Operators are essential components of programming languages and are used to perform operations on data. In Java, operators are special symbols that allow programmers to manipulate variables and values in different ways. The Java programming language supports different types of operators, including arithmetic, logical, and relational operators.
Arithmetic Operators
Arithmetic operators are used to perform basic mathematical operations such as addition, subtraction, multiplication, and division. These operators are often used in programs that perform calculations or manipulate numerical data. The following table shows the arithmetic operators in Java:
| Operator | Description |
|---|---|
| + | Addition |
| – | Subtraction |
| * | Multiplication |
| / | Division |
| % | Modulus (remainder) |
Logical Operators
Logical operators are used to perform logical operations such as AND, OR, and NOT. These operators are used to evaluate conditions and perform actions based on the results of those evaluations. The following table shows the logical operators in Java:
| Operator | Description |
|---|---|
| && | Logical AND |
| ! | Logical NOT |
Relational Operators
Relational operators are used to compare two values and return a boolean value (true or false). These operators are used to evaluate conditions and perform actions based on the results of those evaluations. The following table shows the relational operators in Java:
| Operator | Description |
|---|---|
| == | Equal to |
| != | Not equal to |
| > | Greater than |
| < | Less than |
| >= | Greater than or equal to |
| <= | Less than or equal to |
Overall, understanding these operators is essential to writing effective programs in Java. By using these operators, programmers can manipulate data, evaluate conditions, and perform a wide range of tasks in their programs.
