Can we write Java programmes in note pad ?

Answer 1

Yes, we can! But notepad isn't actually a compiler, so it needs to be compiled through the command line.

Answer 2

Yes you can. Just remember to save it as a file with .java extension and its name should be the same as the name of the class. So if your program has a only one class named MainClass your java file should be saved as MainClass.java. After that you can compile it with the command >>javac MainClass.java
And after compilation you can run it with the command >> java MainClass

Answer 3

yes
