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(){...})
test
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
