Convert Boolean to String

This program helps you in converting the Boolean type data into a string. The toString() method reads the Boolean type object and it converts into a string format. This method returns a string object and represents the boolean’s value. The Boolean object represents either “true” or “false".

code

Code:

import java.util.*;

public class BooleanToString{
  public static void main(String[] args){
    boolean b = true;
    String s = new Boolean(b).toString();
    System.out.println("String is:"+ s);
  }
}

Output

Code:

C:\corejava>java BooleanToString
String is:true
C:\corejava>

Convert String to Boolean

Try this for reverse conversion from string data type to boolean.
There are 2 ways to do so.
1. you can create an instance of the wrapper class Boolean with a string value as argument to the constructor and call the method booleanValue()
2. call the static method parseBoolean() of the wrapper class to convert the string value to a boolean.
Note : The string value sent in has to be either 'true' or 'TRUE' to result in a boolean with the value of true, but it doesn't have to be 'false' to result in a false boolean value.
It actually makes sense that any other string value than 'true' or 'TRUE' will result in a return value that is set to false.

Code:

/**
 * Main.java
 *
 * @author www.javadb.com
 */
public class Main {
    
    /**
     * String to boolean conversion
     */
    public void convertStringToBoolean() {
        
        String strBoolean = "true";
        
        //Do the String to boolean conversion
        boolean theValue = Boolean.parseBoolean(strBoolean);
        
        System.out.println(theValue);
    }
    
    /**
     * Starts the program
     *
     * @param args the command line arguments
     */
    public static void main(String[] args) {
        new Main().convertStringToBoolean();
    }
}
