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
