About string operands

Well known data type String is also available on Java.

There are a lot of easy-to-use features on using String data type.
But its little bit complicated on actually using them.

Let me explain by some actual examples.

As you see on the 4th line, if you put the calculating expression in front of the string (which is covered in quotes) and it will automatically return the calculated value of the expression and merge those two strings.

The opposite seems to show the same output, but it doesn't.
See the 5th line and you will see. The following expression 3 + 4 isn't calculated.

~~Didn't know dem~~

Its always good to know new things ;)

About bitwise and bit shift operands

We are getting to know about Java's basics. Java has the bitwise operators. (which all other advanced programming language do either) There are several operands of them. Bitwise operators & opreator Performs an and calculation between data bits ^ opreator Performs an or calculation between data bits | opreator Performs a xor calculation between data bits ~ operator Inverts all data bits Bitshift operators << operator Shifts the bit pattern to the left >> operator Shifts the bit pattern to the right >>> operator Shifts the zero to the leftmost position These are the opreators. which is never used. Even the Java Documentation says these are "less commonly used". So just make sure you 'heard' of these exists. Check out more about these operators here: Official Java Documentation

About loop statements

Well this is a very basic thing. This is about loop statements on a few programming language. First one is the language Java . That can't be easier than that. Second, C++ . Absolutely not a copy of Java one Looks extremely same. On the next, python This is a lot different from other languages. Its mostly because of python's special language syntax, not much different from the logic. And more about python's loop, at the first line, it says for i in range(0, 6): . It seems logically, it should be in range(0, 5) to make it repeat to 5. But in python, range(x, y) counts from x to y + 1, so keep this in mind. And python, doesn't have do {} while () statement. So instead, from this stackoverflow answer , there is a somewhat similar code in python. See the line 10, the while loop is infinite loop and it will run the code print k for the first time of the loop. And then, it checks the statement if k>= 5: and determines whether break the ...
