John works as a Programmer for Technostar Inc. He writes the following code using Java.
1. class WrapperClass{
2. public static void main(String[] argv){
3. String str2 = Double.toString(12);
4. String str1 = Double.toHexString(12);
5. System.out.println(str1+str2);
6. }
7. }
What will happen when John attempts to compile and execute the code?
