You should first compile your class then run the the compiled class and not the sources. So from command line:
d:
cd programos/xampp/htdocs/im/OpenCV/src/stitching
javac Main.java
The above command will tell the java compiler to compile the sources of the Main class and generate a .class in bytecode which can be passed to the java process to be run:
java Main

You have to go one dir up cd .. and than java stitching.Main

Still nothing, "Error: Could not find or locate main class Main" running "java -cp Main.class Main"

@Justinas Sorry my fault. I have corrected my answer

@Justinas: the classpath (
-cp) argument should contain the folders or JARs that contain the classes, not the classes themselves. From the src folder, try java -cp . stitching.Main.Because you declared your Main class to be in package stitching, what you should need to do is actually navigate to the folder above the root package (in the bin directory), then execute java stitching/Main
