Java Program to convert boolean to integer

Last Updated : 25 Apr, 2023

Given a boolean value, the task is to convert this boolean value into an integer value in Java. Examples:

Input: boolean = true
Output: 1

Input: boolean = false
Output: 0

Approach:

Get the boolean value to be converted.
Check if boolean value is true or false
If the boolean value is true, set the integer value as 1.
Else if the boolean value is false, set the integer value as 0.

Below is the implementation of the above approach: Example 1: When boolean value is true

Java

// Java Program to convert boolean to integer

public class GFG {

    public static void main(String[] args)
    {

        // The boolean value
        boolean boolValue = true;

        // The expected integer value
        int intValue;

        // Check if it's true or false
        if (boolValue) {
            intValue = 1;
        }
        else {
            intValue = 0;
        }

        // Print the expected integer value
        System.out.println(
            boolValue
            + &quot; after converting into integer = &quot;
            + intValue);
    }
}

Output:

true after converting into integer = 1

The time complexity is O(1), which means it will take a constant amount of time to execute, regardless of the input size.

The auxiliary space used by the program is also constant.

Example 2: When boolean value is false

Java

// Java Program to convert boolean to integer

public class GFG {

    public static void main(String[] args)
    {

        // The boolean value
        boolean boolValue = false;

        // The expected integer value
        int intValue;

        // Check if it's true or false
        if (boolValue) {
            intValue = 1;
        }
        else {
            intValue = 0;
        }

        // Print the expected integer value
        System.out.println(
            boolValue
            + &quot; after converting into integer = &quot;
            + intValue);
    }
}

Output:

false after converting into integer = 0
