Ideas in this flowchart

  • Order of precedence of Java operators
  • Precedence determines the order in which operators in one statement are evaluated.
  • Example: (b*b < 4*a*c || a == 0 || args.length != 4)
  • The table summarizes the precedence levels and associativity of the operators discussed.
  • Highest: ++ and --, postfix increment operators, left-to-right
  • - and !, unary negation and logical not, right-to-left
  • * , / , %, arithmetic multiplication, division, and remainder, left-to-right
  • + and -, addition and subtraction, left-to-right
  • <, <=, >, >=, comparison operators, left-to-right
  • == and !=, equality and inequality operators, left-to-right
  • &&, logical And, left-to-right
  • ||, logical Or, left-to-right
  • Lowest: =, +=, -=, *=, /=, assignment and compound assignment operators, right-to-left
  • Operators on the same level have equivalent precedence and follow the specified associativity.
  • The list is not an exhaustive list of Java operators.

"27.1.1. Order of Precedence\n\nAt this point it is worth summarizing the order of precedence of all the operators that we’ve seen so far including assignment, arithmetic, comparison, and logical. Since all of these operators could be used in one statement, for example, (b*b < 4*a*c || a == 0 || args.length != 4) It is important to understand the order in which each one gets evaluated. Table 27.3 summarizes the order of precedence for the operators seen so far. This is not an exhaustive list of Java operators.\n\nOperator(s) | Associativity | Notes\n\nHighest | |\n\n++ , -- | left-to-right | postfix increment operators\n\n- , ! | right-to-left | unary negation operator, logical not\n\n* , / , % | left-to-right |\n\n+ , - | left-to-right | addition, subtraction\n\n< , <= , > , >= | left-to-right | comparison\n\n== , != | left-to-right | equality, inequality\n\n&& | left-to-right | logical And\n\n|| | left-to-right | logical Or\n\nLowest | |\n\n= , += , -= , *= , /= | right-to-left | assignment and compound assignment operators\n\nTable 27.3.: Operator Order of Precedence in Java. Operators on the same level have equivalent order and are performed in the associative order specified."
