cannot convert from Class<capture#1-of ?> to Class<?>[]

marcel ethan272104-Nov-2014

What does it mean, the following error message:

Type mismatch: cannot convert from Class<capture#1-of ?> to Class<?>[]

The code is following:

Class<?>[] encoderClass;Class<?>[] encoderClasses =newClass<?>[]{Encoder1.class,Encoder2.class,Encoder3.class};for(int i=0; i<encoderClasses.length;++i){ encoderClass = encoderClasses[i];// <------ error is here}

You're attempting to assign a single class element to a class array (different types as per the error message). Instead, assign each individual element in the for loop

encoderClass[i]= encoderClasses[i];

ensuring that the array is initialized to avoid NPE in the assignment

Class<?>[] encoderClass =newClass<?>[3];

For simplicity you could replace the entire loop with

encoderClass =Arrays.copyOf(encoderClasses, encoderClasses.length);
