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
