Appendix B. Java Operator Summary
The Java operators are listed in groups of decreasing precedence in the table below. The horizontal lines in the table indicate a change in operator precedence. For example, z = x - y; means z = (x - y); because = has lower precedence than -.
The prefix unary operators, conditional operator, and the assignment operators associate right-to-left. All other operators associate left-to-right.
