Byte compareTo() method in Java with examples

The compareTo() method of Byte class is a built in method in Java which is used to compare the given Byte type object with the instance of Byte invoking the compareTo() method.

Syntax

ByteObject.compareTo(Byte a)

Parameters: It takes a Byte type object a as input which is to be compared with the instance of the Byte object calling the compareTo method.

Return Value: It returns an int value. It returns:

• 0 if ‘a is equal to ‘b,
• a positive value ‘a’ is greater than ‘b’,
• a negative value ‘b’ is greater than ‘a’

Below is the implementation of compareTo() method in Java:

Example 1:

// Java code to demonstrate
// Byte compareTo() method

class GFG {
    public static void main(String[] args)
    {

        // creating a Byte object
        Byte a = new Byte("20");

        // creating a Byte object
        Byte b = new Byte("20");

        // compareTo method in Byte class
        int output = a.compareTo(b);

        // printing the output
        System.out.println("Comparing " + a
                           + " and " + b + " : "
                           + output);
    }
}

Output:

Comparing 20 and 20 : 0

Example 2:

// Java code to demonstrate
// Byte compareTo() method

class GFG {
    public static void main(String[] args)
    {

        // creating a Byte object
        Byte a = new Byte("20");

        // creating a Byte object
        Byte b = new Byte("10");

        // compareTo method in Byte class
        int output = a.compareTo(b);

        // printing the output
        System.out.println("Comparing " + a
                           + " and " + b + " : "
                           + output);
    }
}

Output:

Comparing 20 and 10 : 10

Example 3:

// Java code to demonstrate
// Byte compareTo() method

class GFG {
    public static void main(String[] args)
    {

        // creating a Byte object
        Byte a = new Byte("10");

        // creating a Byte object
        Byte b = new Byte("20");

        // compareTo method in Byte class
        int output = a.compareTo(b);

        // printing the output
        System.out.println("Comparing " + a
                           + " and " + b + " : "
                           + output);
    }
}

Output:

Comparing 10 and 20 : -10
