Boolean toString() Method in Java

In Java, the toString() method of the Boolean class is used to convert a boolean value into its string representation. The Boolean class belongs to the java.lang package. The Boolean class provides both a static toString(boolean) method and an instance toString() method for obtaining the string representation of a boolean value.

• The returned string is either "true" or "false".
• The method is useful when a boolean value needs to be represented as text.

Syntax

public static String toString(boolean b)

• Parameter: b is the boolean value to be converted.
• Return Value: Returns "true" if the value is true, otherwise returns "false".

class Geeks
 { 
	public static void main(String[] args) 
	{ 
		// boolean type value 
		boolean value = true; 

		// static toString() method of Boolean class 
		String output = Boolean.toString(value); 

		// printing the value 
		System.out.println(output); 
	} 
} 

true

Explanation: boolean value = true; creates a boolean variable with the value true. The Boolean.toString(value) method converts this boolean value into its string representation "true", which is stored in the output variable. Finally, System.out.println(output) prints the string true to the console

Example: Using Boolean.toString() method to convert false boolean value to its string representation.

class Geeks
{ 
	public static void main(String[] args) 
	{ 
		// boolean type value 
		boolean value = false; 

		// static toString() method of Boolean class 
		String output = Boolean.toString(value); 

		// printing the value 
		System.out.println(output); 
	} 
} 

false

Explanation: boolean value = false; creates a boolean variable with the value false. The Boolean.toString(value) method converts the boolean value into the string "false" and stores it in the output variable. The System.out.println(output) statement then prints false to the console.
