(1) 加减运算符 +,-.例如 2+39,908.98-23等.
加减运算符是双目运算符,即连接两个操作元的运算符.加减运算符的结合方向是从左到右.例如: 2+3-8,先计算2+3,然后再将得到的结果减8.加减运算符的操作元是整型或浮点型数据,加减运算符的优先级是4级.
(2) 乘,除和求余运算符 *,/, .例如 2*39 908.98/23等.
*,/, 运算符是双目运算符,即连接两个操作元的运算符.*,/, 运算符的结合方向是从左到右,例如 2*3/8,先计算2*3,然后再将得到的结果除以8.乘除运算符的操作元是整型或浮点型数据.*,/, 运算符的优先级是3级.
用算术符号和括号连接起来的符合java语法规则的式子,如x+2*y-30+3*(y+5).-Subtraction of (1) The operators+,- example 2+39,908.98-23, and so on.
The subtraction operator is the operator of the eyes, that is to connect the two operations of the operator. Combination of addition and subtraction operator direction is from left to right: 2+3-8, first calculate 2+3, and then The results obtained minus 8 plus or minus operator operating an integer or floating point data, the subtraction operator priority is 4.
(2) x, and the remainder operator*, /, 2* 39 908.98/23.
*, /, Operator is a binary operator symbol, that is to connect the two operand operator,*, /, operator binding direction is from left to right, for example, 2* 3/8, the first calculation of 2* 3, and then get the results divided by 8. operations multiplication and division operator is the integer or floating point data* / operator priority is 3.
Formula of arithmetic symbols and parentheses to connect java syntax rules, such as x+2* y-30+3* (y+5),
