Can I convert boolean into another data type in Java

Question

I have the following code:

public class MyFirstJavaProgram {
        public static void main(String []args) { 
          boolean b = true; 
          int x = b; 
          System.out.println(x);
    }
} 

As the title say, can I convert boolean type into another data type (in the above example, char), using Java?

Answer 1

No you cannot.

If you are looking for a one-line solution to set your int, you can use a ternary operation, as such:

int x = b ? 1 : 0;

Answer 2

You can't do it directly, but you can do it on this way:

int myIntBool = (someBoolean) ? 1 : 0;

Also, you can use BooleanUtils from Apache.

BooleanUtils.toInteger(true)  = 1
BooleanUtils.toInteger(false) = 0

Answer 3

You can do int x = b ? 1 : 0;.

Answer 4

NO You use ternary operation

          int X = value ? 1: 0;

Answer 5

ternary operation will yield the result

int y = booleanvalue ? 1: 0;

Answer 6

Boolean To int

int convertedInt=0;

if(booleanToConvert)
  convertedInt=1;

Boolean to char

char convertedChar='';

if(booleanToConvert)
  convertedChae='Y';
else
  convertedChae='N';

Answer 7

you cannot directly convert but manually like so:

int x = b ? 1 : 0; //sets x to 1 if b is true, 0 otherwise

The question now is why would you want to do this?

Answer 8

char c = Boolean.parseBoolean("true") ? '1' : '0'; would set c to 1. not quite sure if that is what you want.

Answer 9

boolean to int:

return booleanValue ? 1 : 0;

boolean to char:

return booleanValue ? 'Y' : 'N';

boolean to String:

return booleanValue ? "YES" : "NO";

And so on...
