01.Java Basics.
Java First Program:
Essential Statements of java Program
To develop, compile, execute and print output on monitor, every java program must has below 3 statements.
1. class block: because only class allows us to define method with logic.
2. main method: because  it is initial point of class logic execution.
3. System.out.println: because in java all kinds of data is printed by using this statement .

 The below programs should compile and execute without errors when we use below main methods.
