(2)Logical Operators in Java Operators
Logical operators are used to determine the logic between variables or values:
| Operator | Name | Description | Example |
|---|---|---|---|
| && | Logical and | Returns true if both statements are true | y > 3 && y< 100 |
| || | Logical or | Returns true if one of the statements is true | x > 15 || x < 10 |
| ! | Logical not | Reverse the result, returns false if the result is true | !(x > 5 && x < 20) |
&& Operator

|---|---|
| int x =10; | Declare variable name x with data type int and store 10 inside it. Declare variable name y with data type int and store 5 inside it. |
| if(x>5 && x<15){ | Checking and condition, if x is greater than 5 and less than 15 which is true as x contain 10 which is greater then 5 and less then 15, so here && condition is true. |
| System.out.println("True"); | As && condition is true so here True will be printed on the Screen. |
| System.out.println("False"); | If && condition is false then False will be printed on the Screen. |
|| Operator
| Code | Explanation |
|---|---|
| int x =10; | Declare variable name x with data type int and store 10 inside it. Declare variable name y with data type int and store 5 inside it. |
| if(x>40 || x<5) | Checking logically or condition, if x is greater than 40 or x is less than 5 which is false as x contain 10 which is less than 40 and greater than 5, so here || condition is false. |
| System.out.println("False"); | As || condition is false so here False will be printed on the Screen. |
| System.out.println("True"); | If || condition is true then True will be printed on the Screen. |
! Operator
Explanation:
| Code | Explanation |
|---|---|
| int x =50; | Declare variable name x with data type int and store 50 inside it.Declare variable name y with data type int and store 5 inside it. |
| if(!(x>40)) | Checking logically not condition, if x is greater than 40 is true because x contain 50 now as we using logical not ! operator so it’s return false |
| System.out.println("False"); | As ! condition return false because x>40 return true, so False will be printed on the screen. |
| System.out.println("True"); | If x>40 return false than ! operator returns true and True will be printed on the screen. |
(3)Assignment Operators in Java Operators
Assignment operators are used to assign values to variables.
| Operator | Example | Equal To |
|---|---|---|
| = | x=10 | x=10 |
| += | x+=4 | x=x+4 |
| *= | x *=4 | x=x*4 |
| -= | x-=6 | x=x-6 |
| /= | x /=2 | x = x/2 |
| %= | x%2 | x=x%2 |
= Operator
Explanation:
| Code | Description |
|---|---|
| int x =50; | = Operate assign the value to x which is 50 |
| System.out.println(x); | System.out.println() is the function which take argument name x which contain value 50 and print on the console. |
+= Operator
Explanation:
| Code | Description |
|---|---|
| int x =50; | = Operate assign the value to x which is 50 |
| x+=4 | x+=4 is equal to x=x+4 so as x=50 and x=50+4, so now x contains 54. |
| System.out.println(x); | System.out.println() is the function which take argument name x which contain value 54 and print on the console. |
*= Operator
Explanation:
| Code | Description |
|---|---|
| int x =50; | = Operate assign the value to x which is 50 |
| x*=4 | x*=4 is equal to x=x*4 so as x=50 and x=50*4, so now x contains 200. |
| System.out.println(x); | System.out.println() is the function which take argument name x which contain value 200 and print on the console. |
-= Operator
Explanation:
| Code | Description |
|---|---|
| int x =50; | = Operate assign the value to x which is 50 |
| x-=4 | x-=4 is equal to x=x-4 so as x=50 and x=50-4, so now x contains 46. |
| System.out.println(x); | System.out.println() is the function which take argument name x which contain value 46 and print on the console. |
/= Operator
Explanation:
| Code | Description |
|---|---|
| int x =50; | = Operate assign the value to x which is 50 |
| x/=2 | x/=2 is equal to x=x/2 so as x=50 and x=50/2, so now x contains 25. |
| System.out.println(x); | System.out.println() is the function which take argument name x which contain value 25 and print on the console. |
%= Operator
Explanation:
| Code | Description |
|---|---|
| int x =23; | = Operate assign the value to x which is 23 |
| x%=2 | x%=2 is equal to x=x%2 so as x=23 and x=23%2, so x contains 1 as the remainder is 1. |
| System.out.println(x); | System.out.println() is the function which take argument name x which contain value 1 and print on the console. |

Comparison operators are used to compare two values stored inside variables.
Following comparison operators are used in java language.
| Operator | Name | Description | Example |
|---|---|---|---|
| == | Equal to | Checking value stored inside x variable is equal to value stored inside variable y. | x == y |
| != | Not equal to | Checking value stored inside x is not equal to value stored inside variable y. | x != y |
| > | Greater than | Checking value stored inside x is greater than value stored inside variable y. | x > y |
| < | Less than | Checking value stored inside x is less then value stored inside variable y. | x < y |
| >= | Greater Than or equal to | Checking value stored inside x is equal to or greater than to value stored inside variable y. | x >= y |
