How to convert a boolean to string in Java :
In this quick tutorial, we will learn how to convert a boolean value to string in Java. Not only one, we have two different ways to do the conversion. Let’s take a look :
Using Boolean.toString() :
Boolean class has one static method toString to convert a boolean value to string. The method definition is as below :
public static String valueOf(boolean b)
-
We need to pass one boolean value as parameter to this function.
-
It will return the string representation of the boolean value.
Now, let’s try it with an example :
class Example {
public static void main(String args[]) {
boolean firstBoolean = true;
boolean secondBoolean = false;
System.out.println("The value of firstBoolean is "+Boolean.toString(firstBoolean));
System.out.println("The value of secondBoolean is "+Boolean.toString(secondBoolean));
}
}
It will print the below output :
The value of firstBoolean is true
The value of secondBoolean is false
As you can see that we have two Boolean variables with true and false values. With the Boolean.toString() methods, they are converted to string “true” and “false” respectively.
Using String.valueOf() :
Similar to the above example, we also have one static method in the String class : valueOf(). The definition of this method is as below :
public static String valueOf(boolean b)
-
Similar to the above example, valueOf method takes one boolean as parameter and returns one string.
-
It is also a static method similar to the above one.
Example of valueOf() :
class Example {
public static void main(String args[]) {
boolean firstBoolean = true;
boolean secondBoolean = false;
System.out.println("The value of firstBoolean is "+String.valueOf(firstBoolean));
System.out.println("The value of secondBoolean is "+String.valueOf(secondBoolean));
}
}
Output :
The value of firstBoolean is true
The value of secondBoolean is false
