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 higher precedence than addition and subtraction. Precedence rules can be overridden by explicit parentheses....
In Java, the precedence of * is higher than that of -. Hence, the multiplication is performed before subtraction, and the value of myInt will be 4. Operator Precedence Table The table below lists the precedence of operators in Java; higher it appears in the table, the higher its precedence...
优先级(precedence):操作符的优先级指,在没有括号的情况下,表达式中多个操作符的作用顺序。 前置条件(precondition):在程序的执行过程中,为了让程序正确运行,前置条件必须判定为 true。子程序的前置条件是指,为了让子程序正确运行必须满足的前置条件。子程序的前置条件通常是对传入的子程序的实参值进行的限制。 优先级...
