Cannot create a generic array in Java

Question

I try to create a generic array but I'm taking the error of the title.

 ByteConverter<Product> byteconverter = new ByteConverter<Product>();
 //into an inner class I have to declare a final field 
 final ByteConverter<Product>[] byteconverter2 = {byteconverter};

So, I searched at the Stackoverflow for a possible solution. I found something similar here: Cannot create an array of LinkedLists in Java...? , so I canged my code to the following:

 final ByteConverter<Product>[] byteconverter2 = {(ByteConverter<Product>[])byteconverter};

but I still take the same error. I can't understand why..Any help please?

• Rohit Jain: What error are you getting?
• Georgian: Read through stackoverflow.com/questions/529085/…. You should find your answer.
• Nick Robertson: @Rohit Jain: Cannot create a generic array of ByteConverter<Product>

Answer 1

final ByteConverter<Product>[] byteconverter2 = 
 new ByteConverter[]
 {
 byteconverter 
 };

this works well

• Rohit Jain: You don't need to give type on RHS, while initializing array at the time of declaration.
• Nandkumar Tekale: and it is applicable for java 7 only

Answer 2

This compiles, though with a warning

 ByteConverter<Product> byteconverter = new ByteConverter<Product>();
 ByteConverter<Product>[] byteconverter2 = new ByteConverter[] { byteconverter };
