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
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....
Conditional:A ? B : C. EvaluateBorC, depending on the result of the evaluation ofA. The precedence of operators highest to lowest, left to right is as follows: [] . ()(used to change the precedence of operators) -(unary)not ! empty ...
Stack<Double> values = new Stack<>();:栈用于存储数值。 Stack<Character> operators = new Stack<>();:栈用于存储运算符。 precedence()方法用于判断运算符优先级。 applyOperator()方法对两个操作数进行相应的运算。 步骤4:输出计算结果 最后,我们可以将计算结果输出给用户。 publicstaticvoidmain(String[]ar...
Java offers an extensive range of operators — so far we have only looked at the most commonly used. In this chapter we are going to look at a much wider range of operators and their precedence. If you are an experienced programmer it is still worthwhile reading this chapter, since Java ...
Operators on the same line have equal precedence. When operators of equal precedence appear in the same expression, a rule must govern which is evaluated first. All binary operators except for the assignment operators are evaluated from left to right; assignment operators are evaluated right to ...
143 int precedence = Operator.getPrority(c); 144 while (!stack.isEmpty() && Operator.getPrority(stack.peek()) >= precedence) { 145 sb.append(SEPARATOR).append(stack.pop()); 146 } 147 stack.push(c); 148 } 149 } 150 } 151 while (!stack.isEmpty()) { ...
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...
