+# Java Tutorial: Operators, Types of Operators & Expressions in Java
+- An operator is a symbol that the compiler to perform a specific operation on operands.
+- Example :  a + b = c
+- In the above example, 'a' and 'b' are operands on which the '+' operator is applied.
+
+## Types of operators :
+### 1. Arithmetic Operators :
+- Arithmetic operators are used to perform mathematical operations such as addition, division, etc on expressions.
+- Arithmetic operators cannot work with Booleans.
+- % operator can work on floats and doubles.
+- Let x=7 and y=2

+
+### 2. Comparison Operators :
+- As the name suggests, these operators are used to compare two operands.
+- Let x=7 and y=2

+
+### 3. Logical Operators :
+- These operators determine the logic in an expression containing two or more values or variables.
+- Let x = 8 and y =2

+
+### 4. Bitwise Operators :
+- These operators perform the operations on every bit of a number.
+- Let x =2 and y=3. So 2 in binary is 100, and 3 is 011.

+
+## Precedence of operators
+- The operators are applied and evaluated based on precedence. For example, (+, -) has less precedence compared to (*, /). Hence '*' and / are evaluated first.
+- In case we like to change this order, we use parenthesis ()
+
+## Code as Described in the Video
+```
+package com.company;
+
+public class CWH_Ch2_Operators {
+    public static void main(String[] args) {
+        // 1. Arithmetic Operators
+        int a = 4;
+        // int b = 6 % a; // Modulo Operator
+        // 4.8%1.1 --> Returns Decimal Remainder
+
+        // 2. Assignment Operators
+        int b = 9;
+        b *= 3;
+        System.out.println(b);
+
+        // 3. Comparison Operators
+        // System.out.println(64<6);
+
+        // 4. Logical Operators
+        // System.out.println(64>5 && 64>98);
+        System.out.println(64>5 || 64>98);
+
+        // 5. Bitwise Operators
+        System.out.println(2&3);
+        //        10
+        //        11
+        //        ----
+        //        10
+    }
+}
