Following is the declaration for java.lang.Boolean.toString() method
public static String toString(boolean b)
Parameters
b − the boolean to be converted

This method returns the string representation of the specified boolean.
Exception
NA
Example 1
The following example shows the usage of Boolean toString() method for a boolean value as true.
package com.tutorialspoint; public class BooleanDemo { public static void main(String[] args) { // create 1 bool variable b1 boolean b1; // assign value to b1 b1 = true; // create 1 String s1 String s1; // assign string value of object b1 to s1 s1 = Boolean.toString(b1); String str1 = "String value of boolean object " + b1 + " is " + s1; // print s1 value System.out.println( str1 ); } }
Output
Let us compile and run the above program, this will produce the following result −
String value of boolean value true is true
Example 2
The following example shows the usage of Boolean toString() method for a boolean value as false.
package com.tutorialspoint; public class BooleanDemo { public static void main(String[] args) { // create 1 bool variable b1 boolean b1; // assign value to b1 b1 = false; // create 1 String s1 String s1; // assign string value of object b1 to s1 s1 = Boolean.toString(b1); String str1 = "String value of boolean object " + b1 + " is " + s1; // print s1 value System.out.println( str1 ); } }
Output
Let us compile and run the above program, this will produce the following result −
String value of boolean value false is false
