“Boolean Operators” serve a dedicated purpose in Java. It is such that these operators play a fundamental role in building the logic for the programmer. These operators also come into effect while solving the complex algorithms involving multiple expressions. In addition to that, these operators also assist in solving the mathematical queries effectively.
What are the Boolean Operators in Java?
Java provides a primitive data type called “Boolean” that retrieves the values “true” or “false”.
Following are the vital Boolean operators in Java:
| Boolean Operators | Working |
|---|---|
| == (equal to) | This operator verifies if the values of both the operands are equal. If so, the condition becomes true. |
| != (not equal to) | It analyzes if the values of two operands are equivalent and gives true if the values are not equivalent. |
| && (logical AND) | This operator gives true if both the conditions are true. |
| || (logical OR) | This operator gives true if either of the conditions are true. |
| ! (logical NOT) | This operator reverses the logical state. It is such that if a condition is true, it negates the outcome as false. |
The next section includes the implementation of the Boolean operators.
Example 1: Applying the Boolean Operators in Java
This example applies the Boolean operators upon the defined integer values:
public class Booleanoperators {
public static void main (String args[]) {
int a = 2;
int b = 5;
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);
}}
In this code, initialize the given integers to be evaluated. Now, apply the stated Boolean operators to check if the first value is equal, greater, less, greater than or equal, less than or equal, or not equal to the second value, respectively.
Output
The corresponding Boolean outcome is retrieved in each case.
Example 2: Applying the Logical Boolean Operators in Java
This code demonstration implements the logical Boolean operators upon the initialized integers:
public class Booleanoperators {
public static void main (String args[]) {
int a = 2;
int b = 5;
System.out.println(((a > b || a == 2)));
System.out.println((!(a < b && a > 1)));
}}
In this snippet of code, perform the below-provided steps:
- Initialize the stated integers.
- Now, apply the logical OR “||” operator to verify if both the left and right conditions are true.
- In this scenario, both the conditions are satisfied, so the result will be evaluated as “true”.
- After that, apply the combined logical NOT “!” and logical AND “&&” operators. It is such that the latter operator returns “true” if both the conditions are true which is the case here and the former operator negates the outcome, thereby returning “false”.
Output
Conclusion
Java provides a primitive data type called “Boolean” that returns the values “true” or “false”. These include == , !=, >, >=, <, <=, !, &&, ||. These operators evaluate the applied conditions on the defined or user-input values and return the corresponding Boolean outcome.
