Compare boolean values in java – compareTo() Method

Description

Program to compare boolean values.

Example

In this example we are going to see how to compare two boolean values by using compareTo() method of Boolean class.

class CompareBooleanValues {
 
  public static void main(String[] args) {
    // Creating Objects of Boolean class
    Boolean bObj = new Boolean("true");
    // Case does not matter
    Boolean bObj2 = new Boolean("FaLsE");
    Boolean bObj3 = new Boolean("true");
 
    // Comparing values using compareTo() method
    /* public int compareTo(Boolean b): It returns zero if 
     * the object represents the same boolean value as
     * the argument; a positive value if this object 
     * represents true and the argument represents false; 
     * and a negative value if this object represents 
     * false and the argument represents true
     */
    System.out.println(bObj.compareTo(bObj2));//+ve
    System.out.println(bObj.compareTo(bObj3));//Zero
    System.out.println(bObj2.compareTo(bObj3));//-ve
  }
}

Output:

1
0
-1
