How to read a file in AWS Lambda Function written in Java ?

Question

I have written an AWS Lambda Handler as below :

package com.lambda;
import com.amazonaws.services.lambda.runtime.Context;
import com.amazonaws.services.lambda.r

If the file is located under resources folder, you can use it directly in lambda by using something like the following code:

final BufferedReader br = new BufferedReader(new FileReader("/flows/cancellation/MessageArray.json"));

I wanted to read a json file, you can have different use case, but the code works.
