An operator is a symbol which helps the user to command the computer to do a certain mathematical or logical manipulations. Operators are used in Java language program to operate on data and variables. Java has a rich set of operators which can be classified as

Conditional operator (?:) is the only ternary operator available in Java which operates on three operands. The symbol "?" placed between the first and the second operand , and " : " is inserted between the second and third operand. The first operand (or expression) must be a boolean . The conditional operator together with operands form a conditional expression which takes the following form.

Logical operators are used to combine one or more relational expressions that results in formation of complex expressions known as logical expressions. Like relational operators, the logical operators evaluate the result of logical expression in terms of Boolean values that can only be true or false according to the result of the logical expression.

The left-shift, right-shift, and zero-fill-right-shift operators <<, >>, and >>> shift the individual bits of an integer by a specified integer amount.

The assignment operator (=) is the most commonly used binary operator in Java. It evaluates the operand on the tight hand side and then assigns the resulting value to a variable on the left hand side. The right operand can be a variable, constant, function call or expression. The type of right operand must be type compatible with the left operand. The general form of representing assignment operator is

The bitwise complement operator (~), which perform a bitwise negation of an integer value. Bitwise negation means that each bit in the number is toggled. In other words, all the binary 0s become 1s and all the binary 1s become 0s.

Relational operators also known as comparison operators are used to check the relation between two operands. In other words, the operators used to make comparisons between two operands are called relational operators. Relational operators are binary operators and hence require two operands. The result of a relational operation is a Boolean value that can only be true or false according to the result of the comparison.

The conversion of a data type which is carried out automatically by the compiler without programmer intervention is called the implicit type conversion. When two variables of different data types are involved in the same expression, the Java compiler uses built-in library functions to trans- form the variables to common data type before evaluating the expression. To decide which variable's data type is to be converted, the Java compiler follows certain rules and converts the lower data type to that of a higher data type. This is known as widening a type.
