That refers to any symbol used to indicate some calculation. Here are some examples:+, -, *, / (for addition, subtraction, multiplication, division)
++, -- (to add or subtract one)
(or), && (and)
The different types of operators in Java are:Assignment OperatorsRelational OperatorsArithmetic OperatorsLogical Operators
Take a look at the 1st link below from Sun Microsystems (creator of Java), it will list most of the Java operators with an explanation. The 2nd link provides a more in-depth description of each type of operator.
An operator is a symbol that does something in Java. for ex: "+" is an arithmetic operator that adds two numbers. ">" is a logical operator that checks if one number is greater than the other. There are many different types of operators in Java like Arithmetic, Logical, Relational and Assignment operators

They are very similar,but when we do logic operators there are still some differences.In c or c plus plus ,logic true can be expressed as'true' or '0',but in java,true is just 'true'.If you gave a zero,it will treat it as type of integer ,and so as false.
Though Java, unlike other languages, does not allow you to directly access the core, memory addresses and system variables, it does have binary operators, such as the shifters >>, <<, and the bitwise operators, |, &, ^. Using these operators, ALL calculations in the computer can be done, even your complicated trig functions. Though options are limited in Java, it does provide a simulated access to low level operations. The bitwise operators are in the link below. Look at the link below to see how the computer really does math.
"The following" doesn't make sense if you don't include a list. You can find a list of Java operators, including their precendence, at http://docs.oracle.com/javase/tutorial/java/nutsandbolts/operators.html. Or search for [java operator precedence] for additional places that explain this topic.
Postfix expressions are expressions where the operator is at the end of the expression. These include the "++" (increment) and "--" (decrement) operators. Most Java expressions use in-fix notation (e.g. "a + b") but the increment and decrement operators can be postfix ("e.g. "a++" to increment variable a) or even prefix (e.g. "++a").

Logical Operators are those that are used for doing logical operations. There are a total of 6 logical operators (&, |, ^, !, &&, and ‖) Of the six logical operators listed above, three of them (&, |, and ^) can also be used as "bitwise" operators. There are two non-short-circuit logical operators. • & non-short-circuit AND • | non-short-circuit OR There are two short-circuit logical operators • && short-circuit AND • short-circuit OR
There is 48 reserved keywords currently defined in the java language. These keywords, combined with the syntax of the operators and separators,form the definition of the java language. these keywords can't be used as names for a variable,class or method. (chandramohan singh)
It depends on the operator. Some have right-to-left associativity, some are left-to-right, some have no associativity.
