パブリックタイプfactorytestは、それ自身のファイルで定義する必要があります

Question

私の下のプログラムで私は2つのパブリッククラスを使用していますが、これに対して私はエラーを取得せず、出力を得ました。私は混乱しているので、別のプログラムのために同時に私はエラーを得た。

#1 - got output 
    public class factory1 { 
     @Test 
     public void simpleTest() { 
      System.out.println("Simple Test Method."); 
     } 
     public class SimpleTestFactory 
     { 
      @Factory 
      public Object[] factoryMethod() { 
       return new Object[] { new factory1(), new factory1() }; 
      } 
     } 
    } 



For below program i got error: please be help on this 

#2 - got error 
    public class factory2 { 
       private int param; 
       public factory2(int param) { 
       this.param = param; 
      } 
       @Test 
      public void testMethodOne() { 
       int opValue = param + 1; 
       System.out.println("Test method one output: " + opValue); 
      } 
    public class factorytest // got error here 
     { 
      @Factory 
      public Object[] factoryMethod() { 
       return new Object[] { new factory2(0), new factory2(1) }; 
      } 
     } 

Answer 1

I am sorry i missed it i am while posting. Actually where i want to close factory2 class file. i tried in 2 terms but for both i got error. Kindly help on this. 

for below one i am getting an error is **Can't invoke public java.lang.Object[] factory.factory2$SimpleTestFactory.factoryMethod(): either make it static or add a no-args constructor to your class.** 

public class factory2 { 
      private int param; 
      public factory2(int param) { 
      this.param = param; 
     } 
      @Test 
      public void testMethodOne() { 
      int opValue = param + 1; 
      System.out.println("Test method one output: " + opValue); 
     } 
      @Test 
      public void testMethodTwo() { 
      int opValue = param + 2; 
      System.out.println("Test method two output: " + opValue); 
     } 

public class SimpleTestFactory 
{ 
    @Factory 
    public Object[] factoryMethod() { 
     return new Object[] { new factory2(1), new factory2(2) }; 
    } 
} 
} 

For my another try i am getting error like **The factory method class factory.testfactory.factoryMethod() threw an exception**. 

public class factory2 { 
      private int param; 
      public factory2(int param) { 
      this.param = param; 
     } 
      @Test 
      public void testMethodOne() { 
      int opValue = param + 1; 
      System.out.println("Test method one output: " + opValue); 
     } 
      @Test 
      public void testMethodTwo() { 
      int opValue = param + 2; 
      System.out.println("Test method two output: " + opValue); 
     } 
} 
class testfactory 
{ 
    @Factory 
    public Object[] factoryMethod() { 
     return new Object[] { new factory2(1), new factory2(2) }; 
    } 
}
