3. Operators

3.1. Basic arithmetic operators

int a = 1 + 1;
int b = 1 - 1;
int c = 1 * 2;
int d = 2 / 4;
int e = 4 % 3;

3.2. Unary operators

int a = 10;
int b = --a;
int c = a--;
int d = ++a;
int e = a++;

3.3. Compound assignment operators

int a = 10;
a = a + 4;

int b = 10;
b += 4;

int c = 10;
c = c - 4;

int d = 10;
d -= 4;

int e = 10;
e = e * 2;

int f = 10;
f *= 2;

int g = 10;
g = g / 2;

int h = 10;
h /= 2;

3.4. Bitwise operators

var a = 42;
var b = 15;

var q = ~42; // bitwise not
var r = a | b; // bitwise or
var s = a & b; // btiwise and
var t = a ^ b; // bitwise XOR

var a = 1;

var x = a << 1;
var y = a << 2;
var z = a << 3;

var a = 8;

var x = a >> 1;
var y = a >> 2;
var z = a >> 3;

var a = -1;

var x = a >>> 8;
var y = a >>> 16;
var z = a >>> 24;

3.5. Relational operators

var num1 = 4;
var num2 = 2;

var a = num1 == num2;
var b = num1 != num2;
var c = num1 > num2;
var d = num1 < num2;
var e = num1 >= num2;
var f = num1 <= num2;

3.6. Boolean logical operators

var a = false;
var b = false;

var a_or_b = a | b;
var a_and_b = a & b;
var a_xor_b = a ^ b;
var not_a = !a;
var a_short_or_b = a || b;
var a_short_and_b = a && b;
var ternary = a ? true : false;

3.7. Parentheses

var result1 = 4 + 2 * 2;
var result2 = (4 + 2) * 2;
