# Summary of Operators

The following quick reference summarizes the operators supported by the Java programming language.

## Simple Assignment Operator

    =       Simple assignment operator

## Arithmetic Operators

    +       Additive operator (also used
            for String concatenation)
    -       Subtraction operator
    *       Multiplication operator
    /       Division operator
    %       Remainder operator

## Unary Operators

    +       Unary plus operator; indicates
            positive value (numbers are
            positive without this, however)
    -       Unary minus operator; negates
            an expression
    ++      Increment operator; increments
            a value by 1
    --      Decrement operator; decrements
            a value by 1
    !       Logical complement operator;
            inverts the value of a boolean

## Equality and Relational Operators

    ==      Equal to
    !=      Not equal to
    >       Greater than
    >=      Greater than or equal to
    <       Less than
    <=      Less than or equal to

## Conditional Operators

    &&      Conditional-AND
    ||      Conditional-OR
    ?:      Ternary (shorthand for
            if-then-else statement)

## Type Comparison Operator

    instanceof      Compares an object to
                    a specified type

## Bitwise and Bit Shift Operators

    ~       Unary bitwise complement
    <<      Signed left shift
    >>      Signed right shift
    >>>     Unsigned right shift
    &       Bitwise AND
    ^       Bitwise exclusive OR
    |       Bitwise inclusive OR
