While learning Java, you will come across the concept of operators. What is a Java operator? Java operators are symbols useful for performing operations on variables. They also help manipulate the values of the operands.
The different Java operators are useful for performing various functions. Dive into this article to learn more about Java operators, their types, and their importance.
Once you know what is a Java operator, you must consider its importance. You should know that operators in Java are extremely vital. Without Java operators, you won’t be able to make logical, arithmetic calculations in different programs.
According to the type of Java operators, they manipulate a logical or arithmetic value or operand in a certain way to deliver a specific outcome. Operators in Java play a crucial role in the programming world by dealing with simple arithmetic functions and executing complex algorithms. Java operators are also responsible for key functions like security encryption.

Different Types of Operators in Java
Now that you know what is a Java operator, you should learn about the different types of operators in Java.
Arithmetic Operators
Ternary Operators
Bitwise Operator
Relational Operators
Logical Operators
Unary Operators
Assignment Operator
Shift Operator in Java
1. Arithmetic Operators in Java
Arithmetic operators in Java are useful for executing addition, multiplication, division, subtraction, and modulus. As you can see, these operators in Java are valuable for mathematical operations.
Examples of Arithmetic Operators (Kindly put all the code related content in a highlighted section)
public class Herovired {
public static void main ( String[] args ) {
int a = 10;
int b = 20;
System.out.println ( a + b );
System.out.println ( a – b );
System.out.println ( a * b );
System.out.println ( a / b );
System.out.println ( a % b );
}
}
2. Ternary Operators in Java
The ternary operator in Java is conditional. These Java operators can help minimize the line of code while making comparisons. The ternary operator in Java is a replacement for nested if-else or if-else statements. Sometimes, the ternary operator in Java is also called the conditional operator, inline if, or ternary if.
Examples of Ternary Operator Java
public class Herovired {
public static void main ( String args[] ) {
int a = 4;
int b = 9;
int min = ( a<b></b>
The bitwise operator in Java operates on a bit array, bit string, or binary number. The fast and simple operator in Java is directly supported by the processor. You can also refer to the bitwise operation as bit-level programming.
Examples of Bitwise Operators in Java
public class Herovired {
public static void main( String[] args ) {
int a = 58;
int b = 13;
System.out.println ( a&b );
System.out.println ( a|b );
System.out.println ( a^b );
System.out.println ( ~a );
}
}
4. Relational Operators in Java
The relational operators in Java can compare two numbers to deliver a boolean value. This operator can be useful for defining a test or relation between two operands.
Examples of Relational operators in Java
public class Herovired {
public static void main ( String[] args ) {
int a = 10;
int b = 20;
System.out.println ( a < b ); System.out.println( a > b );
System.out.println ( a <= b ); System.out.println (a >= b );
System.out.println ( a == b );
System.out.println ( a != b );
}
}
Logical operators in Java help combine two or more conditions. It is useful for performing the original condition under consideration.
Examples of Logical Operators in Java
public class Herovired {
public static void main ( String args[] ) {
int a = 5;
System.out.println ( a<5 && a<20 );
System.out.println ( a<5 || a<20 );
System.out.println ( ! ( a<5 && a<20 ));
}
}
6. Unary Operators in Java
The unary operators in Java demand a single operand. These Java operators can increase or decrease the value. As a result, an expression becomes negative, or the boolean value gets inverted.
Examples of Unary Operators in Java
public class Herovired {
public static void main ( String[] args ) {
int a = 10;
boolean b = True;
System.out.println ( a++ );
System.out.println ( ++a );
System.out.println ( a-- );
System.out.println ( --a );
System.out.println ( !b );
}
}
The assignment operators in Java are beneficial for allocating new values to a variable. In assignment operators in Java, the left side is called a variable. The right side of these Java operators is called value.
Examples of Assignment Operators in Java
public class Herovired {
public static void main ( String[] args ) {
int a = 10;
int b = 20;
int c;
System.out.println ( c = a );
System.out.println ( b += a );
System.out.println ( b -= a);
System.out.println ( b *= a );
System.out.println ( b /= a );
System.out.println ( b ^= a );
System.out.println ( b %= a );
}
}
8. Shift Operator in Java
The shift operator in Java can transfer bits of a number to the left or right. The shift can be performed by dividing or multiplying the numbers.
Examples of Shift Operators in Java
public class Herovired {
public static void main ( String args[] ) {
int a = 58;
System.out.println ( a<<2 ); System.out.println ( a>>2 );
}
}
Operators in Java play a crucial role in performing several data operations. Every type of Java operator has its own specific set of functions. Some Java operators are used more frequently than others. But every operator in Java is used when the need arises. If you want to become proficient in Java, you must possess in-depth knowledge about what is a Java operator.
FAQs
What is the ternary operator in Java, and how does it differ from other conditional statements?
The ternary operator in Java helps evaluate Boolean expressions. Unlike other operators in Java, the ternary operator can accept three operands.
How can I use assignment operators in Java to simplify my code and improve readability?
The assignment operators in Java can help assign values to variables. They can help simplify and improve the readability of your code by shortening it.
What are the advantages and limitations of using shift operators in Java?
The shift operator can help move bits of the first operand left or right to manipulate data. But the limitation of the shift operators in Java is that they are only applicable to linear sequences.
How do I use the comparison operators in Java to compare two values and return a boolean result?
The comparison operators in Java can help compare two values to perform a code block and establish a variable’s value according to the outcome. But to return a boolean result, the value should either be true or false.
What are the best practices for using Java operators in my code to ensure readability and maintainability?
Maintaining proper naming conventions while using Java operators can improve code readability. It’s also crucial to avoid negations, abbreviations, and general terms to maintain code well.
