java operator priority

As we explore the operators of the Java programming language, it may be helpful for you to know ahead of time which operators have the highest precedence. The operators in the following table are listed according to precedence order. The closer to the top, Appendix A: Operator Precedence in Java. Java has well-defined rules for specifying the order in which the operators in an expression are evaluated when the expression has several operators. For example, multiplication and division have a higher preceden,Precedence, Operator, Type, Associativity. 15, () [] ·, Parentheses Array subscript. Member selection, Left to Right. 14, ++ --, Unary post-increment. Unary post-decrement, Right to left. 13, ++ -- + - ! ~ ( type ), Unary pre-increment. Unary pre-decremen, The Java || operator (logical or operator) does not evaluate additional arguments if the left operand is true . If you wanted to do that, you can use | (bitwise or operator), although, according to the name, this is a little of a hack. http://docs.oracle,As far as the "Real World" is concerned, it's probably fair to say: enough programmers know that multiplication/division take precedence over addition/subtraction, as is mathematically the convention; hardly any programmers can remember any , See Why is this Java operator precedence being ignored here?. It boils down to the fact that the postfix operator is being evaluated first, but returns the original value of the variable, as designed. So, for the purposes of your operation: (d++ + ++d) P, Operator precedence the way you defined it, while common, is not a universal truth that the Java language should recognize. Therefore no, Java language itself does not have such comparison. It is of course easy to write your own: int precedenceLevel(char, The parentheses just describe how the sub-expressions will be grouped together. Parenthesizing doesn't mean it will be evaluated first. Rather, the rule in java is evaluate each sub-expression strictly from left to right. Always remember that the ord, I was looking at the java specification to see if they defined operator precedence for && and ||. Both are defined as left-associative and no operator precedence is defined. See s. 15.7.3 a bit down from s. 17.7, && s. 15.23, || s. 15.24.,Operator precedence determines the order in which the operators in an expression are evaluated.
