Convert String Object to Boolean Object in Java

Description

How to convert String object to Boolean object.

Example

In this example we are gonna see two methods of String to Boolean object conversion.

class StringObjToBooleanObj {
   public static void main(String[] args) {
      // String Objects
      String str = "false";
	    
      // Case does not matter for conversion
      String str2 = "TrUe";
	   
      /* Method 1: Using Constructor - 
       * Passing string value to the constructor
       * of Boolean class.
       */
      Boolean bobj = new Boolean(str);
      Boolean bobj2 = new Boolean(str2);
      System.out.println(bobj);
      System.out.println(bobj2);
	   
      /* Method 2: Using valueOf() method of
       * Boolean class
       */
      Boolean bobj3 = Boolean.valueOf(str);
      Boolean bobj4 = Boolean.valueOf(str2);
      System.out.println(bobj3);
      System.out.println(bobj4);
  }  
}

Output:

false
true
false
true

public static Boolean valueOf(String s): Returns a Boolean with a value represented by the specified string. The Boolean returned represents a true value if the string argument is not null and is equal, ignoring case, to the string “true”.
