Is there a difference between concatenating strings with '' and ""?
For example, what is the difference between:
String s = "hello" + "/" + "world";
and
String s = "hello" + '/' + "world";

Solution. The / operator is used for division whereas % operator is used to find the remainder.
& is a bitwise operator and compares each operand bitwise. It is a binary AND Operator and copies a bit to the result if it exists in both operands. (A & B) will give 12 which is 0000 1100. Whereas && is a logical AND operator and operates on boolean operands.
Differences between | and || operators in Java| is a bitwise operator and compares each operands bitwise. It is a binary OR Operator and copies a bit to the result it exists in either operands. (A | B) will give 61 which is 0011 1101. Whereas || is a logical OR operator and operates on boolean operands.
In simple words >>> always shifts a zero into the leftmost position whereas >> shifts based on sign of the number i.e. 1 for negative number and 0 for positive number. For example try with negative as well as positive numbers.
Literals enclosed in double quotes, e.g. "foo", are strings, whereas single-quoted literals, e.g. 'c', are chars. In terms of concatenation behaviour, there'll be no discernible difference.
Nevertheless, it's worth remembering that strings and chars aren't interchangeable in all scenarios, and you can't have a single-quoted string made up of multiple characters.
