Table A.2.4 Boolean operators. x and y are Boolean types. x and y can be
expressions that result in a Boolean value. Result is a Boolean true or
false value.

Operator Name Description

Conditional
AND

If both x and y are true, result is true.
If either x or y are false, the result is false
If x is false, y is not evaluated.

x&&y

Boolean
AND

If both x and y are true, the result is true.
If either x or y are false, the result is false
Both x and y are evaluated before the test.

x&y

x || y

Conditional
OR

If either x or y are true, the result is true.
If x is true, y is not evaluated.

x | y

Boolean
OR

If either x or y are true, the result is true.
Both x and y are evaluated before the test.

Boolean
NOT

If x is true, the result is false.
If x is false, the result is true.

!x

Boolean
XOR

If x is true and y is false, the result is true.
If x is false and y is true, the result is true.
Otherwise, the result is false.
Both x and y are evaluated before the test.

x ^ y

Table A.2.5 Comparison operators. x and y are numeric or char types only
except for “== ” and “ ! = ” operators, which can also compare references. If
mixed types, then the narrower type converted to wider type. Returned value is
Boolean true or false .

Operator Description

Is x less than y?

x < y

Is x less than or equal to y?

x <= y

Is x greater than y?

x > y

Is x greater than or equal to y?

x >= y

Is x equal to y?

x == y

Is x not equal to y?

x!= y
