When you write code you’ll almost always need to perform some kind of arithmetic operation. This can be something as simple as adding two numbers or something a little more complex like solving for the fourth root of a number.

To do this, you’ll need to use an arithmetic operator in Java. Arithmetic operators are used in arithmetic expressions to perform addition, subtraction, multiplication, and division on one or more values.

An arithmetic expression is a combination of numbers, variables, and operators that evaluates to a single value. First we will cover the different types of Arithmetic Operators in Java and then the specific examples on how to use them properly.

**Arithmetic Operators in java**

There are several arithmetic operators that are used in Java for different operations.

– addition : To add two numbers.

– subtraction : To subtract one number from the other.

– multiplication : To multiply two numbers together.

– division : To divide one number by another.

– modulo division : To find the remainder after division.

**Addition in Java**

To add two numbers together you will use the + operator. You can add any number of numbers together in a single expression.

The order of operations will add the first number, then the second, then the third, and so on. In the following example we will add two numbers together and then add a third number to that result.

When you run this code you will get the result of 25. The + operator can also be used to concatenate strings together. When adding strings you must use the + operator to do so.

**Subtraction in Java**

To subtract one number from another you will use the – operator. Just like the addition operator you can subtract any number of numbers in a single expression.

The order of operations will subtract the first number, then the second, then the third, and so on. In the following example we will subtract two numbers together and then subtract a third number from that result.

When you run this code you will get the result of 19. The – operator can also be used to remove a substring from a string. When removing a substring from a string you must use the – operator to do so.

**Multiplication in Java**

To multiply two numbers together you will use the * operator. Just like the addition and subtraction operators you can multiply any number of numbers in a single expression.

The order of operations will multiply the first number, then the second, then the third, and so on. In the following example we will multiply two numbers together and then multiply a third number to that result.

When you run this code you will get the result of 36. The * operator can also be used to multiply strings together. When multiplying strings you must use the * operator to do so.

**Division in Java**

To divide one number by another you will use the / operator. Just like the addition, subtraction, and multiplication operators you can divide any number of numbers in a single expression.

The order of operations will divide the first number, then the second, then the third, and so on. In the following example we will divide two numbers together and then divide a third number from that result.

When you run this code you will get the result of 6.5. The / operator can also be used to find the remainder after division.

**Constant Value Operator**

The constant value operator is used to assign a specific constant value to a variable. This can be used as a shortcut for writing a longer expression.

The constant value operator is written with two backslashes \ followed by a number. In the following example we will assign the value of pi to the variable pi. When you run this code you will get the following output.

**Conclusion**

Arithmetic operators are used in Java to perform addition, subtraction, multiplication, and division on one or more values.

An arithmetic expression is a combination of numbers, variables, and operators that evaluates to a single value.

First we will cover the different types of Arithmetic Operators in Java and then the specific examples on how to use them properly.
