Discussion :

The string valueOf(boolean b) method is to get a String equivalent of boolean method parameter. This method be statically accessed which means we should call the method like String.valueOf(boolean value).

Java Code Example :

This example source code demonstrates the use of valueOf(Boolean b) of String class. We have used the contains() method of String class to evaluate if String contains a string “Male”. This is simply to print the value of a boolean datatype. Since the sample string contains a String “Male”, the console output is true.

package com.javatutorialhq.java.tutorial.string;

/*
 * Java example source code to get the value of boolean data type
 */

public class StringValueOfBoolean {

	public static void main(String[] args) {

		// declare a sample string value
		String strValue = "Will Smith-Male-USA";
		// check if String value contains a specific string
		boolean bool = strValue.contains("Male");
		// print the string equivalent of our boolean check
		System.out.println(String.valueOf(bool));
	}

}
