// Java code:

package test;

class Test {
	public Test() {
	}

	public String hello() {
		return "Hello, world!";
	}
}

// Generated Delphi interface:

type
  Itest_Test = interface(Ijava_lang_Object)
    function hello: string;
  end;

  Ttest_Test = class(Tjava_lang_Object, Itest_Test)
  public
    constructor Create(JavaObject: JObject); overload;
    constructor Create; overload;
  end;

  Ttest_TestClass = class(Tjava_lang_ObjectClass)
  public
    property _initID: JMethodID read F_initID;
    property helloID: JMethodID read FhelloID;
  end;

function Get_test_TestClass: Ttest_TestClass;

// Usage:

CreateJavaVM;
ShowMessage(Ttest_Test.Create.hello);
