Java是一種高級(jí)編程語言，使用操作符和運(yùn)算符來處理變量和數(shù)值。Java中的操作符和運(yùn)算符包括算術(shù)運(yùn)算符、位運(yùn)算符、關(guān)系運(yùn)算符、邏輯運(yùn)算符和條件運(yùn)算符。

//算術(shù)運(yùn)算符
int a = 10;
int b = 20;
int c = a + b;  //加法
int d = a - b;  //減法
int e = a * b;  //乘法
int f = b / a;  //除法
int g = b % a;  //取模
//位運(yùn)算符
int h = 3;      // 二進(jìn)制為00000011
int i = 6;      // 二進(jìn)制為00000110
int j = h & i;  //按位與 00000010
int k = h | i;  //按位或 00000111
int l = h ^ i;  //按位異或 00000101
int m = ~h;     //按位非  11111100
int n = i<< 2; //左移兩位 00011000
int o = i >>2; //右移兩位 00000001
//關(guān)系運(yùn)算符
int p = 5;
int q = 10;
boolean r = p == q;  //等于
boolean s = p != q;  //不等于
boolean t = p >q;   //大于
boolean u = p< q;   //小于
boolean v = p >= q;  //大于等于
boolean w = p<= q;  //小于等于
//邏輯運(yùn)算符
boolean x = true;
boolean y = false;
boolean z = x && y;  //與
boolean a1 = x || y; //或
boolean a2 = !x;     //非
//條件運(yùn)算符
int max = (p >q) ? p : q;

以上就是Java中常用的操作符和運(yùn)算符，熟練掌握這些運(yùn)算符可以提高編程效率和代碼質(zhì)量。
