I'd be happy to respond in English!

Arithmetic Operators in Java:

Arithmetic operators are used to perform mathematical operations on variables, constants and expressions involving numbers. In Java, there are five basic arithmetic operators: addition (+), subtraction (-), multiplication (*), division (/), and modulus (%). Here's a breakdown of each operator with examples:

Addition (+=):

The addition operator is used to add the value of one operand to another.

Example:

int a = 10;
int b = 5;
a += b; // equivalent to a = a + b;
System.out.println(a); // outputs: 15

Subtraction (-=):

The subtraction operator is used to subtract the value of one operand from another.

Example:

int a = 10;
int b = 5;
a -= b; // equivalent to a = a - b;
System.out.println(a); // outputs: 5

Multiplication (*=):

The multiplication operator is used to multiply the value of one operand by another.

Example:

int a = 10;
int b = 2;
a *= b; // equivalent to a = a * b;
System.out.println(a); // outputs: 20

Division (/=):

The division operator is used to divide the value of one operand by another.

Example:

int a = 12;
int b = 3;
a /= b; // equivalent to a = a / b;
System.out.println(a); // outputs: 4

Modulus (%=):

The modulus operator is used to find the remainder of one operand divided by another.

Example:

int a = 12;
int b = 3;
a %= b; // equivalent to a = a % b;
System.out.println(a); // outputs: 0

These operators can be combined with variables, constants and expressions involving numbers. For example:

int a = 10;
int b = 5;
int c = 2;
a = a + b * c; // equivalent to a = (a + (b * c))
System.out.println(a); // outputs: 20

Arithmetic operators are essential in programming as they allow you to manipulate numbers and perform complex calculations.

Please note that this is not an exhaustive list of arithmetic operators or their examples. However, it should provide a good starting point for understanding the basic arithmetic operations in Java.

Arithmetic operators in Java are used to perform mathematical operations on variables and values. Here's a list of the basic arithmetic operators, along with their meanings and examples:

Addition (+): Adds two operands together.

Example:

int x = 5;
int y = 2;
int sum = x + y; // sum is 7

Subtraction (-): Subtracts the second operand from the first.

Example:

int x = 5;
int y = 2;
int difference = x - y; // difference is 3

Multiplication (*): Multiplies two operands together.

Example:

int x = 5;
int y = 2;
int product = x * y; // product is 10

Division (/ or % for integer division): Divides the first operand by the second, and returns the result as a floating-point number (using /) or an integer (using %).

Example:

int x = 10;
int y = 2;
float quotient = x / y; // quotient is 5.0
int remainder = x % y; // remainder is 0

Modulus (%): Returns the remainder of the division operation.

Example:

int x = 17;
int y = 5;
int remainder = x % y; // remainder is 2

Increment (++): Increments a variable by 1.

Example:

int x = 5;
x++; // x is now 6

Decrement (--): Decrements a variable by 1.

Example:

int x = 5;
x--; // x is now 4

Here are some more complex examples:

Assignment with addition: a += b; is equivalent to a = a + b; Assignment with subtraction: a -= b; is equivalent to a = a - b; Assignment with multiplication: a *= b; is equivalent to a = a * b; Assignment with division: a /= b; is equivalent to a = a / b;

These arithmetic operators are used extensively in Java programming, especially when working with variables and mathematical calculations.
