Table A.2.8 Other operators.

Operator Name Description

Conditional
Operator

The first operand - boolean -isaBoolean variable or
expression.
First this Boolean operand is evaluated. If it is true
then the second operator is evaluated and x is set to
that value.
If the Boolean operator is false , then the third
operand is evaluated and x is set to that value.

x= boolean ?y:x

( primitive type ) Type Cast To assign a value of one primitive numeric type to a

more narrow type, e.g. long to int ,anexplicit cast
operation is required, e.g.

long a = 5;
int b = (int)a;

Table A.2.9 Operator precedence. The larger the number, the higher the precedence.

Notes:

• ( type ) refers to the casting operator.
• “. „ is the object member access operator.
• [] is the array access operator.
• ( args ) indicates the invocation of a method.
• In column 11, the + and -- refer to binary addition and subtraction. Also, the + refers to the string
concatenation operator. In column 14, the + and -- refer to the unary operations +x and -x and specify
the sign of the value.
•|, ^ , and & refer to both the bitwise and Boolean operators.
