call a Super Constructor with Arguments 
super(arg)
 
this.base(arg)
Call a Super Method 
super.doIt()
 
this.base.doIt()
Extend a Class 
class X extends Y
 
vjo.ctype("<namespace>.X")
.inherits("<namespace>.Y")
Implement an Interface 
class X implements Y
 
vjo.ctype("<namespace>.X")
.satisfies("<namespace>.Y")
Implement an Instance Method 
void setName(String name)
 
.protos({
setName: function(String name)
Implement a Static Method 
static void setName(String name)
 
.props({
setName: function(String name)
})
Implement a Static Initializer 
{// static initialization here
static{...}
 
// static initialization here
.inits(function(){...})


Declarations

To Declare Java VJET VJO
Enum Constants 
public enum Days {
MON,TUE,WED,THU,FRI,SAT,SUN
}
 
vjo.etype('<namespace>.Days')
.values('MON,TUE,WED,THU,FRI,SAT,SUN')
Argument Types 
void setName(String name){}
 
//> void setName(String name)
setName : function(name){}
Method Scope 
public void setName(String name){}
 
//>public void setName(String name)
setName : function(name){}
Return Type 
public X getIt(){}
 
//> public X getIt()
getIt : function(){}
Overloaded Method 
public X getIt(String x)
public X getIt(int x)
 
//>public X getIt(String x)
//>public X getIt(int x)
getIt:function(x) {}
Method with Variable Arguments 
public X getIt(String... x)
 
//>public X getIt(String... x)
getIt:function(x) {}
Local Variable 
int x = 10;
String s = "hello";
final boolean ok = false;
 
var x = 10; //< int
var s = 'hello'; //< String
var ok = false; //< final boolean
