Java Operators

In this chapter you will learn:

1. What are the four groups of Java operators
2. What is the Precedence for Java Operators

Four groups of Java operators

Java operators can be divided into the following four groups:

• arithmetic,
• bitwise,
• relational,
• logical.

Operators are classified as prefix, postfix, and infix.

• A prefix operator is a unary operator that precedes its operand, for example -6.
• A postfix operator is a unary operator that trails its operand, for example x++.
• An infix operator is a binary or ternary operator that is placed between the binary operator's two or the ternary operator's three operands, for example x + 5.

Java Operator Precedence

The following table shows the order of precedence for Java operators, from highest to lowest.

1. () [] . (Highest)
2. ++ - - ~ !
3. * / %
4. + -
5. > >>> << ]]>
6. >= < <= ]]>
7. == !=
9. ^
10. |
12. ||
13. ?:
14. = op= (Lowest)
