oop - Is it necessary to create a Java class everytime? -


i starting learn java programming language , little confused.

i create simple program adding 2 numbers or calculate sum of n numbers. can in c or python easily, in java, have create class program , create main class , call program it.

i use both netbeans , intellij.

can create program directly way in other languages? mean concept of class necessary in java?
