Another solution would be to convert InputStream to byte array, then iterate over the array as many time as you need. You can find several solutions in this post Convert InputStream to byte array in Java using 3rd party libs or not. Caution, if the read ...
How is null + true a string?
...1) That means that this will fail to compile:
// Error: Cannot implicitly convert type 'string' to 'Foo'
Foo f = null + true;
Other second-operand types will use some other operators, of course:
var x = null + 0; // x is Nullable<int>
var y = null + 0L; // y is Nullable<long>
