#2.1 Java Tutorial | Variable in Java

In this lecture we are discussing
1) what is variable?
2) When you say about software then does means in term of data?
3)Comparison of variable with container
4) How to store different data types ?
#1
Let us assume we have different size of container
int this container we can store different type of object.
Hence we can compare our variable as container.
#2
When you simply say about software than software is all about data
when you deal with software means data and you build a software to store data.
#3
Suppose we have different cover - headphone cover , mobile cover, laptop cover
so you can store your headphone in any of this cover
but if you want to store mobile then you can store only in two cover.
Same for variable they are some restriction to store which type of data can
store in particular type of variable
#4
for store a different data we have different type of data
for number we have integer , float, double, long, short, byte .
for character char and for boolean we have boolean.

Sir there are so many playlists like OOP, java beginners from where i have to start and where i have to end to learn complete JAVA

[SmartProgramming]

Your way of explanation is awesome sir thank you....

With all due respect sir Integer is 2 byte in 32 bit architecture not in C, in C Integer is also 4 byte if architecture is 64 bit. 'Sizeof' of data types depend on architecture not on languages. And thank you so much for video tutorials, it's really great!
